Ten insurers offer plans for 2023; Overall average rate increase is 5.5%

Michigan exchange overview

Michigan continues to have one of the most robust health insurance exchanges in the country, with ten carriers offering coverage for 2023. 

For 2023, state regulators approved premiums that amount to an overall average rate increase of 5.5% for Michigan’s individual market insurers. 

Frequently asked questions about Michigan's ACA marketplace

Michigan has a state-federal partnership exchange; the state oversees plan management, but is used for enrollment.

Bipartisan legislation (HB6112) was introduced in 2022 that would direct the state to conduct a study on the impacts of switching to a fully state-run exchange, and potentially make that move at some point in the future. That bill had not advanced as of July 2022. And even if it passes, the transition to a state-run exchange would be a multi-year process. 

The open enrollment period for individual/family coverage runs from November 1,  to January 15 in Michigan. Enrollments completed by December 15 will have coverage effective January 1, while enrollments completed between December 16 and January 15 will have coverage effective February 1.

Outside of open enrollment, a qualifying event is necessary to enroll or make changes to your coverage.

For 2023 coverage, there are ten insurers that offer exchange plans in Michigan.

In most of Michigan, at least four insurers are offering plans in the exchange for 2023, although there are just two participating insurers in upper Michigan.

The following insurers offer plans in the Michigan exchange for 2023, with plan availability varying from one location to another:

Time/Assurant and Consumer Mutual Insurance of Michigan both left the Michigan exchange at the end of 2015. Consumers Mutual was an ACA-created CO-OP that insured 28,000 members in 2015. They announced on November 2 — the day after the start of open enrollment for 2016 plans — that they would not sell policies on Michigan’s exchange in 2016, and that their existing on-exchange members would need to switch to a different carrier for 2016.

According to Crain’s Detroit Business, only a little more than a fifth of Consumers Mutual’s members purchased their plans in the exchange in 2015, and at that point, there was a possibility that the remaining 80 percent of the enrollees might be able to keep their plans, with the CO-OP continuing to offer plans outside the exchange.

But that hope was short-lived. By November 4, the announcement on Consumers Mutual’s website indicated that all enrollees — including those who had purchased their plans outside the exchange — would need to seek new coverage for 2016, and that the CO-OP would wind down its operations by the end of 2015.

Consumers Mutual enrolled just 29 percent of their projected membership in 2014, and had net losses of $16 million during the first year of operations. They were the 12th CO-OP (out of 23) to fail, and were among the majority whose closing was attributed to the fact that the federal government only paid out 12.6 percent of the risk corridor payments that were owed to carriers based on losses in 2014.

After Consumers Mutual folded and Time exited the market the Michigan exchange had 14 carriers offering coverage in 2016. That declined to ten for 2017 (although some of the decrease was due to PPO entities leaving the exchange, while their HMO sister companies remained in the exchange). The number of exchange insurers had dropped to eight by 2018, but grew to nine in 2019 when Oscar joined the exchange in Michigan. All nine insurers have filed plans to remain in the exchange for 2020. Insurer participation tends to be most robust in the southeastern part of the state, and less robust in Upper Michigan.

UnitedHealthcare exited the individual market in Michigan at the end of 2016, as was the case in most of the states where they offered plans in the exchange in 2016.

Harbor Health Plan exited the exchange at the end of 2016. They continued to offer one bronze plan off-exchange in 2017.

Priority Health Insurance Company, which offered PPO and POS plans in 2016, switched to only offering small group plans for 2017, and only outside the exchange. But Priority Health, which is a separate entity, has continued to offer individual and small group plans, on and off the exchange.

Health Alliance also dropped their PPOs, continued to offer more than 45 Personal Alliance HMO plans, both on and off-exchange (the PPOs were offered via Alliance Health and Life Insurance Company, which is a subsidiary of Health Alliance; Alliance Health and Life Insurance Company plans are no longer offered on the Michigan exchange). Blue Cross Blue Shield of Michigan was the only carrier still offering PPO plans through the Michigan exchange by 2017.

Humana dropped their individual PPO plans in Michigan at the end of 2016, but that only impacted the off-exchange market, as Humana’s on-exchange plans were already HMOs.

Humana exited the individual market entirely at the end of 2017, however, nationwide. In 2017, Humana’s coverage area included most of southeast Michigan, as well as Kalamazoo County and Kent County.

Health Alliance Plan (HAP) announced in September 2017 that they would not offer plans in the Michigan exchange for 2018, although their off-exchange plans continued to be available. HAP’s exit announcement noted that 9,100 members would have to find new plans. Their rate filing from earlier in the summer (when they were still planning to participate in the exchange) said that it would impact 17,000 members, but those with off-exchange coverage were able to keep their plans for 2018 if they wished to do so (HAP had 650,000 members in total in 2017, virtually all of whom had Medicare, Medicaid, or employer-sponsored coverage and were therefore not affected at all by the insurer’s decision to exit the exchange).

HAP noted in their announcement that the uncertainty caused by the Trump Administration and GOP-led Congress played a primary role in their decision to exit the exchange. They explained that the decision was based on “many uncertainties related to premium stabilization programs, enforcement of the individual mandate and not knowing whether the federal government will continue to fund cost-sharing reductions (CSRs).”

Oscar Health joined the exchange in Michigan for 2019 (in Wayne, Macomb, Oakland, St. Claire, Livingston, and Washtenaw counties), and all nine insurers continued to offer plans in the exchange for 2020 and 2021.

For 2022, Total Health Care has merged with Priority Health, but two new insurers are offering plans in the exchange: US Health and Life is new for 2022, and UnitedHealthcare has returned after a five-year hiatus. So there are a total of ten insurers offering exchange plans in Michigan for 2022. The two off-exchange-only insurers (Alliance Health and Life, and Health Alliance Plan) are continuing to offer off-exchange plans for 2022.

There are ten insurers that offer individual/family coverage through the health insurance exchange in Michigan. For 2023, the state’s insurers (including two that only offer coverage outside the exchange) have implemented an overall average rate increase of 5.5% (slightly lower than insurers initially proposed), with the following rate changes for each insurer:

  • Blue Care Network (the HMO subsidiary of Blue Cross Blue Shield of Michigan): 8.1% increase
  • Blue Cross Blue Shield of Michigan: 3.1% decrease
  • McLaren Health Plan: 12.3% increase
  • Meridian (Ambetter as of 2021): 12.6% increase
  • Molina: 3.6% increase
  • Oscar Health: 0.1% increase
  • Physicians Health Plan: 10.9% increase
  • Priority Health (HMO and POS): 6.7% increase (Priority Health has purchased Total Health Care)
  • UnitedHealthcare Community Plan: 10.1% increase
  • US Health and Life Insurance Company: 2% decrease

Alliance Health & Life, and Health Alliance Plan, both of which only offer coverage outside the exchange in Michigan, have average rate increases of 10.3% and 2%, respectively. Between the two of them, they have about 5,000 enrollees (the total individual market in Michigan has about 360,000 enrollees, so the ten exchange insurers have virtually all of the market share, although some of their enrollees do have off-exchange coverage) 

Although Michigan’s overall average rate change for 2023 individual/family coverage is an increase of 5.5%, overall average rate changes don’t paint a full picture, for several reasons:

  • They only apply to full-price premiums, and most exchange enrollees receive premium subsidies. For subsidized enrollees, after-subsidy rate changes also depend on how the subsidy amount changes from one year to the next. For 2023, subsidies continue to be larger than they were prior to 2021, thanks to the American Rescue Plan’s subsidy enhancements, which were extended through 2o25 by the Inflation Reduction Act.
  • They don’t account for the fact that rates increase with age. So even if your insurer doesn’t change its rates at all for the coming year, your price will still go up just because you’re a year older (if you receive subsidies, the subsidies will grow to keep pace with the age-related premium increases; subsidies for older enrollees are larger than subsidies for younger enrollees).
  • They lump all insurers and plans together. Insurers have differing coverage areas and plan availability, which means rates in one area can change more or less than rates in another area of the same state.

Numerous factors have affected premiums over the years, including the risk corridor shortfalls, the end of the ACA’s reinsurance program after 2016, the repeal of the individual mandate at the end of 2018 (and public perception that it wasn’t being enforced before that), the expansion of short-term plans, whether or not a state has expanded Medicaid, and overall utilization of health care. Here’s a look at how premiums (before subsidies are applied) in Michigan’s individual market have changed over the years.

2015: Average rate decrease of 1%. Average premiums in Michigan’s exchange decreased by 1% for 2015.

2016: Average increase of 6.5%. In August 2015, the Michigan Department of Insurance and Financial Services (DIFS) announced that the weighted average rate increase in the individual market for 2016 would be 6.5%, although the average rates increase dropped lower than that once Consumers Mutual exited the market. The CO-OP had by far the highest average rate increase for 2016 of any of the exchange carriers in Michigan, at 20.5% (the next highest was UnitedHealthcare, at 14.7%), but the new rates never took effect since members had to switch to a different carrier for 2016. Michigan’s average rate increase fo 2016 was about half as much as the average rate increases nationwide for 2016.

2017: Average rate increas of 16.7%. The overall average rate increase in Michigan’s individual market was 16.7% for 2017 (including carriers that only offer off-exchange plans). But the average benchmark plan premium (second-lowest-cost silver plan) was just 7% higher in 2017 than it was for 2016 in Michigan. The state is one of only nine that had single-digit increases in their average benchmark plan premiums for 2017. Subsidies are based on the cost of the benchmark plan, so they rose modestly in 2017 in Michigan.

2018: Average rate increase of 25.5%. Due to the uncertainty over whether cost-sharing reductions (CSR) would be funded in 2018, the Michigan Department of Insurance required insurers to file two sets of rates for 2018 — one that assumed that cost-sharing reductions would be funded, and one that assumed they wouldn’t. Ultimately, the Trump administration cut off funding for CSR in October 2017, and insurers implemented the rates based on that scenario, with the cost of CSR added to silver plan premiums.

That amounted to a weighted average rate increase of 25.5%, but it would have been 17.6% if CSR funding had not been eliminated (a significant portion of this increase was due to overall market uncertainty cause by the Trump administration and GOP legislative efforts to undermine the ACA in 2017). The additional premium increase to cover the cost of CSR was added to silver plan premiums, and in most cases, Michigan residents were able to buy off-exchange silver plans that didn’t have the added cost of CSR built into their premiums. That’s useful for people who don’t get premium subsidies, but for people who do get premium subsidies, the subsidies grew significantly for 2018 to offset the higher silver plan premiums.

2019: Average rate increase of 1.7%. Nine insurers offered plans through Michigan’s exchange for 2019, plus two more that offered coverage outside the exchange. Across all 11 insurers, the average rate increase for 2019 was about 1.7%.

2020: Average rate decrease of 2.5%. Across the 11 insurers, there was an overall average premium decrease of 2.5% for 2020. But average benchmark premiums in Michigan dropped by 6% for 2020, and premium subsidies are based on benchmark premiums. When average benchmark premiums decline more sharply than overall average premiums, the result is higher after-subsidy premiums for some enrollees. This reduced affordability could be part of the reason Michigan’s exchange enrollment declined from 2019 to 2020.

2021: Average rate increase of 1.1%. Across the full individual market, average premiums increased by just 1.1% for 2021 (slightly less than the average increase of 1.3 percent that the insurers had proposed)

2022: Average rate increase of 4.7%. Across the full individual market, including the two off-exchange insurers, the average rate increase was 4.7% for 2022. Two new insurers joined the exchange for 2022: US Health and Life, and UnitedHealthcare.

303,550 people enrolled in health plans through the Michigan exchange during the open enrollment period for 2022 coverage. This was the highest enrollment had been since 2017.

Background on Michigan’s exchange efforts

Former Gov. Rick Snyder, a Republican, supported a state-run exchange for Michigan. However, he did not have the support of enough fellow Republicans to move ahead.

The Michigan attorney general joined 25 other states in challenging the Affordable Care Act. The Senate passed a bill to authorize a state-run exchange, but the bill was voted down by the House’s Health Policy committee and didn’t get a floor vote.

Eventually, the state moved ahead with a state-federal partnership. Michigan is responsible for plan management, but left all other functions to the federal government.

When the King v. Burwell case was pending before the U.S. Supreme Court,  Snyder again broached the topic of a state-run exchange to ensure Michigan residents have continued access to subsidies to pay for health insurance. Ultimately, the Court ruled that subsidies would continue to be available in every state, and Michigan did not have to consider a back-up plan to create a state-run exchange.

Michigan did accept federal funding to expand Medicaid under the ACA. From late 2013 until the spring of 2022, total enrollment in Medicaid and CHIP in Michigan grew by 52% — with enrollment up by nearly a million people. The enrollment growth was largely driven by Medicaid expansion and the COVID pandemic (including the Families First Coronavirus Response Act, which has paused Medicaid eligibility redeterminations throughout the COVID public health emergency).
