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 Colorado, 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 Grand County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: Colorado State Health Insurance Assistance Program (SHIP) gives free, unbiased counseling at 303-894-7552. Ask which plans serve Grand County specifically.
- Marketplace plans: shop through Connect for Health Colorado; enter your Grand County ZIP code to see what is offered.
- Medicaid: apply through Health First Colorado (Department of Health Care Policy and Financing).
Colorado note: Colorado's Medicaid program goes by its own brand name, Health First Colorado, rather than being called Medicaid directly on member-facing materials -- worth knowing since Colorado-specific paperwork and enrollment sites generally lead with that name instead.
