Michigan’s health insurance marketplace

State legislative efforts to preserve or strengthen provisions of the Affordable Care Act

How hard is Michigan fighting to preserve the Affordable Care Act’s provisions? Compare to other state-level efforts.

Michigan has a state-federal partnership exchange, and residents use HealthCare.gov to enroll in individual and family health plans. These plans are used by people who have retired prior to age 65, people who are self-employed, and people who work for a small employer that doesn’t provide health insurance benefits.

Nine insurers offer coverage for 2020 in the Michigan exchange, and all nine will continue to offer policies for 2021. In addition, there are two insurers that offer individual market coverage in Michigan only outside the exchange.

After increasing individual market premiums by an average of just 1.7 percent for 2019, Michigan’s insurers reduced their average premiums by about 2.5 percent for 2020. For 2021, they have proposed average rate changes that range from a decrease of 2 percent to an increase of 6 percent, with an overall average proposed rate increase of about 1.3 percent.

Premium subsidies are available for people with income up to 400 percent of the poverty level. For 2021 coverage, that amounts to $51,040 for a single individual and $104,800 for a family of four. As of 2020, 86 percent of Michigan exchange enrollees were receiving premium subsidies, which reduce monthly premium costs to affordable levels. Premium subsidies are not available outside the exchange, so purchasing a health insurance policy directly from an insurance company (instead of through the exchange) is generally only a good option for people who know they won’t be eligible for a subsidy.


In 2020, enrollment in Michigan’s health insurance marketplace reached 262,919, down from about 274,000 the year before. As was the case in Michigan, enrollment peaked in 2016 in the majority of the states that use HealthCare.gov, and has declined since then for a variety of reasons: The Trump administration’s decision to reduce funding for exchange marketing and enrollment assistance, the elimination of the individual mandate penalty, the expansion of short-term plans, and the premium increases in 2017 and 2018 that made coverage unaffordable for some enrollees who didn’t qualify for premium subsidies (most enrollees need subsidies in order to make coverage affordable, but subsidies are not available to households that earn more than 400 percent of the poverty level).

Michigan open enrollment period and dates

Open enrollment for 2021 health plans is November 1, 2020 through December 15, 2020. Outside of that window, Michigan residents can only enroll in individual market major medical policies (on-exchange or off-exchange) if they experience a qualifying event.

The open enrollment period is an opportunity to renew or change an existing plan for the coming year, or to newly enroll in individual market coverage. It’s also a good time to update financial information on file with the exchange, to ensure that premium subsidies are accurate for the coming year.

The November 1 – December 15 open enrollment period only applies to individual major medical health plans. It does not apply to health plans provided by an employer or to Medicaid or Medicare. Employers set their own open enrollment schedules, Medicaid enrollment is available year-round, and Medicare open enrollment (for Part D and Medicare Advantage plans) follows a different schedule.

Michigan and the Affordable Care Act

Michigan was considered a red state following the 2014 elections, and support for the Affordable Care Act has been mixed. But the tide has been turning more recently. Following the 2018 election, Michigan’s state legislature is still GOP-dominated, but the margins are much smaller than they were. And Democrats were elected to serve as governor, secretary of state, and attorney general.

Sens. Carl Levin and Debbie Ann Stabenow, both Democrats, voted in favor of the Affordable Care Act in 2010. Levin retired in January 2015 and was replaced by U.S. Rep. Gary Peters, a Democrat. Peters voted for the ACA in the House in 2010.

Michigan’s delegation to the U.S. House of Representatives split along party lines in the 2010 ACA vote. Eight Democrats voted yes, while seven Republicans voted no. Michigan lost a House seat following the 2010 census. Republicans clinched a 9-5 majority following the 2014 elections, but the House representation as of 2020 includes seven Democrats, six Republicans, and one Independent.

At the state level, Republicans control both the House and Senate, although their margins became smaller following the 2018 election. The legislature did not authorize a state-run health insurance exchange, despite former Gov. Rick Snyder’s preference for that approach. Michigan was among the handful of states that implemented a partnership exchange, which means the state oversees some aspects of the exchange, but the federal government’s HealthCare.gov enrollment platform and call center are used by Michigan residents.

Medicaid expansion in Michigan

Former Governor Rick Snyder, a Republican, pushed for an alternative approach to Medicaid expansion in Michigan and ultimately gained bi-partisan support for Healthy Michigan. Medicaid expansion in Michigan uses the ACA’s eligibility guidelines (ie, up to 138 percent of the poverty level), but the state obtained approval from the Obama Administration to charge premiums for Medicaid plans when enrollees’ incomes are above the poverty level.

Medicaid expansion took effect under the ACA on January 1, 2014, but Michigan was a few months behind due to the state’s waiver process. Enrollment began April 1, 2014, and 770,280 people were enrolled in Healthy Michigan as of August 2020. That was up from 645,504 in July 2019 — a 16% increase. The growth in Medicaid coverage is not surprising, given that so many people have lost their jobs as a result of the COVID-19 pandemic.

Before the pandemic, however, the state sought to reduce enrollment in Medicaid plans with a work requirement. Michigan enacted legislation in 2018 directing the state to seek federal approval for a work requirement. The waiver proposal was submitted to CMS in September 2018, and was granted federal approval in late 2018.

The work requirement took effect in January 2020, but was overturned by a federal judge in March 2020, just prior to the explosion of the COVID-19 pandemic and widespread job losses. The judge’s ruling was not surprising, given that work requirements in Kentucky, Arkansas, and New Hampshire had already been overturned in 2019.

Short-term health insurance in Michigan

Michigan regulations limit short-term health insurance plans to no more than 185 days in duration and prohibit renewal. An applicant can purchase additional short-term plans, but cannot have more than 185 days of short-term health insurance coverage from one insurer in any 365-day period.

Other ACA reform provisions

The ACA’s Consumer Operated and Oriented Plan (CO-OP) Program created a new type of medical insurance company. CO-OPs are non-profit, consumer-run plans, and they were intended to increase choice and competition. In 2014, CO-OPs operated in 23 states, including Michigan Consumer’s Mutual CO-OP.

Within days of 2016 open enrollment beginning in the fall of 2015, Consumers Mutual put out a communication announcing its closure and ceased operations at the end of 2015. Consumers Mutual members who had coverage in 2015 had to select policies from other insurers for 2016.

As of 2020, there were only four CO-OPs remaining, offering plans in five states (Maine, Montana, Idaho, New Mexico, and Wisconsin). In 2021, this will fall to three CO-OPs remaining, as New Mexico Health Connections is closing at the end of 2020.

Medicare coverage and enrollment in Michigan

Medicare enrollment in Michigan stood at more than 2.1 million people as of August 2020. Most are eligible for Medicare due to age, but 17 percent of Michigan Medicare beneficiaries are under 65 and eligible for Medicare because of a long-term disability, end-stage renal disease, or ALS.

Michigan has a Medigap subsidy program to help offset the cost of Medigap coverage for enrollees with modest income. And the state also protects access to certain Medigap plans for people who are disabled and enrolling in Medicare under the age of 65.
