A plan can be listed because it was renumbered or replaced, not only because a company is leaving the county. When the same company keeps other plans there, members are usually moved to a replacement plan. Your plan should send you a notice, and Medicare’s Annual Enrollment Period (October 15 to December 7) is when you can compare and switch. “People enrolled” is the number enrolled in that plan today (CMS hides counts of 10 or fewer).

Why your county matters for coverage
In Montana, the health plans you can choose depend on where you live. Medicare Advantage and Part D plans are offered by service area, usually county by county, and marketplace premiums and carriers are set by area as well. Living in Madison County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: Montana SHIP (State Health Insurance Assistance Program) gives free, unbiased counseling at 1-800-551-3191. Ask which plans serve Madison County specifically.
- Marketplace plans: shop through HealthCare.gov (federal Marketplace); enter your Madison County ZIP code to see what is offered.
- Medicaid: apply through Montana Department of Public Health and Human Services (DPHHS).
Montana note: Montana's SHIP counselors work through the state's network of Area Agencies on Aging rather than a single centralized call center, so a caller can often be connected with someone local to their part of the state rather than a statewide hotline.
