PALMELLEWhat is happening
UnitedHealthcare sold Medicare Advantage plans in Natrona County in 2026. Medicare's plan list for 2027 has none from UnitedHealthcare in Natrona County. The same is true in Laramie and Sheridan counties.[5]
If you are in one of those plans, it ends on December 31, 2026. UnitedHealthcare's stand-alone drug plans are still on the 2027 list for Wyoming; this is about its Medicare Advantage plans.[5]
Your dates
- Until December 7: fall open enrollment. Anyone on Medicare can join a plan for January 1.[2]
- December 8 to the last day of February: a special window for people whose plan was not renewed. You can still join another plan in this window.[3]
If you do nothing, Medicare moves you to Original Medicare when your plan ends.[3]
What is left in Natrona County for 2027
Three Medicare Advantage plans, all from one insurer, stay on the county's 2027 list.[5] The home page of this guide has the full count.
Your right to buy a Medigap policy
When a plan ends your coverage, federal law can give you a right to buy a Medigap policy without health questions. Apply no more than 63 days after your coverage ends, and keep the letter from your plan as proof.[11]
