  • Buying your own plan? Shop through Connect for Health Colorado.
  • Medicaid questions? Health First Colorado (Department of Health Care Policy and Financing) handles applications.

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.

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).
