Plans offered in Natrona County
For 2027, CMS lists 3 Medicare Advantage plans in Natrona County, from one insurer; 2 of them include drug coverage. None is a special plan for people with both Medicare and Medicaid. Wyoming also has 9 stand-alone drug plans (Part D), available in every county. Source: the CMS CY2027 Landscape file, data updated November 1, 2026, read November 9, 2026.[5]
How Medigap works when you travel for care
Outside the Casper hospitals, doctor networks thin out fast, and plenty of people here see specialists in Denver, Billings or Salt Lake City. A Medigap policy works with any provider in the country that takes Medicare.[4]
Timing matters. You get a six-month Medigap open enrollment period starting the month you are 65 or older and enrolled in Part B. During it, an insurer must sell you any Medigap policy it offers, at the same price as someone in good health.[1]
Medicare Advantage is the other route: a private plan that replaces Original Medicare, usually with a network, often with drug cover built in. If you choose one, check that your Casper doctors and your pharmacy are in it.[4]
Dates to put on the fridge
- October 15 to December 7: change Medicare Advantage or Part D plans for the next year.[2]
- January 1 to March 31: one switch between Advantage plans, or back to Original Medicare.[2]
- Your 65th birthday: seven months to sign up, three before, the month itself, three after.[2]
- A move, or a move into or out of a nursing home, can open a Special Enrollment Period.[3]
