Montana coverage guide
Montana Insurers & Hospitals
Start with a company or hospital, then check the exact plan and network before choosing coverage or getting care in Montana.
A licensed Health Insurance Solutions agent can help you compare the plans we offer at no cost.
These listings come from dated public sources. A listing does not confirm network status, availability or that we offer a plan. Confirm the plan, doctor, location and date with both the insurer and provider.

Individual and family coverage
Health insurers in Montana
Individual, non-dental plans marked on-exchange in the CMS 2027 Exchange Plan Attributes file, updated October 20, 2026. The named insurers and plan counts are not a list of employer plans, Medicare plans or every insurer in the state.
Availability depends on your county, plan year and eligibility. These are not lists of employer or Medicare plans. A company can use different networks for different products.

Medicare Supplement in Montana
Medicare Supplement, also called Medigap, works with Original Medicare and is different from Medicare Advantage. Compare the plan letter, premium, enrollment rules and any Medicare SELECT network before choosing a policy.
Plan availability and prices can change. Plans C and F are generally limited to people first eligible for Medicare before 2020. We do not offer every policy shown.
Check current choices
Use Medicare.gov to search Medigap policies by ZIP code, and confirm the current company, plan, rate and eligibility before applying.

For small businesses
Small-group insurers in Montana
These companies appear in CMS’s 2027 annual small-group rate filings, updated October 30, 2026. Select a company to explore its new and renewing plan entries.
A filing does not establish approval or availability to your business. This list does not include every large-group, self-funded or other employer arrangement, and we do not offer every plan shown.
- Blue Cross and Blue Shield of Montana68 new or renewing plan entries in the filing
- Montana Health Cooperative12 new or renewing plan entries in the filing
- UnitedHealthcare Insurance Company22 new or renewing plan entries in the filing

Large employers and self-funded plans
Large-group and self-funded arrangements are not included in the small-group filing list above. A self-funded employer generally pays plan claims; an insurance company or another administrator may handle the network and administration. The name on a card alone does not identify how a plan is funded.
Ask the employer or plan administrator for the exact plan name, administrator and network, then verify the doctor, hospital and service with both the plan and provider.

Find a hospital
Montana hospitals
Search 67 Montana hospitals in CMS datasets by name, city, county or ZIP code.
These dated federal datasets are not a complete list of every hospital or a provider-network directory. County information is not provided for every record. A listing does not mean a hospital accepts your particular plan; confirm directly before you receive care.
