Medicare in Wyoming

Medicare enrollment in Wyoming

As of February 2026, there were 131,963 Wyoming residents enrolled in Medicare coverage.¹

For most individuals, eligibility for Medicare happens at age 65. But Medicare eligibility is also triggered by receiving certain disability benefits for at least two years, or by a diagnosis of end-stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS). Nationwide, about 9% of Medicare beneficiaries are under the age of 65.² In Wyoming, it’s 8%; the other 92% of Wyoming Medicare beneficiaries are eligible because they’re 65 or older.¹

Medicare Advantage plan availability and enrollment in Wyoming

Most Wyoming Medicare beneficiaries opt for Original Medicare – only 20,346 people in Wyoming had Medicare Advantage coverage as of February 2026.¹ That’s due in large part to the fact that until the last few years, much of Wyoming simply didn’t have many Medicare Advantage plans available for purchase. Prior to 2019, there were no Medicare Advantage plans in 15 of the state’s 23 counties³

But starting in 2019, one carrier began offering Medicare Savings Account (MSA) plans – a type of Medicare Advantage plan – statewide in Wyoming.⁴ And other Medicare insurers have joined the state’s market since then.

The MSAs are no longer available after the end of 2023,⁵ but all counties in Wyoming have at least two Medicare Advantage plans available as of 2026, and most have three or more⁶ (they may all be offered by the same insurance company, depending on the county). ⁷

Medicare supplement (Medigap) plan availability in Wyoming

According to AHIP, 58,604 Wyoming residents had Medigap coverage as of 2023,⁸ to supplement their Original Medicare coverage.

As of 2026, at least 19 insurers sold Medigap plans in Wyoming, although the state insurance department noted this might not be a comprehensive list.⁹

Learn how Medigap plans are regulated and standardized.

Federal rules do not provide for an annual open enrollment period for Medigap. If a person applies for Medigap coverage after their initial enrollment period ends, the insurer can use medical underwriting to determine their eligibility and pricing (assuming they don’t qualify for a special enrollment period with guaranteed-issue rights).

Wyoming’s Medigap birthday rule

But states can provide additional enrollment opportunities. In mid-2025, Wyoming joined the list of states that offer “birthday rule” Medigap enrollment windows. Under Wyoming’s rule, Medigap enrollees have a 63-day window, starting on their birthday, when they can switch to any available Medigap plan that offers the same or lesser benefits,¹⁰ without underwriting.¹¹

Medigap access for Wyoming residents under age 65

There are no federal rules to ensure access to Medigap plans for people under age 65. According to Medicare’s plan finder tool, there are no insurers offering Medigap plans to beneficiaries under age 65 in 2026.¹²

However, the Wyoming Health Insurance Pool provides guaranteed-issue coverage for applicants who are unable to obtain Medigap coverage due to medical underwriting.

Wyoming is one of several states where state-run high-risk pools are still operational, with supplemental insurance coverage available to Medicare beneficiaries who are unable to obtain Medigap insurance policies.¹³ Wyoming enacted legislation in 2019 that extends the operation of the Wyoming Health Insurance Pool through 2030.¹⁴

Medicare Part D plan availability and enrollment in Wyoming

As of February 2026, more than 95,000 Wyoming Medicare beneficiaries were enrolled in Part D prescription coverage. Most of them – nearly 80,000 – had stand-alone Medicare Part D prescription drug plans, while 15,783 were enrolled in Medicare Advantage plans that had integrated Part D prescription coverage.¹

For 2026 coverage, there are 11 stand-alone Medicare Part D prescription drug plans (PDPs) available in Wyoming, with premiums starting at $4.70 per month.¹⁵
