Common Billing Errors

Paper claims are often returned to the provider before they can be processed, and many other claims, both paper and electronic, are denied. To avoid unnecessary returns and denials, double check each claim to confirm the following items are included and accurate.

**Common Billing Errors**
Reasons for Return or Denial	How to Prevent Returned or Denied Claims
Provider’s NPI and/or Taxonomy is missing or invalid	The provider NPI is a 10-digit number assigned to the provider by the national plan and provider enumerator system. Verify the correct NPI and Taxonomy are on the claim.
Authorized signature missing	Each claim must have an authorized signature belonging to the provider, billing clerk, or office personnel. The signature may be typed, stamped, hand-written, or computer-generated.
Signature date missing	Each claim must have a signature date.
Incorrect claim form used	The claim must be the correct form for the provider type.
Information on claim form not legible	Information on the claim form must be legible. Use dark ink and center the information in the form locator. Information must not be obscured by lines.
Member ID number not on file, or member was not eligible on date of service	Before providing services to the member, verify member eligibility by using one of the methods described in the Member Eligibility and Responsibilities chapter of this manual. Montana Healthcare Programs eligibility may change monthly.
Passport provider number is missing or invalid	A Passport provider number must be on the claim form when a referral is required. Passport approval is different from prior authorization. See the Passport to Health provider manual.
Prior authorization number is missing	Prior authorization is required for certain services, and the prior authorization number must be on the claim form. Prior authorization is different from Passport. See the Prior Authorization chapter in this manual.
Prior authorization does not match current information	Claims must be billed, and services performed during the prior authorization span. The claim will be denied if it is not billed according to the spans on the authorization.
Duplicate claim	Check all remittance advices for previously submitted claims before resubmitting. When making changes to previously paid claims, submit an adjustment form rather than a new claim form. (See Remittance Advices and Adjustments in this manual.)
TPL on file and no credit amount on claim	If the member has any other insurance (or Medicare), bill the other carrier before Montana Healthcare Programs. If the member’s TPL coverage has changed, providers must notify the TPL unit before submitting a claim.
Claim past 365-day filing limit	The Claims Processing unit must receive all clean claims and adjustments within the timely filing limits described in this chapter. To ensure timely processing, claims and adjustments must be mailed to Claims Processing.
Missing Medicare EOMB	All denied Medicare crossover claims must have an Explanation of Medicare Benefits (EOMB) with denial reason codes attached and be billed to Montana Healthcare Programs on paper.
Provider is not eligible during dates of services, enrollment has lapsed due to licensing requirements, or provider number terminated	Out-of-state providers must update licensure for Montana Healthcare Programs enrollment early to avoid denials. If enrollment has lapsed due to expired licensure, claims submitted with a date of service after the expiration date will be denied until the provider updates his or her enrollment. New providers cannot bill for services provided before Montana Healthcare Programs enrollment begins. If a provider is terminated from the Montana Healthcare Programs program, claims submitted with a date of service after the termination date will be denied. After updating his/her license, the claims that have been denied must be resubmitted by the provider.
Procedure is not allowed for provider type	Provider is not allowed to perform the service. Verify the procedure code is correct using current HCPCS and CPT coding books. Check the appropriate Montana Healthcare Programs fee schedule to verify the procedure code is valid for your provider type.

Eligible Drug Manufacturers

Montana Medicaid reimburses only for drugs that are manufactured by companies that have a signed rebate agreement with CMS. An updated list of these manufacturers has been posted on the Site Index under Rebateable Manufacturers.

To determine if a manufacturer has signed a rebate agreement, check the first five digits of the National Drug Code (NDC) against the list. If there is no match, the drug is not reimbursable.

The list will be updated quarterly, so check regularly to assure coverage.

In addition, the valid NDC must be recorded on the claim (no spaces, no punctuation) as an 11-digit series of numbers. Claims will be denied for drugs billed without a valid 11-digit NDC. Providers also must be careful when entering the NDC quantity (the administered amount).
