Medicare is a national health insurance program in the United States, begun in 1966 under the Social Security Administration and now administered by the Centers for Medicare and Medicaid Services (CMS). It primarily provides health insurance for Americans age 65 and older, persons with disability status as determined by the Social Security Administrations, as well as people with end stage renal disease and amyotrophic lateral sclerosis.

As is the case nationwide, enrollment in private Medicare plans grew in Minnesota in 2018. As of December 2018, there were 581,822 Minnesota Medicare beneficiaries with private Medicare coverage, which amounts to nearly 58 percent of the state’s Medicare population. Nationwide, most people with private Medicare plans are enrolled in Medicare Advantage plans, but Medicare Cost plans are another type of private Medicare coverage, and as of 2018, Minnesota residents accounted for two-thirds of the national total enrollment in Medicare Cost plans.

As a result, an estimated 320,000 Medicare Cost enrollees in Minnesota needed new coverage for 2019. There are 21 counties where Medicare Cost plans continue to be available, but Medicare Cost enrollees in the rest of the state were not able to keep their Cost plans. Instead, they had the option to enroll in a Medicare Advantage plan (some were automatically enrolled in a comparable Medicare Advantage plan, although they had an option to pick something else instead), or select a Medigap plan to supplement their Original Medicare. Enrollees whose Medicare Cost plans ended have guaranteed issue rights to a Medigap plan, so they can purchase one even if they had pre-existing medical conditions. But that guaranteed-issue right only lasts for 63 days, which means Monday, March 4, 2019 is the last day these individuals can purchase a Medigap plan without having to go through medical underwriting.


As of 2018, there were 370,000 Medicare Cost plan enrollees in Minnesota, but most of them had to switch to new plans (either Medicare Advantage or Original Medicare) for 2019. This is described in more detail below, but Minnesota’s enrollment in private Medicare plans could end up fluctuating significantly for 2019, depending on how many of those enrollees opted to have coverage under Original Medicare versus Medicare Advantage.

Medicare Part D is optional prescription drug coverage. If you have Original Medicare, you can get this coverage through a Medicare Prescription Drug Plan, offered through private Medicare-approved insurance companies. These plans offer stand-alone prescription drug coverage that work alongside Original Medicare, Part A and Part B. A Medicare Advantage Prescription Drug plan also provides the Medicare Part D benefit, covering all Medicare benefits under a single plan.


Original Medicare does not limit out-of-pocket costs, so most enrollees maintain some form of supplemental coverage. Nationwide, more than half of Original Medicare beneficiaries get their supplemental coverage through an employer-sponsored plan or Medicaid. But for those who don’t, Medigap plans (also known as Medicare supplement plans, or MedSupp) will pay some or all of the out-of-pocket costs they would otherwise have to pay if they had only Original Medicare.
Minnesota law prevents Medigap insurers from imposing pre-existing condition waiting periods if the enrollee signs up 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 plan.
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 as of 2019.

The Minnesota Board on Aging (MBA) may be helpful for seniors seeking a wide range of information. The office provides education in a broad range of areas, including health-care coverage and Medicare plans. The office was first established in 1956. Since that time, seniors have been able to turn to the Minnesota Board of Aging for a variety of programs, including:
Since 1997, Minnesota has provided Medicare coverage for approximately 35,000 Medicare-Medicaid eligible individuals over age 65 through the Minnesota Senior Health Options (MSHO) program. Today, the Minnesota demonstration recognizes this program stability and is focused on administrative flexibility rather than developing a new capitated system. The current demonstration will be evaluated for its ability to further promote integration. However, the longevity of the MSHO program provides for unique data analysis opportunities. MSHO claims data are a rich resource for researchers to analyze the impact of integrated care on health care outcomes for Medicare-Medicaid eligible.  To that end, the Office of the Assistant Secretary for Planning and Evaluation (ASPE) published Minnesota Managed Care Longitudinal Data Analysis which highlights the importance of providing integrated options for Medicare-Medicaid eligible individuals.
