End Key Contacts Chapter
Thank you for your willingness to serve members of the Montana Healthcare Programs and other medical assistance programs administered by the Department of Public Health and Human Services.
This manual provides information specifically for hospital inpatient services. Other essential information for providers is contained in the separate General Information for Providers manual. Providers are responsible for reviewing both manuals.
A table of contents and an index allow you to quickly find answers to most questions. The margins contain important notes with extra space for writing notes. There is a list of contacts at the beginning of each manual. There is also space on the inside of the front cover to record your NPI for quick reference when calling Provider Relations.
Manuals must be kept current. Changes to manuals are provided through provider notices and replacement pages. Manual replacement pages can be downloaded from the provider type pages on the Provider Information website and are identified by a note at the top of the page indicating Replacement Page and the date. They are designed to be printed on the front and back of each page, so they are always in sets of two beginning with an odd page followed by an even page, even though one of the pages may not have any changes. When replacing a page in a paper manual, file the old pages and provider notices in the back of the manual for use with claims that originated under the old policy.
Providers must be familiar with all current rules and regulations governing the Montana Healthcare Programs. Provider manuals are to assist providers in billing Montana Healthcare Programs; they do not contain all Montana Healthcare Programs rules and regulations. Rule citations in the text are a reference tool; they are not a summary of the entire rule. In the event that a manual conflicts with a rule, the rule prevails. Links to rules are available on the Provider Information website. Paper copies of rules are available through the Secretary of State’s office. See the Contact Us link in the left menu on the Provider Information website.
Providers are responsible for knowing and following current Montana Healthcare Programs rules and regulations.
In addition to the general Montana Healthcare Programs rules outlined in the General Information for Providers manual, the following rules and regulations are also applicable to the hospital inpatient program:
The Department is committed to paying Montana Healthcare Programs providers’ claims as quickly as possible. Montana Healthcare Programs claims are electronically processed and usually are not reviewed by medical experts prior to payment to determine if the services provided were appropriately billed. Although the computerized system can detect and deny some erroneous claims, there are many erroneous claims it cannot detect. For this reason, payment of a claim does not mean the service was correctly billed or the payment made to the provider was correct. Periodic retrospective reviews are performed that may lead to the discovery of incorrect billing or incorrect payment. If a claim is paid and the Department later discovers the service was incorrectly billed or paid or the claim was erroneous in some other way, the Department is required by federal regulation to recover any overpayment, regardless of whether the incorrect payment was the result of Department or provider error or other cause.
The provider manuals are designed to answer most questions; however, questions may arise that require a call to a specific group (such as a program officer, Provider Relations, or a prior authorization unit). A list of key contacts and websites is available online. On the Provider Information website, choose the Contact Us link in the left menu. Providers should also read the monthly Claim Jumper newsletter for Montana Healthcare Programs updates and changes. Montana Healthcare Programs provider manuals, provider notices, replacement pages, fee schedules, forms, and more are available on the Provider Information website.
End of Introduction Chapter
Montana Healthcare Programs covers inpatient hospital services when they are medically necessary. This chapter provides covered services information that applies specifically to inpatient hospital services. Like all healthcare services received by Montana Healthcare Programs members, these services must also meet the general requirements listed in the Provider Requirements chapter of the General Information for Providers manual.
Hospital Inpatient Services (ARM 37.86.2801–2950)
Inpatient hospital services are provided to Montana Healthcare Programs members who are formally admitted as an inpatient and whose expected hospital stay is greater than 24 hours. Inpatient services must be ordered by a licensed physician or dentist and provided in an institution maintained primarily for treatment and care of patients with disorders other than tuberculosis or mental diseases. The institution must be currently licensed by the designated state licensing authority in the state where the institution is located, must meet the requirements for participation in Medicare as a hospital, and must have in effect a utilization review plan that meets the requirements of 42 CFR 482.30.
Services for Children (ARM 37.86.2201–2235)
The Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) Services program is a comprehensive approach to healthcare for Montana Healthcare Programs members ages 20 and under. It is designed to prevent, identify, and then treat health problems before they become disabling. Under EPSDT, Montana Healthcare Programs eligible children may receive any medically necessary covered service, including all inpatient hospital services described in this manual. All applicable Passport to Health and prior authorization requirements apply.
Importance of Fee Schedules
The easiest way to verify coverage for a specific service is to check the Department’s fee schedule for your provider type. In addition to being listed on the fee schedule, all services provided must also meet the coverage criteria listed in the Provider Requirements chapter of the General Information for Providers manual and in this chapter. Use the fee schedule in conjunction with the more detailed coding descriptions listed in the current ICD coding book. Take care to use the fee schedule and coding books that pertain to the date of service. Fee schedules are available on the Provider Information website.
At the time a claim is submitted, the hospital must have on file a signed and dated acknowledgment from the attending physician that the physician has received the following notice:
Notice to physicians: Montana Healthcare Programs payment to hospitals is based on all of each patient’s diagnoses and the procedures performed on the patient, as attested to by the patient's attending physician by virtue of his or her signature in the medical record. Anyone who misrepresents, falsifies or conceals essential information required for payment of federal funds, may be subject to fine, imprisonment or civil penalty under applicable federal laws.
The acknowledgement must be completed by the physician at the time that the physician is granted admitting privileges at the hospital, or before or at the time the physician admits his/her first member to the hospital. Existing acknowledgments signed by physicians already on staff remain in effect as long as the physician has admitting privileges at the hospital. The provider may, at its discretion, add to the language of this statement the word Medicare so that two separate forms will not be required by the provider to comply with state and federal requirements.
The Department or its contractor may at any time review paid claims, provider documentation for medical necessity, appropriate billing, etc. Providers must maintain documentation of medical necessity for services such as initial hospitalization, transfers, and readmissions. For more information on provider requirements for maintaining documentation, see the Record Keeping section in the Provider Requirements chapter of the General Information for Providers manual. Also see the Claims Review section in the Introduction chapter of this manual.
Providers must contact the Department to obtain hospital residence status prior to billing Montana Healthcare Programs. To qualify for residency status, a member must meet the following requirements:
It is the provider’s responsibility to determine whether services could be provided in a skilled nursing care facility or by the Home and Community-Based Waiver Program. The provider must maintain written records of inquiries and responses about the present and future availability of openings in nursing facilities and the Home and Community-Based Waiver Program. A redetermination of nursing facility or waiver availability must be made at least every 6 months.
Hospitalized Montana Healthcare Programs members and Montana Healthcare Programs applicants being considered for nursing facility placement from the hospital shall be referred in a timely manner to the preadmission screening team. The preadmission screening form (Form DPHHS-SLTC-61) must be completed before placement and payment is made on their behalf.
Elective Deliveries
Effective July 1, 2014, all facilities must have a hard-stop policy in place regarding non-medically necessary inductions prior to 39 weeks and nonmedically necessary Cesarean sections at any gestational age. The policy must contain the following:
Effective October 1, 2014, Montana Healthcare Programs will reduce reimbursement rates for non-medically necessary inductions prior to 39 weeks, and non-medically necessary Cesarean sections at any gestational ages. All hospital claims with an admit date on or after October 1, 2014, will require coding changes to delivery claims.
Hospital inpatient claims and birthing center claims will require the use of condition codes for all induction and Cesarean section deliveries. These claims will be reviewed for medical necessity based on an approved list of diagnosis codes. The condition codes are:
Clinical Trials (ARM 37.86.2902)
Clinical trial drugs, devices, and procedures are not reimbursable. Clinical trials are limited to Montana Healthcare Programs coverage of routine costs plus reasonable and necessary items and services used to diagnose and treat complications arising from participation in all qualifying clinical trials. Qualifying clinical trials include those that are directly funded or supported by centers or cooperating groups funded by the National Institutes of Health (NIH), Centers for Disease Control (CDC), Agency for Healthcare Research and Quality (AHRQ), Department of Defense (DOD), or Veterans Affairs (VA).
Inpatient Hospital Services
The following are coverage rules for specific inpatient hospital services. Inpatient hospital services included in the All Patient Refined Diagnosis-Related Group (APR-DRG) payment methodology include all routine services such as the following:
Abortions (ARM 37.86.104)
Abortions are covered when one of the following conditions are met:
A completed Montana Healthcare Programs Physician Certification for Abortion Services (MA-37) form must be submitted with every abortion claim or payment will be denied. Complete only one section of this form. This form is the only form Montana Healthcare Programs accepts for abortion services.
When using mifepristone (Mifeprex or RU 486) to terminate a pregnancy, it must be administered within 49 days from the beginning of the last menstrual period by or under the supervision of a physician who:
Air Transports
Air transport providers must be registered with Montana Healthcare Programs as an ambulance provider. Claims for these services are billed on a CMS-1500 claim form. See the Ambulance Services manual available on the Provider Information website.
Chemical Dependency Treatment
Chemical dependency services are limited. Providers must be approved by the Department before providing this service. Contact the Chemical Dependency Bureau for information. (See the Contact Us link on the Provider Information website.)
Discharges
A hospital’s utilization review (UR) committee must comply with the Code of Federal Regulations 42 CFR 456.131 through 42 CFR 456.137 prior to notifying a Montana Healthcare Programs member that he/she no longer needs medical care. The hospital is not required to obtain approval from Montana Healthcare Programs at the member’s discharge; however, a hospital’s UR plan must provide written notice to Montana Healthcare Programs if a member decides to stay in the hospital when it is not medically necessary. (See the Hospital Services Beyond Medical Necessity section in the Billing Procedures chapter of this manual.)
Donor Transplants
Montana Healthcare Programs covers successful donor-related testing and services and organ acquisition services, which are bundled into the Montana Healthcare Programs member’s transplant hospitalization, and are covered in this APR-DRG payment.
Emergency Department Admissions
Emergency medical services are those services required to evaluate, treat and stabilize an emergency medical condition.
Mental Health Services
Montana Healthcare Programs covers inpatient mental health services for Montana Healthcare Programs-enrolled members when prior authorized. (See the Prior Authorization chapter in this manual. and refer to the mental health manual available on the Provider Information website.)
Observation Bed
Members in observation beds (admission of 72 hours or less) are considered outpatients and claims should be filed accordingly. (See the Hospital Outpatient Services manual available on the Provider Information website.)
Out-of-State Inpatient Services (ARM 37.86.2801)
Montana Healthcare Programs covers treatment in an out-of-state facility only when all of the following requirements are met:
It is not the intent of the Montana Healthcare Programs to interfere or delay a transfer when a physician has determined a situation to be emergent. Prior authorization is not required in emergency situations. Emergency inpatient admissions must be authorized within 2 working days (Monday–Friday) of admission to an out-of-state hospital.
If a hospital that is located over 100 miles outside of the borders of Montana or a Center for Excellence hospital fails to obtain prior authorization before providing services to a Montana Healthcare Programs member, retrospective authorization may be granted under the following circumstances only: The person to whom services were provided was determined by the Department to be retrospectively eligible for Montana Healthcare Programs benefits;
Readmissions (ARM 37.86.2918)
All readmissions are subject to review for medical necessity of the initial stay as well as the subsequent hospitalization stay. Reimbursement cannot be made to a provider unless the service provided was medically necessary. Readmission may be reviewed on a retrospective basis to determine if additional payment for the case is warranted. If complications have arisen because of premature discharge and/or other treatment errors, then the APR-DRG payment for the first admission must be combined with the current admission before billing Montana Healthcare Programs. If the readmission is for the treatment of conditions that could or should have been treated during the previous admission, the two admissions must be combined into one admission for payment purposes.
A member readmission occurring in an inpatient rehabilitation hospital or distinct part unit three days after the initial date of discharge must be combined into one admission for payment purposes, with the exception of discharge to an acute care hospital for surgical APR-DRGs. Inpatient readmissions within 24 hours must be combined if the same condition is coded.
Same Day Readmission
If a member is readmitted on the same day of discharge for the same condition, the entire stay must be billed as one admission.
If a member is readmitted on the same day of discharge for a separate condition, Montana Healthcare Programs may be billed for the new condition. The claim for the new condition and a letter of explanation including documentation for the separate condition must be sent directly to the Hospital Program Officer for review.
A member readmission occurring in an inpatient rehabilitation hospital or distinct part unit three days after the initial date of discharge must be combined into one admission for payment purposes, with the exception of discharge to an acute care hospital for surgical APR-DRGs. Inpatient readmissions within 24 hours must be combined if the same condition is coded.
Sterilization (ARM 37.86.104)
Elective Sterilization
Elective sterilizations are sterilizations done for the purpose of becoming sterile. Montana Healthcare Programs covers elective sterilization for men and women when all of the following requirements are met:
The 30-day waiting period may be waived for either of the following reasons:
All forms required for sterilizations can be downloaded from the Provider Information website,
Before performing a sterilization, the following requirements must be met:
Informed consent for sterilization may not be obtained under the following circumstances:
Medically Necessary Sterilization
When sterilization results from a procedure performed to address another medical problem, it is considered a medically necessary sterilization. These procedures include hysterectomies, oophorectomies, salpingectomies and orchiectomies. Every claim submitted to Montana Healthcare Programs for a medically necessary sterilization must be accompanied by one of the following:
When submitting claims for retroactively eligible members, attach a copy of the 160-M to the claim if the date of service is more than 12 months earlier than the date the claim is submitted.
Transfers (ARM 37.86.2918)
All diagnostic services are included in the APR-DRG payment. Diagnostic services that are performed at a second APR-DRG hospital, because the services are not available at the first hospital (e.g., a CT scan), are included in the first hospital’s APR-DRG payment. This includes transportation to the second hospital and back to the first hospital. Arrangement for payment to the transportation provider and the second hospital where the services were actually performed must be between the first and second hospital and the transportation provider.
All transfers are subject to review for medical necessity. The initial hospitalization, all subsequent hospitalizations, and the medical necessity for the transfer itself may be reviewed. For information on billing and payment for transfers, see this manual’s Billing Procedures and How Payment Is Calculated chapters.
Transplants (ARM 37.86.4701–ARM 37.86.4706)
Montana Healthcare Programs covers organ and tissue transplants that are medically necessary and not considered experimental or investigational. Organ transplants must be performed in a Medicare-certified facility. If Medicare has not designated a facility as being certified, the transplant must be performed by a program located in a hospital or parts of a hospital certified by the Organ Procurement and Transplantation Network (OPTN) for the specific organ being transplanted. A list of CMS-certified facilities is on the CMS website at http://www.cms.hhs.gov. (Search for transplant program certification.)
Organ and tissue transplantation includes the transplant surgery and those activities directly related to the transplantation. These activities may include:
These activities are covered by Montana Healthcare Programs as long as the member remains Montana Healthcare Programs-eligible and transplantation is prior approved. Services must comply with Medicare coverage guidelines for organ and tissue transplant services. If Medicare coverage guidelines are not available, the Department or their designated review organization will review the requested transplant surgery to determine if the surgery is experimental or investigational.
The following medical and nonmedical services, except as otherwise specified in program-specific rules as a waiver service or an EPSDT service, are explicitly excluded from the Montana Healthcare Programs, except for those services specifically available, as listed in ARM 37.40.1406, 37.90.402, and Title 37, Chapter 34, Subchapter 9, to persons eligible for home and community-based services; and except for those Medicare-covered services as listed in ARM 37.83.812 to qualified Medicare beneficiaries for whom the Montana Healthcare Programs pays the
Medicare premiums, deductible, and coinsurance.
End of Covered Services Chapter
Prior authorization is the approval process required before certain services are paid by Montana Healthcare Programs. If a service requires prior authorization, the requirement exists for all Montana Healthcare Programs members. When prior authorization is granted, the provider is issued a prior authorization number, which must be on the claim.
Distinct authorization numbers are issued for Passport approval and prior authorization, and both must be recorded on the claim in the appropriate location.
Prior authorization is not a guarantee of payment. When requesting prior authorization, keep in mind the following:
Montana Healthcare Programs does not pay for services when prior authorization or Passport requirements are not met.
Prior authorization is not required in emergency situations.
It is not the intent of the Montana Healthcare Program to interfere or delay a transfer when a physician has determined a situation to be emergent. Prior authorization is not required in emergency situations. Emergency inpatient admissions must be authorized within three working days (Monday–Friday) of admission to an out-of-state hospital.
Retrospective authorization may be granted only under the following circumstances:
For more information, see the Prior Authorization chapter in the General Information for Providers manual, fee schedules, and the Prior Authorization Information page on the Provider Information website.
End of Prior Authorization Chapter
Services provided by the healthcare professionals covered in this manual must be billed either electronically or on UB-04 claim forms, which are available from various publishing companies; they are not available from the Department or Provider Relations.
The Montana Healthcare Programs member who chooses to remain in the hospital beyond the period of medical necessity may choose to pay for continued inpatient care as a Montana Healthcare Programs noncovered service. The member must have been informed in writing and agreed in writing prior to provision of services to accept financial responsibility. The agreement must state the specific services the Montana Healthcare Programs member has agreed to pay for. In this case, a routine agreement will not suffice. Montana Healthcare Programs may not be billed for hospital services that are not medically necessary.
A hospital’s utilization review plan must provide written notice to Montana Healthcare Programs if a Montana Healthcare Programs member decides to stay in the hospital when it is not medically necessary. This written notice must be sent to the hospital program officer. (See Key Contacts in this manual or the Contact Us link in the left menu on the Provider Information website.)
Effective for all claims paid on or after January 1, 2020 copayment will not be assessed.
Medicare crossovers are claims for hospital patients who are eligible for Medicare Part A benefits and Montana Healthcare Programs. For these members, Montana Healthcare Programs pays the deductibles and coinsurance related to the inpatient hospital services. Should a Medicare/Montana Healthcare Programs member exhaust the Medicare benefit (including Lifetime Reserve Days), the claim will be treated as a Montana Healthcare Programs-only claim from the date the Medicare benefits were exhausted. The claim should be submitted reflecting a covered stay from the day the Medicare benefits were exhausted to discharge. This situation is the only instance in which a hospital should submit a split bill for a case that will be paid using prospective payment principles.
A Montana Healthcare Programs member covered by the Passport to Health program must have inpatient hospital services approved by the member’s primary care provider (PCP). The Passport provider number must be on the claim or the service will be denied.
Prior authorization is required for some hospital services. Passport and prior authorization are different, and some services may require both. See the Passport chapter in the General Information for Providers manual and/or the Prior Authorization chapter in this manual and the Prior Authorization Information page of the Provider Information website. Different codes are issued for each type of approval and must be included on the claim form, or the claim will be denied. See the Submitting a Claim chapter in this manual.
Claims can be filed only after the member has been discharged. A member is considered discharged when he or she is:
The hospital that ultimately discharges the member bills Montana Healthcare Programs. When a member is transferred from one hospital to another for services the first hospital does not provide (e.g., CT scan) and then back to the first hospital, all diagnostic services are included in the APR-DRG payment to the first hospital. Also included in the same payment are the services that were provided at the second hospital and transportation to the second hospital and back to the first hospital. Arrangement for payment to the transportation provider and the second hospital must be arranged between the first and second hospital and the transportation provider.
Providers must notify the Department when a member chooses to stay in the hospital when it is not medically necessary.
All transfers are subject to review for medical necessity. Initial hospitalizations, subsequent hospitalizations, and transfers may be reviewed for medical necessity. Reimbursement cannot be made to a provider unless the service provided was medically necessary.
The patient status code should contain the appropriate discharge status code. The following discharge status codes are valid for Montana Healthcare Programs.
01 Discharged to home or self-care (routine discharge)
02 Discharge/Transfer to another short-term general hospital for inpatient care
03 Discharge/Transfer to skilled nursing facility (SNF)
04 Discharge/Transfer to an intermediate care facility (ICF)
05 Discharge/Transfer to another type of institution for inpatient care
06 Discharge/Transfer to home under care of organized home health service organization
07 Left against medical advice or discontinued care
08 Discharge/Transfer to home under care of a Home IV provider
09 Admitted as an inpatient to this hospital 63 Discharge/Transfer to a long-term care hospital
20 Expired (death) 64 Discharge/Transfer to nursing facility certified under Montana Healthcare Programs, but not Medicare
30 Still a patient (Neonate providers discharge status code for interim billing.)
40 Expired (death) at home
41 Expired in a medical facility (e.g., hospital, SNF, ICF, or free standing hospice)
42 Expired – place unknown
43 Discharge/Transfer to Federal hospital
50 Hospice – home
51 Discharge/Transfer to hospice medical facility
61 Discharge/Transfer within this institution to hospital-based Medicare-approved swing bed
62 Discharge/Transfer to another rehabilitation facility including rehabilitation distinct part units of a hospital
63 Discharge/Transfer to a long-term care hospital
64 Discharge/Transfer to nursing facility certified under Montana Healthcare Programs, but not Medicare
65 Discharge/Transfer to a psychiatric hospital or psychiatric distinct part unit of a hospital
Services that are included in the APR-DRG payment are considered bundled and include the following:
Always refer to the long descriptions in coding books.
Services that are not included in the APR-DRG payment and can be billed separately include the following:
Some inpatient hospital services necessitate the use of split or interim bills for Montana Healthcare Programs reimbursement. In general, providers cannot split bill APR-DRG claims, except in a few cases:
Partial Eligibility
APR-DRG hospitals do not split bill. Bill the entire claim from the date of admit, and the claim will be prorated during processing.
Incurment
All APR-DRG hospitals must bill from the date of admission. For more information on incurment, see the Member Eligibility and Responsibilities chapter in the General Information for Providers manual.
In order to be covered by Montana Healthcare Programs, abortions and sterilizations require specific forms to be completed and submitted with the claim. For more information on abortion and sterilization requirements, see the Covered Services chapter in this manual. Forms are available on the Provider Information website.
Abortions
A completed Montana Healthcare Programs Physician Certification for Abortion Services (MA-37) form must be attached to every abortion claim or payment will be denied. Complete only one part of this form. This is the only form Montana Healthcare Programs accepts for abortions.
Sterilization
When billing for retroactively eligible members, attach a copy of the 160-M to the claim if the date of service is more than 12 months earlier than the date the claim is submitted. For more information, see the Covered Services chapter in this manual.
Providers should use the most specific HCPCS code when billing a service or procedure to enable proper reimbursement. In the event an unlisted service or procedure code must be used, Montana Healthcare Programs urges providers to send medical records with the claim. Reviewing the medical records with the claim allows the claims processing personnel to understand the situation and apply appropriate reimbursement, as well as decreases claims processing time. Medical records can be sent with electronic claims through the use of the paperwork attachment.
When submitting claims that require additional supporting documentation, the Attachment Control Number field must be populated with an identifier. Identifier formats can be designed by software vendors or clearinghouses, but the preferred method is the provider's Montana Healthcare Programs ID number followed by the member's ID number and the date of service, each separated by a dash.
The supporting documentation must be submitted with a Paperwork Attachment Cover Sheet. The number in the paper Attachment Control Number field must match the number on the cover sheet.
End Billing Procedures Chapter
The services described in this manual are billed on UB-04 claim forms. Use this chapter with the UB-04 claim instructions on the Provider Information website.
Claims submitted with all of the necessary information are referred to as clean and are usually paid in a timely manner. (See the Billing Procedures chapter in the General Information for Providers manual.)
Field 7 is used for cost Passport referral number and sharing indicators. See the table below and UB-04 claim instructions on the Provider Information website.
Code - Used When Providing
FPS - Family planning services
OBS - Obstetrical services
TCM - Targeted case management services
The present on admission (POA) indicator is required for all inpatient claims. The claim will deny if there is no valid POA indicator for each diagnosis. Valid values for POA are:
Y = Present at the time of inpatient admission
N = Not present at the time of inpatient admission
U = Documentation is insufficient to determine whether condition is present on admission.
W = Provider is unable to clinically determine whether condition was present on admission.
End Submitting a Claim Chapter
Though providers do not need the information in this chapter to submit claims to the Department, the information allows providers to understand how payment is calculated and to predict approximate payment for particular claims.
Several methods of payment are used for inpatient hospital services. These include prospective payment using the All Patient Refined Diagnosis-Related Group (APR-DRG), cost-based payment that is retrospectively adjusted at the end of a reporting period and payment based on a percentage of allowed charges.
For most cases, payment equals the relative weight for the APR-DRG times the base price plus the applicable additive factors, such as cost outliers and disproportionate share hospital payment. The overall method is patterned after similar payment policies used by Medicare. When specific details of the payment method differ between Medicare and Montana Healthcare Programs, then the Montana Healthcare Programs policy prevails. Hospitals are not required to purchase grouping software and need not indicate the APR-DRG on the claim.
Upon the discharge or transfer of each member, hospitals submit a claim to Montana Healthcare Programs. The Department reimburses hospitals a per-stay rate based on All Patient Refined Diagnosis Related Groups (APR-DRGs). The claim will provide, among other information, the member’s principal diagnosis, additional diagnoses, principal and secondary procedures, age, sex and discharge status. These variables are passed through an APR-DRG grouper program to determine the appropriate APR-DRG for each discharge. Although hospitals may indicate the anticipated APR-DRG on the billing invoice, the Montana Healthcare Programs grouper program is the final determinant in assigning the payable APR-DRG to each case. Interim billing is only allowed in specific situations noted in this chapter.
After Montana Healthcare Programs has determined the allowed payment amount, that amount is reduced by any reported third party liability (TPL) amount, cost share amount, Medicare Part A payment amount and member responsibility (Incurment), then Montana Healthcare Programs pays the remainder.
Hospitals reimbursed using the inpatient prospective payment method are not subject to retrospective cost reimbursement.
Claims may sometimes deny for an ungroupable DRG, which is an error in DRG assignment. These errors occur when an invalid or non-existent ICD code is used. Providers should use the ICD codes applicable to the member’s dates of service. For claims that deny due to an ungroupable DRG, providers should re-code thee claim to a more specific and accurate code for the service provided.
APR-DRG Relative Weights
For each APR-DRG, a relative weight factor is assigned. The relative weight is applied to determine the APR-DRG Base Payment that will be paid for each admit-through-discharge case regardless of the specific services provided or the length of stay. The APR-DRG relative weight is a weight assigned that reflects the typical resources consumed.
APR-DRG weights are reviewed and updated periodically by the Department. The weights are adapted from national databases of millions of inpatient stays and are then “re-centered” so that the average Montana Healthcare Programs stay in a base year has a weight of 1.00.
When the Department determines that adjustments to relative weights for specific APR-DRGs are appropriate to meet Montana Healthcare Programs policy goals related to access to quality care, a policy adjustor may be explicitly applied to increase or decrease these relative weights. Policy adjustors are intended to be budget neutral, that is, they change payments for one type of service relative to other types without increasing or decreasing payments overall.
DRG Base Price
There are two different base prices for stays in acute care hospitals and Center of Excellence hospitals. The base price is a dollar amount that is reviewed by the Department each year. Changes in the APR-DRG Base Price are subject to the public notice requirements of the Montana Code Annotated.
APR-DRG Base Payment
For each stay, the DRG Base Payment equals the DRG Relative Weight multiplied by the DRG Base Price.
The posted APR-DRG Fee Schedule contains all of the above information.
Capital Related Costs
Capital cost is included in the DRG-based payment and will not be paid separately.
Cost Outlier Payments
It is recognized that there are occasional stays that are extraordinarily costly in relation to other stays within the same APR-DRG because of the severity of the illness or complicating conditions. These variations are recognized by the cost outlier payment which is an add-on payment for expenses that are not predictable by the diagnosis, procedures performed, and other statistical data captured by the APR-DRG grouper.
Cost outlier stays are stays that exceed the cost outlier threshold for the APR-DRG. To determine if a hospital stay exceeds the cost outlier threshold, the Montana Healthcare Programs program excludes all services that are not medically necessary. Montana Healthcare Programs then converts the charge information for medical necessary services into the estimated cost of the stay by applying the statewide average PPS inpatient cost-to-charge radio (CCR). The estimated cost for medically necessary services is then compared to the cost outlier threshold for the appropriate APR-DRG to determine if the stay qualifies for reimbursement as a cost outlier. Costs exceeding the threshold are multiplied by a marginal cost ratio to determine the cost outlier payment.
Transfer Payment Adjustments
The transfer payment adjustment applies when a patient is transferred to another acute care hospital. It does not apply when a patient is discharged to a post-acute setting such as a skilled nursing facility. The receiving hospital is not impacted by the transfer payment adjustment unless it transfers the patient to another hospital.
In the transfer payment adjustment, payment is calculated as if the beneficiary were not a transfer, then payment is adjusted. The APR-DRG Gross Payment is divided by the nationwide average length of stay for the assigned APR-DRG to arrive at a per diem amount. The per diem amount is then multiplied by the actual length of stay, except that payment is doubled for the first day to reflect costs related to the admitting process. If the transfer payment adjustment results in an amount greater than the amount without the adjustment, the transfer payment adjustment is disregarded. The cost outlier payment, if applicable, is then added to the APR-DRG base payment, with the transfer adjustment made as needed.
The transfer payment adjustment is not applicable to providers and services that are exempt from the Inpatient Prospective Payment Method.
Prorated Payment Adjustment
When a beneficiary has Montana Healthcare Programs coverage for fewer days than the length of stay, the payment is prorated. The APR-DRG Gross Payment plus cost outlier payments, if applicable, is divided by the nationwide average length of stay for the assigned APR-DRG to arrive at a per diem amount. The per diem amount is then multiplied by the number of days the beneficiary is eligible for Montana Healthcare Programs during the stay. If the prorated payment adjustment results in a payment amount greater than the amount without the adjustment, the prorated payment is disregarded.
The Prorated Payment Adjustment is not applicable to providers and services that are exempt from the Inpatient Prospective Payment Method. See the section titled Exempt Services and Costs.
The Cost-Based Payment Method for Exempt Hospitals and Services
The following providers are exempt from the Inpatient Prospective Payment Method. In the interest of clarity, this list includes acute care hospitals as well as facilities that provide similar inpatient services.
Exempt Services and Costs
The following services are exempt from the Inpatient Prospective Payment method even when provided by hospitals that are otherwise subject to prospective payment.
Reasonable Cost Reimbursement
Hospitals exempt from prospective payment will continue to use the Title XVIII retrospective reasonable cost principals for reimbursing Montana Healthcare Programs inpatient hospitals services. Allowable costs will be determined in accordance with generally accepted accounting principals as defined by the American Institute of Certified Public Accountants. Such definition of allowable costs is further defined in accordance with the Medicare Provider Reimbursement Manual, CMS Pub. 15-1, subject to the exceptions and limitations provided in the Department’s Administrative Rules. Pub. 15 is a manual published by the United States Department of Health and Human Services, CMS, which provides guidelines and policies to implement Medicare regulations which set forth principals for determining the reasonable cost of provider services furnished under the Health Insurance for Aged Act of 1965, as amended.
Hospitals subject to retrospective reasonable cost reimbursement shall receive interim payments weekly or biweekly during the facility’s fiscal year by submitting claims to the Department’s fiscal intermediary. The interim payment rate will be based on a percentage of customary (billed) charges to costs as determined by the facility’s most recently settled Montana Healthcare Programs cost report. If a provider fails to submit financial information to compute the rate, the provider will be reimbursed at 50 percent of its usual and customary billed charges. Hospital providers are required to submit the CMS 2552-96 to the Medicare Fiscal Intermediary (FI) and the Department within five months of their fiscal year end. The FI either audits or desk reviews the cost report, then sends the Department the “as adjusted” cost report. Montana Healthcare Programs settlements are made from the “as adjusted” cost report.
For each hospital that is a critical access hospital, reimbursement for reasonable costs of inpatient hospital services shall be limited to the lesser of 101 percent of allowable costs or the upper payment limit.
Services where Medicare is the primary payer (crossover claims) are not reimbursed using retrospective cost principles. Reimbursement for these services is the remaining coinsurance and deductible. The Department shall reimburse cost-based inpatient hospital service providers for certified registered nurse anesthetists costs on a reasonable cost basis.
Payment for hospital residents will be made as follows:
When a member has coverage from both Montana Healthcare Programs and another insurance company, the other insurance company is often referred to as third party liability (TPL). In these cases, the other insurance is the primary payer, and Montana Healthcare Programs makes a payment as the secondary payer. Montana Healthcare Programs will make a payment only when the TPL payment is less than the Montana Healthcare Programs allowed amount.
When a member has coverage from both Medicare and Montana Healthcare Programs, Medicare is the primary payer. Montana Healthcare Programs will pay the coinsurance and deductible, less any TPL or
incurment, on inpatient hospital claims for these dually eligible individuals.
Member Has Medicare and Montana Healthcare Programs Coverage. A provider submits an inpatient hospital claim for a member with Medicare and Montana Healthcare Programs. The Medicare coinsurance and deductible are $65.00 and $185.00. This total ($250.00) becomes the Montana Healthcare Programs allowed amount. Montana Healthcare Programs will pay this amount ($250.00) as long as no TPL or incurment amounts are applicable.
Member Has Medicare, Montana Healthcare Programs coverage, and TPL. A provider submits an inpatient hospital claim for a member with Medicare, Montana Healthcare Programs, and TPL. The Medicare coinsurance and deductible are $65.00 and $185.00. This total ($250.00) becomes the Montana Healthcare Programs allowed amount. The other insurance company paid $225.00. This amount is subtracted from the Montana Healthcare Programs allowed amount leaving $25.00. Montana Healthcare Programs pays $25.00 for this claim. If the TPL payment had been $250.00 or more, this claim would have paid at $0.00.
Disproportionate Share Hospital (DSH) payments, including routine and supplemental DSH payments, will be limited to the cap established by the Federal Centers for Medicare and Montana Healthcare Programs Services (CMS) for Montana.
Routine DSH shall receive an additional payment amount equal to the product of the hospital’s prospective base rate x the adjustment percent of 4% rural hospital and 10% urban hospitals. All Supplemental Disproportionate Share Hospitals (SDSH) shall receive an SDSH payment. DSH payments will only be given to eligible in-state hospitals.

End Key Contacts Chapter
Thank you for your willingness to serve members of the Montana Healthcare Programs and other medical assistance programs administered by the Department of Public Health and Human Services.
This manual provides information specifically for hospital inpatient services. Other essential information for providers is contained in the separate General Information for Providers manual. Providers are responsible for reviewing both manuals.
A table of contents and an index allow you to quickly find answers to most questions. The margins contain important notes with extra space for writing notes. There is a list of contacts at the beginning of each manual. There is also space on the inside of the front cover to record your NPI for quick reference when calling Provider Relations.
Manuals must be kept current. Changes to manuals are provided through provider notices and replacement pages. Manual replacement pages can be downloaded from the provider type pages on the Provider Information website and are identified by a note at the top of the page indicating Replacement Page and the date. They are designed to be printed on the front and back of each page, so they are always in sets of two beginning with an odd page followed by an even page, even though one of the pages may not have any changes. When replacing a page in a paper manual, file the old pages and provider notices in the back of the manual for use with claims that originated under the old policy.
Providers must be familiar with all current rules and regulations governing the Montana Healthcare Programs. Provider manuals are to assist providers in billing Montana Healthcare Programs; they do not contain all Montana Healthcare Programs rules and regulations. Rule citations in the text are a reference tool; they are not a summary of the entire rule. In the event that a manual conflicts with a rule, the rule prevails. Links to rules are available on the Provider Information website. Paper copies of rules are available through the Secretary of State’s office. See the Contact Us link in the left menu on the Provider Information website.
Providers are responsible for knowing and following current Montana Healthcare Programs rules and regulations.
In addition to the general Montana Healthcare Programs rules outlined in the General Information for Providers manual, the following rules and regulations are also applicable to the hospital inpatient program:
The Department is committed to paying Montana Healthcare Programs providers’ claims as quickly as possible. Montana Healthcare Programs claims are electronically processed and usually are not reviewed by medical experts prior to payment to determine if the services provided were appropriately billed. Although the computerized system can detect and deny some erroneous claims, there are many erroneous claims it cannot detect. For this reason, payment of a claim does not mean the service was correctly billed or the payment made to the provider was correct. Periodic retrospective reviews are performed that may lead to the discovery of incorrect billing or incorrect payment. If a claim is paid and the Department later discovers the service was incorrectly billed or paid or the claim was erroneous in some other way, the Department is required by federal regulation to recover any overpayment, regardless of whether the incorrect payment was the result of Department or provider error or other cause.
The provider manuals are designed to answer most questions; however, questions may arise that require a call to a specific group (such as a program officer, Provider Relations, or a prior authorization unit). A list of key contacts and websites is available online. On the Provider Information website, choose the Contact Us link in the left menu. Providers should also read the monthly Claim Jumper newsletter for Montana Healthcare Programs updates and changes. Montana Healthcare Programs provider manuals, provider notices, replacement pages, fee schedules, forms, and more are available on the Provider Information website.
End of Introduction Chapter
Montana Healthcare Programs covers inpatient hospital services when they are medically necessary. This chapter provides covered services information that applies specifically to inpatient hospital services. Like all healthcare services received by Montana Healthcare Programs members, these services must also meet the general requirements listed in the Provider Requirements chapter of the General Information for Providers manual.
Hospital Inpatient Services (ARM 37.86.2801–2950)
Inpatient hospital services are provided to Montana Healthcare Programs members who are formally admitted as an inpatient and whose expected hospital stay is greater than 24 hours. Inpatient services must be ordered by a licensed physician or dentist and provided in an institution maintained primarily for treatment and care of patients with disorders other than tuberculosis or mental diseases. The institution must be currently licensed by the designated state licensing authority in the state where the institution is located, must meet the requirements for participation in Medicare as a hospital, and must have in effect a utilization review plan that meets the requirements of 42 CFR 482.30.
Services for Children (ARM 37.86.2201–2235)
The Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) Services program is a comprehensive approach to healthcare for Montana Healthcare Programs members ages 20 and under. It is designed to prevent, identify, and then treat health problems before they become disabling. Under EPSDT, Montana Healthcare Programs eligible children may receive any medically necessary covered service, including all inpatient hospital services described in this manual. All applicable Passport to Health and prior authorization requirements apply.
Importance of Fee Schedules
The easiest way to verify coverage for a specific service is to check the Department’s fee schedule for your provider type. In addition to being listed on the fee schedule, all services provided must also meet the coverage criteria listed in the Provider Requirements chapter of the General Information for Providers manual and in this chapter. Use the fee schedule in conjunction with the more detailed coding descriptions listed in the current ICD coding book. Take care to use the fee schedule and coding books that pertain to the date of service. Fee schedules are available on the Provider Information website.
At the time a claim is submitted, the hospital must have on file a signed and dated acknowledgment from the attending physician that the physician has received the following notice:
Notice to physicians: Montana Healthcare Programs payment to hospitals is based on all of each patient’s diagnoses and the procedures performed on the patient, as attested to by the patient's attending physician by virtue of his or her signature in the medical record. Anyone who misrepresents, falsifies or conceals essential information required for payment of federal funds, may be subject to fine, imprisonment or civil penalty under applicable federal laws.
The acknowledgement must be completed by the physician at the time that the physician is granted admitting privileges at the hospital, or before or at the time the physician admits his/her first member to the hospital. Existing acknowledgments signed by physicians already on staff remain in effect as long as the physician has admitting privileges at the hospital. The provider may, at its discretion, add to the language of this statement the word Medicare so that two separate forms will not be required by the provider to comply with state and federal requirements.
The Department or its contractor may at any time review paid claims, provider documentation for medical necessity, appropriate billing, etc. Providers must maintain documentation of medical necessity for services such as initial hospitalization, transfers, and readmissions. For more information on provider requirements for maintaining documentation, see the Record Keeping section in the Provider Requirements chapter of the General Information for Providers manual. Also see the Claims Review section in the Introduction chapter of this manual.
Providers must contact the Department to obtain hospital residence status prior to billing Montana Healthcare Programs. To qualify for residency status, a member must meet the following requirements:
It is the provider’s responsibility to determine whether services could be provided in a skilled nursing care facility or by the Home and Community-Based Waiver Program. The provider must maintain written records of inquiries and responses about the present and future availability of openings in nursing facilities and the Home and Community-Based Waiver Program. A redetermination of nursing facility or waiver availability must be made at least every 6 months.
Hospitalized Montana Healthcare Programs members and Montana Healthcare Programs applicants being considered for nursing facility placement from the hospital shall be referred in a timely manner to the preadmission screening team. The preadmission screening form (Form DPHHS-SLTC-61) must be completed before placement and payment is made on their behalf.
Elective Deliveries
Effective July 1, 2014, all facilities must have a hard-stop policy in place regarding non-medically necessary inductions prior to 39 weeks and nonmedically necessary Cesarean sections at any gestational age. The policy must contain the following:
Effective October 1, 2014, Montana Healthcare Programs will reduce reimbursement rates for non-medically necessary inductions prior to 39 weeks, and non-medically necessary Cesarean sections at any gestational ages. All hospital claims with an admit date on or after October 1, 2014, will require coding changes to delivery claims.
Hospital inpatient claims and birthing center claims will require the use of condition codes for all induction and Cesarean section deliveries. These claims will be reviewed for medical necessity based on an approved list of diagnosis codes. The condition codes are:
Clinical Trials (ARM 37.86.2902)
Clinical trial drugs, devices, and procedures are not reimbursable. Clinical trials are limited to Montana Healthcare Programs coverage of routine costs plus reasonable and necessary items and services used to diagnose and treat complications arising from participation in all qualifying clinical trials. Qualifying clinical trials include those that are directly funded or supported by centers or cooperating groups funded by the National Institutes of Health (NIH), Centers for Disease Control (CDC), Agency for Healthcare Research and Quality (AHRQ), Department of Defense (DOD), or Veterans Affairs (VA).
Inpatient Hospital Services
The following are coverage rules for specific inpatient hospital services. Inpatient hospital services included in the All Patient Refined Diagnosis-Related Group (APR-DRG) payment methodology include all routine services such as the following:
Abortions (ARM 37.86.104)
Abortions are covered when one of the following conditions are met:
A completed Montana Healthcare Programs Physician Certification for Abortion Services (MA-37) form must be submitted with every abortion claim or payment will be denied. Complete only one section of this form. This form is the only form Montana Healthcare Programs accepts for abortion services.
When using mifepristone (Mifeprex or RU 486) to terminate a pregnancy, it must be administered within 49 days from the beginning of the last menstrual period by or under the supervision of a physician who:
Air Transports
Air transport providers must be registered with Montana Healthcare Programs as an ambulance provider. Claims for these services are billed on a CMS-1500 claim form. See the Ambulance Services manual available on the Provider Information website.
Chemical Dependency Treatment
Chemical dependency services are limited. Providers must be approved by the Department before providing this service. Contact the Chemical Dependency Bureau for information. (See the Contact Us link on the Provider Information website.)
Discharges
A hospital’s utilization review (UR) committee must comply with the Code of Federal Regulations 42 CFR 456.131 through 42 CFR 456.137 prior to notifying a Montana Healthcare Programs member that he/she no longer needs medical care. The hospital is not required to obtain approval from Montana Healthcare Programs at the member’s discharge; however, a hospital’s UR plan must provide written notice to Montana Healthcare Programs if a member decides to stay in the hospital when it is not medically necessary. (See the Hospital Services Beyond Medical Necessity section in the Billing Procedures chapter of this manual.)
Donor Transplants
Montana Healthcare Programs covers successful donor-related testing and services and organ acquisition services, which are bundled into the Montana Healthcare Programs member’s transplant hospitalization, and are covered in this APR-DRG payment.
Emergency Department Admissions
Emergency medical services are those services required to evaluate, treat and stabilize an emergency medical condition.
Mental Health Services
Montana Healthcare Programs covers inpatient mental health services for Montana Healthcare Programs-enrolled members when prior authorized. (See the Prior Authorization chapter in this manual. and refer to the mental health manual available on the Provider Information website.)
Observation Bed
Members in observation beds (admission of 72 hours or less) are considered outpatients and claims should be filed accordingly. (See the Hospital Outpatient Services manual available on the Provider Information website.)
Out-of-State Inpatient Services (ARM 37.86.2801)
Montana Healthcare Programs covers treatment in an out-of-state facility only when all of the following requirements are met:
It is not the intent of the Montana Healthcare Programs to interfere or delay a transfer when a physician has determined a situation to be emergent. Prior authorization is not required in emergency situations. Emergency inpatient admissions must be authorized within 2 working days (Monday–Friday) of admission to an out-of-state hospital.
If a hospital that is located over 100 miles outside of the borders of Montana or a Center for Excellence hospital fails to obtain prior authorization before providing services to a Montana Healthcare Programs member, retrospective authorization may be granted under the following circumstances only: The person to whom services were provided was determined by the Department to be retrospectively eligible for Montana Healthcare Programs benefits;
Readmissions (ARM 37.86.2918)
All readmissions are subject to review for medical necessity of the initial stay as well as the subsequent hospitalization stay. Reimbursement cannot be made to a provider unless the service provided was medically necessary. Readmission may be reviewed on a retrospective basis to determine if additional payment for the case is warranted. If complications have arisen because of premature discharge and/or other treatment errors, then the APR-DRG payment for the first admission must be combined with the current admission before billing Montana Healthcare Programs. If the readmission is for the treatment of conditions that could or should have been treated during the previous admission, the two admissions must be combined into one admission for payment purposes.
A member readmission occurring in an inpatient rehabilitation hospital or distinct part unit three days after the initial date of discharge must be combined into one admission for payment purposes, with the exception of discharge to an acute care hospital for surgical APR-DRGs. Inpatient readmissions within 24 hours must be combined if the same condition is coded.
Same Day Readmission
If a member is readmitted on the same day of discharge for the same condition, the entire stay must be billed as one admission.
If a member is readmitted on the same day of discharge for a separate condition, Montana Healthcare Programs may be billed for the new condition. The claim for the new condition and a letter of explanation including documentation for the separate condition must be sent directly to the Hospital Program Officer for review.
A member readmission occurring in an inpatient rehabilitation hospital or distinct part unit three days after the initial date of discharge must be combined into one admission for payment purposes, with the exception of discharge to an acute care hospital for surgical APR-DRGs. Inpatient readmissions within 24 hours must be combined if the same condition is coded.
Sterilization (ARM 37.86.104)
Elective Sterilization
Elective sterilizations are sterilizations done for the purpose of becoming sterile. Montana Healthcare Programs covers elective sterilization for men and women when all of the following requirements are met:
The 30-day waiting period may be waived for either of the following reasons:
All forms required for sterilizations can be downloaded from the Provider Information website,
Before performing a sterilization, the following requirements must be met:
Informed consent for sterilization may not be obtained under the following circumstances:
Medically Necessary Sterilization
When sterilization results from a procedure performed to address another medical problem, it is considered a medically necessary sterilization. These procedures include hysterectomies, oophorectomies, salpingectomies and orchiectomies. Every claim submitted to Montana Healthcare Programs for a medically necessary sterilization must be accompanied by one of the following:
When submitting claims for retroactively eligible members, attach a copy of the 160-M to the claim if the date of service is more than 12 months earlier than the date the claim is submitted.
Transfers (ARM 37.86.2918)
All diagnostic services are included in the APR-DRG payment. Diagnostic services that are performed at a second APR-DRG hospital, because the services are not available at the first hospital (e.g., a CT scan), are included in the first hospital’s APR-DRG payment. This includes transportation to the second hospital and back to the first hospital. Arrangement for payment to the transportation provider and the second hospital where the services were actually performed must be between the first and second hospital and the transportation provider.
All transfers are subject to review for medical necessity. The initial hospitalization, all subsequent hospitalizations, and the medical necessity for the transfer itself may be reviewed. For information on billing and payment for transfers, see this manual’s Billing Procedures and How Payment Is Calculated chapters.
Transplants (ARM 37.86.4701–ARM 37.86.4706)
Montana Healthcare Programs covers organ and tissue transplants that are medically necessary and not considered experimental or investigational. Organ transplants must be performed in a Medicare-certified facility. If Medicare has not designated a facility as being certified, the transplant must be performed by a program located in a hospital or parts of a hospital certified by the Organ Procurement and Transplantation Network (OPTN) for the specific organ being transplanted. A list of CMS-certified facilities is on the CMS website at http://www.cms.hhs.gov. (Search for transplant program certification.)
Organ and tissue transplantation includes the transplant surgery and those activities directly related to the transplantation. These activities may include:
These activities are covered by Montana Healthcare Programs as long as the member remains Montana Healthcare Programs-eligible and transplantation is prior approved. Services must comply with Medicare coverage guidelines for organ and tissue transplant services. If Medicare coverage guidelines are not available, the Department or their designated review organization will review the requested transplant surgery to determine if the surgery is experimental or investigational.
The following medical and nonmedical services, except as otherwise specified in program-specific rules as a waiver service or an EPSDT service, are explicitly excluded from the Montana Healthcare Programs, except for those services specifically available, as listed in ARM 37.40.1406, 37.90.402, and Title 37, Chapter 34, Subchapter 9, to persons eligible for home and community-based services; and except for those Medicare-covered services as listed in ARM 37.83.812 to qualified Medicare beneficiaries for whom the Montana Healthcare Programs pays the
Medicare premiums, deductible, and coinsurance.

Many services require prior authorization before they may be provided. These requirements have been established after consultation with the Department’s DUR Board. Criteria listed for each therapy are derived from reviews completed by the University of Montana’s School of Pharmacy and approved by the DUR Board. Prior Authorization requests are reviewed for medical necessity. When seeking prior authorization, keep in mind the following:
When submitting claims for retroactively eligible members in which the date of service is more than 12 months earlier than the date the claim is submitted, attach a copy of the Provider Notice of Eligibility (Form 160-M). To obtain Form 160-M the provider needs to contact the member’s local Office of Public Assistance and request the form. For a list of local Offices of Public Assistance, see the DPHHS website, https://dphhs.mt.gov/hcsd/OfficeofPublicAssistance.

Contact the Prior Authorization Unit. See Key Contacts.
End of Prior Authorization Chapter
Services provided by the healthcare professionals covered in this manual must be billed either electronically or on UB-04 claim forms, which are available from various publishing companies; they are not available from the Department or Provider Relations.
The Montana Healthcare Programs member who chooses to remain in the hospital beyond the period of medical necessity may choose to pay for continued inpatient care as a Montana Healthcare Programs noncovered service. The member must have been informed in writing and agreed in writing prior to provision of services to accept financial responsibility. The agreement must state the specific services the Montana Healthcare Programs member has agreed to pay for. In this case, a routine agreement will not suffice. Montana Healthcare Programs may not be billed for hospital services that are not medically necessary.
A hospital’s utilization review plan must provide written notice to Montana Healthcare Programs if a Montana Healthcare Programs member decides to stay in the hospital when it is not medically necessary. This written notice must be sent to the hospital program officer. (See Key Contacts in this manual or the Contact Us link in the left menu on the Provider Information website.)
Effective for all claims paid on or after January 1, 2020 copayment will not be assessed.
Medicare crossovers are claims for hospital patients who are eligible for Medicare Part A benefits and Montana Healthcare Programs. For these members, Montana Healthcare Programs pays the deductibles and coinsurance related to the inpatient hospital services. Should a Medicare/Montana Healthcare Programs member exhaust the Medicare benefit (including Lifetime Reserve Days), the claim will be treated as a Montana Healthcare Programs-only claim from the date the Medicare benefits were exhausted. The claim should be submitted reflecting a covered stay from the day the Medicare benefits were exhausted to discharge. This situation is the only instance in which a hospital should submit a split bill for a case that will be paid using prospective payment principles.
A Montana Healthcare Programs member covered by the Passport to Health program must have inpatient hospital services approved by the member’s primary care provider (PCP). The Passport provider number must be on the claim or the service will be denied.
Prior authorization is required for some hospital services. Passport and prior authorization are different, and some services may require both. See the Passport chapter in the General Information for Providers manual and/or the Prior Authorization chapter in this manual and the Prior Authorization Information page of the Provider Information website. Different codes are issued for each type of approval and must be included on the claim form, or the claim will be denied. See the Submitting a Claim chapter in this manual.
Claims can be filed only after the member has been discharged. A member is considered discharged when he or she is:
The hospital that ultimately discharges the member bills Montana Healthcare Programs. When a member is transferred from one hospital to another for services the first hospital does not provide (e.g., CT scan) and then back to the first hospital, all diagnostic services are included in the APR-DRG payment to the first hospital. Also included in the same payment are the services that were provided at the second hospital and transportation to the second hospital and back to the first hospital. Arrangement for payment to the transportation provider and the second hospital must be arranged between the first and second hospital and the transportation provider.
Providers must notify the Department when a member chooses to stay in the hospital when it is not medically necessary.
All transfers are subject to review for medical necessity. Initial hospitalizations, subsequent hospitalizations, and transfers may be reviewed for medical necessity. Reimbursement cannot be made to a provider unless the service provided was medically necessary.
The patient status code should contain the appropriate discharge status code. The following discharge status codes are valid for Montana Healthcare Programs.
01 Discharged to home or self-care (routine discharge)
02 Discharge/Transfer to another short-term general hospital for inpatient care
03 Discharge/Transfer to skilled nursing facility (SNF)
04 Discharge/Transfer to an intermediate care facility (ICF)
05 Discharge/Transfer to another type of institution for inpatient care
06 Discharge/Transfer to home under care of organized home health service organization
07 Left against medical advice or discontinued care
08 Discharge/Transfer to home under care of a Home IV provider
09 Admitted as an inpatient to this hospital 63 Discharge/Transfer to a long-term care hospital
20 Expired (death) 64 Discharge/Transfer to nursing facility certified under Montana Healthcare Programs, but not Medicare
30 Still a patient (Neonate providers discharge status code for interim billing.)
40 Expired (death) at home
41 Expired in a medical facility (e.g., hospital, SNF, ICF, or free standing hospice)
42 Expired – place unknown
43 Discharge/Transfer to Federal hospital
50 Hospice – home
51 Discharge/Transfer to hospice medical facility
61 Discharge/Transfer within this institution to hospital-based Medicare-approved swing bed
62 Discharge/Transfer to another rehabilitation facility including rehabilitation distinct part units of a hospital
63 Discharge/Transfer to a long-term care hospital
64 Discharge/Transfer to nursing facility certified under Montana Healthcare Programs, but not Medicare
65 Discharge/Transfer to a psychiatric hospital or psychiatric distinct part unit of a hospital
Services that are included in the APR-DRG payment are considered bundled and include the following:
Always refer to the long descriptions in coding books.
Services that are not included in the APR-DRG payment and can be billed separately include the following:
Some inpatient hospital services necessitate the use of split or interim bills for Montana Healthcare Programs reimbursement. In general, providers cannot split bill APR-DRG claims, except in a few cases:
Partial Eligibility
APR-DRG hospitals do not split bill. Bill the entire claim from the date of admit, and the claim will be prorated during processing.
Incurment
All APR-DRG hospitals must bill from the date of admission. For more information on incurment, see the Member Eligibility and Responsibilities chapter in the General Information for Providers manual.
In order to be covered by Montana Healthcare Programs, abortions and sterilizations require specific forms to be completed and submitted with the claim. For more information on abortion and sterilization requirements, see the Covered Services chapter in this manual. Forms are available on the Provider Information website.
Abortions
A completed Montana Healthcare Programs Physician Certification for Abortion Services (MA-37) form must be attached to every abortion claim or payment will be denied. Complete only one part of this form. This is the only form Montana Healthcare Programs accepts for abortions.
Sterilization
When billing for retroactively eligible members, attach a copy of the 160-M to the claim if the date of service is more than 12 months earlier than the date the claim is submitted. For more information, see the Covered Services chapter in this manual.
Providers should use the most specific HCPCS code when billing a service or procedure to enable proper reimbursement. In the event an unlisted service or procedure code must be used, Montana Healthcare Programs urges providers to send medical records with the claim. Reviewing the medical records with the claim allows the claims processing personnel to understand the situation and apply appropriate reimbursement, as well as decreases claims processing time. Medical records can be sent with electronic claims through the use of the paperwork attachment.
When submitting claims that require additional supporting documentation, the Attachment Control Number field must be populated with an identifier. Identifier formats can be designed by software vendors or clearinghouses, but the preferred method is the provider's Montana Healthcare Programs ID number followed by the member's ID number and the date of service, each separated by a dash.
The supporting documentation must be submitted with a Paperwork Attachment Cover Sheet. The number in the paper Attachment Control Number field must match the number on the cover sheet.
End Billing Procedures Chapter
The services described in this manual are billed on UB-04 claim forms. Use this chapter with the UB-04 claim instructions on the Provider Information website.
Claims submitted with all of the necessary information are referred to as clean and are usually paid in a timely manner. (See the Billing Procedures chapter in the General Information for Providers manual.)
Field 7 is used for cost Passport referral number and sharing indicators. See the table below and UB-04 claim instructions on the Provider Information website.
Code - Used When Providing
FPS - Family planning services
OBS - Obstetrical services
TCM - Targeted case management services
The present on admission (POA) indicator is required for all inpatient claims. The claim will deny if there is no valid POA indicator for each diagnosis. Valid values for POA are:
Y = Present at the time of inpatient admission
N = Not present at the time of inpatient admission
U = Documentation is insufficient to determine whether condition is present on admission.
W = Provider is unable to clinically determine whether condition was present on admission.
End Submitting a Claim Chapter
Though providers do not need the information in this chapter to submit claims to the Department, the information allows providers to understand how payment is calculated and to predict approximate payment for particular claims.
Several methods of payment are used for inpatient hospital services. These include prospective payment using the All Patient Refined Diagnosis-Related Group (APR-DRG), cost-based payment that is retrospectively adjusted at the end of a reporting period and payment based on a percentage of allowed charges.
For most cases, payment equals the relative weight for the APR-DRG times the base price plus the applicable additive factors, such as cost outliers and disproportionate share hospital payment. The overall method is patterned after similar payment policies used by Medicare. When specific details of the payment method differ between Medicare and Montana Healthcare Programs, then the Montana Healthcare Programs policy prevails. Hospitals are not required to purchase grouping software and need not indicate the APR-DRG on the claim.
Upon the discharge or transfer of each member, hospitals submit a claim to Montana Healthcare Programs. The Department reimburses hospitals a per-stay rate based on All Patient Refined Diagnosis Related Groups (APR-DRGs). The claim will provide, among other information, the member’s principal diagnosis, additional diagnoses, principal and secondary procedures, age, sex and discharge status. These variables are passed through an APR-DRG grouper program to determine the appropriate APR-DRG for each discharge. Although hospitals may indicate the anticipated APR-DRG on the billing invoice, the Montana Healthcare Programs grouper program is the final determinant in assigning the payable APR-DRG to each case. Interim billing is only allowed in specific situations noted in this chapter.
After Montana Healthcare Programs has determined the allowed payment amount, that amount is reduced by any reported third party liability (TPL) amount, cost share amount, Medicare Part A payment amount and member responsibility (Incurment), then Montana Healthcare Programs pays the remainder.
Hospitals reimbursed using the inpatient prospective payment method are not subject to retrospective cost reimbursement.
Claims may sometimes deny for an ungroupable DRG, which is an error in DRG assignment. These errors occur when an invalid or non-existent ICD code is used. Providers should use the ICD codes applicable to the member’s dates of service. For claims that deny due to an ungroupable DRG, providers should re-code thee claim to a more specific and accurate code for the service provided.
APR-DRG Relative Weights
For each APR-DRG, a relative weight factor is assigned. The relative weight is applied to determine the APR-DRG Base Payment that will be paid for each admit-through-discharge case regardless of the specific services provided or the length of stay. The APR-DRG relative weight is a weight assigned that reflects the typical resources consumed.
APR-DRG weights are reviewed and updated periodically by the Department. The weights are adapted from national databases of millions of inpatient stays and are then “re-centered” so that the average Montana Healthcare Programs stay in a base year has a weight of 1.00.
When the Department determines that adjustments to relative weights for specific APR-DRGs are appropriate to meet Montana Healthcare Programs policy goals related to access to quality care, a policy adjustor may be explicitly applied to increase or decrease these relative weights. Policy adjustors are intended to be budget neutral, that is, they change payments for one type of service relative to other types without increasing or decreasing payments overall.
DRG Base Price
There are two different base prices for stays in acute care hospitals and Center of Excellence hospitals. The base price is a dollar amount that is reviewed by the Department each year. Changes in the APR-DRG Base Price are subject to the public notice requirements of the Montana Code Annotated.
APR-DRG Base Payment
For each stay, the DRG Base Payment equals the DRG Relative Weight multiplied by the DRG Base Price.
The posted APR-DRG Fee Schedule contains all of the above information.
Capital Related Costs
Capital cost is included in the DRG-based payment and will not be paid separately.
Cost Outlier Payments
It is recognized that there are occasional stays that are extraordinarily costly in relation to other stays within the same APR-DRG because of the severity of the illness or complicating conditions. These variations are recognized by the cost outlier payment which is an add-on payment for expenses that are not predictable by the diagnosis, procedures performed, and other statistical data captured by the APR-DRG grouper.
Cost outlier stays are stays that exceed the cost outlier threshold for the APR-DRG. To determine if a hospital stay exceeds the cost outlier threshold, the Montana Healthcare Programs program excludes all services that are not medically necessary. Montana Healthcare Programs then converts the charge information for medical necessary services into the estimated cost of the stay by applying the statewide average PPS inpatient cost-to-charge radio (CCR). The estimated cost for medically necessary services is then compared to the cost outlier threshold for the appropriate APR-DRG to determine if the stay qualifies for reimbursement as a cost outlier. Costs exceeding the threshold are multiplied by a marginal cost ratio to determine the cost outlier payment.
Transfer Payment Adjustments
The transfer payment adjustment applies when a patient is transferred to another acute care hospital. It does not apply when a patient is discharged to a post-acute setting such as a skilled nursing facility. The receiving hospital is not impacted by the transfer payment adjustment unless it transfers the patient to another hospital.
In the transfer payment adjustment, payment is calculated as if the beneficiary were not a transfer, then payment is adjusted. The APR-DRG Gross Payment is divided by the nationwide average length of stay for the assigned APR-DRG to arrive at a per diem amount. The per diem amount is then multiplied by the actual length of stay, except that payment is doubled for the first day to reflect costs related to the admitting process. If the transfer payment adjustment results in an amount greater than the amount without the adjustment, the transfer payment adjustment is disregarded. The cost outlier payment, if applicable, is then added to the APR-DRG base payment, with the transfer adjustment made as needed.
The transfer payment adjustment is not applicable to providers and services that are exempt from the Inpatient Prospective Payment Method.
Prorated Payment Adjustment
When a beneficiary has Montana Healthcare Programs coverage for fewer days than the length of stay, the payment is prorated. The APR-DRG Gross Payment plus cost outlier payments, if applicable, is divided by the nationwide average length of stay for the assigned APR-DRG to arrive at a per diem amount. The per diem amount is then multiplied by the number of days the beneficiary is eligible for Montana Healthcare Programs during the stay. If the prorated payment adjustment results in a payment amount greater than the amount without the adjustment, the prorated payment is disregarded.
The Prorated Payment Adjustment is not applicable to providers and services that are exempt from the Inpatient Prospective Payment Method. See the section titled Exempt Services and Costs.
The Cost-Based Payment Method for Exempt Hospitals and Services
The following providers are exempt from the Inpatient Prospective Payment Method. In the interest of clarity, this list includes acute care hospitals as well as facilities that provide similar inpatient services.
Exempt Services and Costs
The following services are exempt from the Inpatient Prospective Payment method even when provided by hospitals that are otherwise subject to prospective payment.
Reasonable Cost Reimbursement
Hospitals exempt from prospective payment will continue to use the Title XVIII retrospective reasonable cost principals for reimbursing Montana Healthcare Programs inpatient hospitals services. Allowable costs will be determined in accordance with generally accepted accounting principals as defined by the American Institute of Certified Public Accountants. Such definition of allowable costs is further defined in accordance with the Medicare Provider Reimbursement Manual, CMS Pub. 15-1, subject to the exceptions and limitations provided in the Department’s Administrative Rules. Pub. 15 is a manual published by the United States Department of Health and Human Services, CMS, which provides guidelines and policies to implement Medicare regulations which set forth principals for determining the reasonable cost of provider services furnished under the Health Insurance for Aged Act of 1965, as amended.
Hospitals subject to retrospective reasonable cost reimbursement shall receive interim payments weekly or biweekly during the facility’s fiscal year by submitting claims to the Department’s fiscal intermediary. The interim payment rate will be based on a percentage of customary (billed) charges to costs as determined by the facility’s most recently settled Montana Healthcare Programs cost report. If a provider fails to submit financial information to compute the rate, the provider will be reimbursed at 50 percent of its usual and customary billed charges. Hospital providers are required to submit the CMS 2552-96 to the Medicare Fiscal Intermediary (FI) and the Department within five months of their fiscal year end. The FI either audits or desk reviews the cost report, then sends the Department the “as adjusted” cost report. Montana Healthcare Programs settlements are made from the “as adjusted” cost report.
For each hospital that is a critical access hospital, reimbursement for reasonable costs of inpatient hospital services shall be limited to the lesser of 101 percent of allowable costs or the upper payment limit.
Services where Medicare is the primary payer (crossover claims) are not reimbursed using retrospective cost principles. Reimbursement for these services is the remaining coinsurance and deductible. The Department shall reimburse cost-based inpatient hospital service providers for certified registered nurse anesthetists costs on a reasonable cost basis.
Payment for hospital residents will be made as follows:
When a member has coverage from both Montana Healthcare Programs and another insurance company, the other insurance company is often referred to as third party liability (TPL). In these cases, the other insurance is the primary payer, and Montana Healthcare Programs makes a payment as the secondary payer. Montana Healthcare Programs will make a payment only when the TPL payment is less than the Montana Healthcare Programs allowed amount.
When a member has coverage from both Medicare and Montana Healthcare Programs, Medicare is the primary payer. Montana Healthcare Programs will pay the coinsurance and deductible, less any TPL or
incurment, on inpatient hospital claims for these dually eligible individuals.
Member Has Medicare and Montana Healthcare Programs Coverage. A provider submits an inpatient hospital claim for a member with Medicare and Montana Healthcare Programs. The Medicare coinsurance and deductible are $65.00 and $185.00. This total ($250.00) becomes the Montana Healthcare Programs allowed amount. Montana Healthcare Programs will pay this amount ($250.00) as long as no TPL or incurment amounts are applicable.
Member Has Medicare, Montana Healthcare Programs coverage, and TPL. A provider submits an inpatient hospital claim for a member with Medicare, Montana Healthcare Programs, and TPL. The Medicare coinsurance and deductible are $65.00 and $185.00. This total ($250.00) becomes the Montana Healthcare Programs allowed amount. The other insurance company paid $225.00. This amount is subtracted from the Montana Healthcare Programs allowed amount leaving $25.00. Montana Healthcare Programs pays $25.00 for this claim. If the TPL payment had been $250.00 or more, this claim would have paid at $0.00.
Disproportionate Share Hospital (DSH) payments, including routine and supplemental DSH payments, will be limited to the cap established by the Federal Centers for Medicare and Montana Healthcare Programs Services (CMS) for Montana.
Routine DSH shall receive an additional payment amount equal to the product of the hospital’s prospective base rate x the adjustment percent of 4% rural hospital and 10% urban hospitals. All Supplemental Disproportionate Share Hospitals (SDSH) shall receive an SDSH payment. DSH payments will only be given to eligible in-state hospitals.
