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 Missouri, 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 Johnson County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: CLAIM (Community Leaders Assisting the Insured of Missouri) gives free, unbiased counseling at 800-390-3330. Ask which plans serve Johnson County specifically.
- Marketplace plans: shop through HealthCare.gov (federal Marketplace); enter your Johnson County ZIP code to see what is offered.
- Medicaid: apply through MO HealthNet (Missouri Department of Social Services).
Missouri note: Missouri's Medicare counseling program, CLAIM, is run as an independent nonprofit rather than directly out of a state agency -- a different structure than most states' SHIP programs, though it's still the officially designated, federally-recognized SHIP for Missouri.
