Medicare in Minnesota

Private Medicare Advantage plans are an alternative to Original Medicare (Medicare Part A, hospital coverage, and Medicare Part B, outpatient/medical coverage). Medicare Advantage plans include all of the covered benefits of Original Medicare⁷ (although there can be significant differences in the out-of-pocket costs), and most Medicare Advantage plans also include Medicare Part D prescription drug coverage and may offer extra benefits like dental and vision coverage, a nurse hotline service, and fitness.

But Medicare Advantage plans tend to have limited provider networks, and out-of-pocket costs may be higher than they would be with Original Medicare plus a Medigap plan and Medicare Part D prescription drug plan. There are pros and cons to either option, and the right solution is different for each person.

Plan availability varies by county, but Minnesota’s Medicare Advantage market is strong: Residents throughout the state can select from among at least 8 Medicare Advantage plans for 2025, and some counties have more than 40 different plan options for sale.²

The Annual Enrollment Period (October 15 – December 7) allows Medicare beneficiaries the opportunity to change their Medicare Advantage coverage if they choose to do so.

About 60% of all Minnesota Medicare enrollees were enrolled in Medicare Advantage plans as of September 2024,¹ as opposed to a national average of about 50%.⁶

(Note that these numbers refer to people who are enrolled in a private plan to replace Original Medicare, as opposed to a plan to supplement it — so stand-alone Medicare Part D prescription drug plans and Medigap policies are not counted when we talk about more than half of Minnesota’s Medicare beneficiaries being enrolled in private plans.)

Private plan enrollment already accounted for well over half of Minnesota’s Medicare beneficiaries several years ago, but it dropped in 2019 and has climbed again since then in line with Medicare Advantage growth nationwide. But the percentage of Minnesota Medicare beneficiaries with private coverage has been climbing again since then, with nearly 58% of the state’s beneficiaries enrolled in private plans by 2023.

Minnesota was the first to participate in a demonstration program to pilot Medicare Cost plans in the 1970s, and the plans remained popular over the decades. They didn’t catch on in many other states, however, and Medicare + Choice came on the national scene in the 1990s, replaced by Medicare Advantage in 2003.

The legislation that introduced Medicare Advantage also created a competition clause that banned Medicare Cost plans from operating in areas where they faced substantial competition from Medicare Advantage plans, but the implementation of the competition clause was delayed for many years. In 2015, legislation (MACRA) called for the competition clause to be implemented in 2019.

As a result, Medicare Cost Plans were discontinued in 66 Minnesota counties.⁸ These Medicare Cost Plans include Medicare Part A and Part B coverage, but with the flexibility to see non-network providers. A Medicare Cost Plan may also include the option of obtaining separate Medicare Part D prescription drug coverage.⁸ In 2011, 24% of Minnesotans were enrolled in Medicare Cost Plans. As of December 2020, about 6% of state residents had Medicare Cost plans.⁹

One of the reasons Medicare Cost has been so popular in Minnesota is that the state has a large population of “snowbirds” — retirees who live in Minnesota during the summer, but head south to warmer climes in the winter. With Medicare Cost plans, the enrollee still has Original Medicare — including the large nationwide network of providers who work with Medicare — in addition to the Medicare Cost coverage. Medicare Advantage plans, in contrast, tend to have localized networks that might not be suitable for a senior who lives in two different states during the year. A Medigap plan plus Original Medicare will allow a person in that situation to have access to health providers in both locations, although Medigap tends to be more expensive than Medicare Advantage. There are pros and cons to both options, and no one-size-fits-all solution.

As of 2023, there were still Medicare Cost plans available in 21 counties in Minnesota. Medicare Cost plans in the state are offered by Blue Cross Blue Shield of Minnesota and Medica (as of 2022, there were also Cost plans offered by Health Partners, but their policies are no longer available in Minnesota as of 2023)

Original Medicare does not limit out-of-pocket costs, so most enrollees maintain some form of supplemental coverage. Nationwide, about 47% of Original Medicare beneficiaries get their supplemental coverage through an employer-sponsored plan or Medicaid in 2020.¹⁰ But for those who don’t, optional Medigap policies (also known as Medicare supplement insurance plans, or MedSupp) will pay some or all of the out-of-pocket costs (deductibles and coinsurance) they would otherwise have to pay if they had only Original Medicare.

Thirteen insurers offer Medigap policies in Minnesota as of 2022.¹¹ According to America’s Health Insurance Plans (AHIP) analysis, 215,767 people had Medigap coverage in Minnesota as of 2022.¹² But as noted above, hundreds of thousands of people had to leave their Medicare Cost plans at the end of 2018 and transition either to Medicare Advantage or Original Medicare — with a Medigap supplement if they wanted one.

In all but three states, Medigap policies are standardized under federal rules.¹³ But Minnesota is one of three states that have federal waivers that allow the state to do its own Medigap standardization. So instead of the ten Medigap plans (A through N) that are marketed in most states, Minnesota Medigap plans include Basic, Basic with riders, Extended Basic, and Medigap plans F, K, L, M, and N.

Minnesota law prevents Medigap insurers from imposing pre-existing condition waiting periods if the beneficiary enrolls during their initial six-month open enrollment window. For those who apply after that, Medigap insurers are not allowed to impose pre-existing condition waiting periods if the enrollee wasn’t diagnosed or treated for the condition in the 90 days prior to enrolling in the Medigap policies.¹⁴

People who aren’t yet 65 can file for Medicare benefits if they’re disabled and have been receiving disability benefits for at least two years, and about 10% of Minnesota Medicare beneficiaries are under age 65. Federal rules do not guarantee access to Medigap plans for people who are under 65, but the majority of the states — including Minnesota — have implemented rules to ensure that disabled Medicare beneficiaries have at least some access to Medigap plans. Minnesota law grants a six-month open enrollment period to anyone who enrolls in Medicare Part B, regardless of age (federal rules only grant this window to people who enroll in Part B and are also at least 65 years old).

After that six-month window ends, Medigap insurers can use medical underwriting to determine an applicant’s eligibility for coverage. Bipartisan legislation was introduced in Minnesota in 2020 (SF3897 and HF4030) that would have required Medigap policies to be guaranteed-issue year-round, but it did not advance out of committee.¹⁵¹⁶ New York and Connecticut are currently the only two states that require insurers to offer ongoing guaranteed-issue access to Medigap policies.

Minnesota also prohibits Medigap insurers from basing premiums on an enrollee’s age. Premiums for Medigap plans in Minnesota only vary based on tobacco use and where the enrollee lives. These rating rules also apply to people who are eligible for Medicare before the age of 65, which is somewhat unusual; most of the states that have guaranteed access to Medigap for under-65 enrollees do allow the insurers to charge those enrollees higher premiums.

Original Medicare does not provide coverage for outpatient prescription drugs. About 47% of Original Medicare beneficiaries nationwide have supplemental coverage via an employer-sponsored plan (from a current or former employer or spouse’s employer) or Medicaid, and these plans often include prescription coverage.¹⁰ Some Medigap plans that were sold prior to 2006 included coverage for prescription drugs, but sales of those plans ceased as of 2006, when Medicare Part D became available. Medicare prescription drug Part D was created under the Medicare Modernization Act of 2003, which was signed into law by President George W. Bush.¹⁷

For people who have enrolled in Medicare since 2006 and who don’t have prescription drug coverage through Medicaid or an employer-sponsored plan, Medicare Part D prescription drug plan enrollment is essential in order to have coverage for prescriptions. Medicare Part D prescription drug is optional, and can be purchased as a stand-alone plan, or integrated with a Medicare Advantage plan.

There are 16 stand-alone Medicare Part D prescription drug plans for sale in Minnesota for 2025, with premiums starting at $0 per month.³ The same open enrollment period that applies to Medicare Advantage plans (October 15 to December 7) also applies to Part D plans. During this period, Medicare beneficiaries can change their Medicare Part D prescription drug coverage, with the new plan taking effect January 1.

In Minnesota, as of September 2024, there were 347,302 people with stand-alone Medicare Part D prescription drug coverage. Another 612,520 Medicare beneficiaries in Minnesota had Medicare Part D prescription drug coverage as part of their Medicare Advantage plans.¹

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.
