Medicare in Wyoming

Most Wyoming Medicare beneficiaries opt for Original Medicare – only 22,825 people had Medicare Advantage coverage as of July 2024, which amounts to about 18% of Wyoming’s Medicare population enrolled in Medicare Advantage plans¹ (although that’s up from just 6% in 2021).¹⁰ Nationwide, more than half of all Medicare beneficiaries were enrolled in Medicare Advantage plans as of mid-2024,⁹ but Original Medicare enrollment in Wyoming is much more popular.

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 counties¹¹

But starting in 2019, one carrier began offering Medicare Savings Account (MSA) plans — a type of Medicare Advantage plan — statewide in Wyoming.¹² And other Medicare insurers have joined the state’s market since then.

The MSAs are no longer available after the end of 2023,¹³ but all counties in Wyoming have at least three Medicare Advantage plans available as of 2024 (they may all be offered by the same insurance company, depending on the county).^{14 5}

And all counties in Wyoming continue to have Medicare Advantage plans available for 2025.⁴

Medicare Advantage plans provide all of the benefits of Original Medicare (Part A, hospital coverage, and Part B, outpatient/medical coverage), although out-of-pocket costs and provider network access can differ considerably. Medicare Advantage plans also tend to include additional benefits, including Medicare Part D prescription drug coverage for drugs, nurse hotlines, fitness, and covered dental and vision services. But Medicare Advantage plans also tend to have much more limited provider networks than the nationwide access granted by Original Medicare, and they also tend to use things like prior authorization and step therapy to contain costs.

Medicare Advantage plan enrollment is available when a person is first eligible for Medicare, and there’s the Medicare Annual Open Enrollment Period (October 15 to December 7) when beneficiaries can switch to or from Medicare Advantage, or pick a different Medicare Advantage plan. There is also a window at the start of the year (January 1 to March 31) when people who are already enrolled in Medicare Advantage plans can switch to a different Medicare Advantage plan or switch to Original Medicare instead.

Original Medicare does not have a cap on out-of-pocket costs (the deductible, copay and coinsurance the people pay when they need medical care), so most beneficiaries rely on some sort of supplemental insurance coverage.¹⁵

Many have Medicare supplement insurance coverage from a current or former employer, or from Medicaid. But for those who don’t, Medigap plans provide supplemental insurance coverage that pays some or all of the out-of-pocket expenses Original Medicare beneficiaries would otherwise have to pay on their own.

Medigap plans are standardized at the federal level, with ten different plan options available, but not all insurers offer all plan options.

For people who are age 65 or older, 27 insurance companies offered Medigap plans in Wyoming as of 2024.⁵

The Wyoming Department of Insurance publishes an annual buyer’s guide for Medigap coverage (here’s the 2024 guide) with helpful state-specific information related to Medicare plans. The guide notes that people under age 65 who have Medicare eligibility in Wyoming due to a disability are not guaranteed access to a Medigap plan, and that insurers can use medical underwriting to determine eligibility for people under 65 — all of whom have at least one significant pre-existing condition (because their Medicare eligibility stems from a long-term disability).

There are no federal rules to ensure access to Medigap plans for people under age 65. Many states have taken action to address this, but Wyoming has not.

According to Medicare’s plan finder tool, only one insurer  (United American) offers Medigap coverage to Wyoming applicants under 65 for 2025. They offer only Plan B and high-deductible Plan F for these enrollees, and at much higher premiums than the standard rates (under federal rules, any version of Plan F can only be purchased by someone who became eligible for Medicare prior to 2020).⁶

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.¹⁶ Wyoming enacted legislation in 2019 that extends the operation of the Wyoming Health Insurance Pool through 2030.¹⁷

Unlike other Medicare plan coverage options (ie, Medicare Advantage and Medicare Part D prescription drug plans), there is no annual open enrollment period for Medigap insurance policies. Coverage is guaranteed-issue during the first six months that a person is at least 65 and also enrolled in Medicare Part A and Medicare Part B. After that, in most circumstances, insurers can use medical underwriting if a person applies for a Medigap policy.

(The exception to this is a case where a person has a guaranteed-issue right to Medigap due to various circumstances, such as being enrolled in a Medicare Advantage plan that will no longer be offered for the coming year.)

Original Medicare does not cover outpatient prescription drugs. But Medicare beneficiaries can get coverage for prescription drugs via a Medicare Advantage plan, an employer-sponsored plan (offered by a current or former employer), or a stand-alone Medicare Part D prescription drug plan. In areas where Medicare Advantage plan enrollment is lower, Medicare Part D prescription drug plan enrollment for stand-alone plans tends to be higher.¹

As of July 2024, almost 92,000 Wyoming Medicare beneficiaries were enrolled in Part D prescription coverage. Most of them — more than 72,000 — had stand-alone Medicare Part D prescription drug plans, while about 19,000 were enrolled in Medicare Advantage plans that had integrated Part D prescription coverage.¹

For 2025 coverage, there are 16 stand-alone Medicare Part D prescription drug plans (PDPs) available in Wyoming, with premiums starting at $0 per month.⁴

Medicare Part D prescription drug enrollment is available when a person is first eligible for Medicare, and the same fall Annual Enrollment Period that applies to Medicare plans is also used for Medicare Part D prescription drug plans: Beneficiaries can enroll in a Medicare Part D prescription drug plan or switch to a different plan between October 15 and December 7, with coverage effective the first of the following year.

It’s recommended that beneficiaries use Medicare’s plan finder tool each year to actively compare the available options and see how each plan will cover their prescription drugs in the coming year; plans change from one year to the next, and so do beneficiaries’ medication needs. A more costly plan in terms of monthly premiums might work out to be the best option, due to lower out-of-pocket costs when the enrollee fills prescriptions throughout the year.

Many Medicare beneficiaries receive financial assistance through Medicaid with the cost of Medicare premiums and services Medicare doesn’t cover – such as long-term care.

Our guide to financial assistance for Medicare enrollees in Wyoming includes overviews of these benefits, including Medicare Savings Programs, long-term care coverage, and eligibility guidelines for assistance.
