Please note, as of January 1, 2026, Western Montana Clinic providers and facilities (including Lab), are no longer contracted with Humana Medicare Advantage products. WMC does still accept Humana Medicare Supplemental plans.

Western Montana Clinic is a preferred provider with and contracts with many other insurance companies and still accepts original Medicare and BCBS Medicare Advantage. However, occasionally our partnership with an insurance company may need to change for various reasons, as was the case with Humana Medicare Advantage. We suggest that you always contact your insurance company prior to a visit, test or procedure to verify eligibility and coverage or contact our Central Billing Offices at 406-721-5600.
