Blue Cross Medicare AdvantageSM

The Blue Cross Medicare Advantage Plan offers all of the coverage of Original Medicare — plus benefits not covered by Medicare or most Medicare Supplement insurance plans, including built-in prescription drug coverage.

  • The 2018 Blue Cross Medicare Advantage (PPO)SM plan offers health coverage to members who reside in Missoula, Cascade, Lake, Lewis & Clark, Flathead, Lincoln, Gallatin, Ravalli and Yellowstone counties.

Our strong brand recognition and our historical relationship with Medicare makes Blue Cross and Blue Shield of Montana (BCBSMT) an excellent choice for Medicare eligible individuals seeking new health coverage opportunities. Blue Cross Medicare Advantage maintains and monitors a network of participating providers including physicians, hospitals, skilled nursing facilities, ancillary providers, and other health care providers through which members obtain covered services.


Participating physicians, professional providers, and facility providers must submit claims to Blue Cross Medicare Advantage within 365 days of the date of service, using the standard CMS-1500 or UB-04 claim form, or electronically. Services billed beyond 365 days from the date of service are not eligible for reimbursement.
