New Web Portal Password Reset Process

A self-serve reset function in the portal will be available beginning Monday 10/3.

Revalidation and Faxes:
Provider Relations has received concerns about an inability to get faxes submitted to the revalidation fax line, 406-457-9566.  If a provider is having trouble getting a fax through this line we suggest the following times to avoid the busy signal:
•    Mondays and Fridays are the lightest traffic
•    On any day, Early mornings and later afternoon are the best.  
•    The time to avoid is the 11 to 1 lunch hour

Montana Medicaid Health Improvement Program

The Health Improvement Program for Medicaid and HMK Plus members with chronic illnesses or risks of developing serious health conditions.

Provider referrals to HIP are encouraged.

Instructions and Provider Referral Form


Using Medicaid Card ID for Billing and Checking Eligibility

Providers should use the Medicaid member ID number, not the member’s Social Security number (SSN), for billing purposes and checking eligibility.

This ensures the expenditures are applied to the correct member and any query information is for the correct member. Errors can occur using the SSN for either billing or requesting eligibility information.

If you only have the member’s SSN, have questions, or need assistance, contact Provider Relations at 1.800.624.3958 or via e-mail at (PD012014)

Medicare/Medicaid Remittance Advice Reminder and Adjustments

If you do an adjustment, and use a Medicare Remittance Advice Template to print your Medicaid Remittance advice, be aware that not all templates will  accommodate the necessary Medicaid information to allow your adjustment to process. 

The issue is the length of the ICN that appears on the Medicare Remittance Advice Template. The Medicare ICN is formatted for 15 digits but the Medicaid ICN length is 17 digits. This will truncate the Medicaid ICN by 2 digits.

Check this field and make any necessary corrections. If this is not corrected, we will return your adjustment to you for correction. (PD032013)

Montana HELP Plan

HELP Plan Information Update

Providers can now use the updated Montana Access to Health (MATH) web portal eligibility inquiry tool to view eligibility for the Medicaid Expansion population. Members who present a Montana Access to Health card and are part of the Medicaid Expansion population will now display in the web portal as HELP Medicaid - FULL Coverage. 

The Integrated Voice Response (IVR) system (1-800-714-0060)  and FaxBack (1-800-714-0075) are also self-service eligibility inquiry tools providers can use to avoid long call wait times. For participants who present a BCBSMT card, providers should check eligibility through the BCBSMT Secure Provider Portal or call BCBSMT Provider Services at 1-877-296-8206.  These members will display on the MATH web portal as HELP - TPA - HELP TPA Plan.  Please see the Montana HELP Plan provider page for additional information.

Note:  HELP members who have more than one type of eligibility for Standard coverage benefits, for example HELP and Pregnant Medicaid, may display as Medicaid/HMK Plus-Full Coverage on the MATH web portal. Regardless of the Payer Name displayed, the individual has active full coverage.  A resolution to this issue is currently in progress. (PDR02082016)

EOB Reason and Remark Crosswalk

An updated version of the EOB Reason and Remark crosswalk, which matches the HIPAA standard R&R codes to the Medicaid EOB codes, is also posted under Other Resources on each provider page in PDF and Excel format.

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 is available at the link and 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. For more information on billing with NDCs on a UB-04, refer to the provider notice dated September 1, 2009.

Inappropriate Denials for Physician Administered Drugs for Rebate Agreement Not in Place

During the last payment cycle, Xerox identified claims for Physician Administered Drugs that were denied inappropriately as not being covered because a rebate agreement with the manufacturer was not in place.
