Contacting BCBSMT Customer Service

November 9, 2022

Blue Cross and Blue Shield of Montana (BCBSMT) has implemented an Interactive Voice Response (IVR) automated phone system for providers to verify the patient’s eligibility and benefit details, submit and/or check status for prior authorization requests, and request claim adjustments.

The IVR provides you quick access to needed information without waiting to speak with a Customer Advocate. You also have the option to use your touch tone keypad to enter alpha-numeric characters and receive a faxed confirmation of the IVR quote.

Obtaining Eligibility and Benefits and Requesting Claim Adjustments

  • Eligibility and benefit quotes include membership verification, coverage status and other important information, such as applicable copayment, coinsurance, deductible amounts, and code-specific prior authorization requirements.
  • To request a commercial claim adjustment, the document control number (claim number) is required when calling the IVR to connect with a Customer Advocate for assistance. General claim status is not available in the IVR, but can be quickly obtained online using the Availity® Claim Status Tool, or the web vendor of your choice.

The IVR phone system is accessible by calling 800-447-7828 Monday through Friday, 5 a.m. to 10:30 p.m., MT, and Saturday, 5 a.m. to 5 p.m., MT.

Requesting Prior Authorization

When BCBSMT requires the service to be preauthorized, you can initiate the request and/or check the status by calling the prior authorization IVR phone system at 855-313-8914 Monday through Friday, 5 a.m. to 10:30 p.m., MT, and Saturday, 5 a.m. to 5 p.m., MT.
