Drug and Pharmacy News

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 is available at the on appropriate provider pages. To determine if a manufacturer has signed a rebate agreement, check the first 5 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 please 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). For more information on billing with NDCs on a CMS-1500, refer to the provider notice dated April 10, 2008.
