Priority Health Medicare Advantage: Michigan's Integrated Insurer

Priority Health is Michigan's second-largest health plan and part of Corewell Health, the integrated system formed by the merger of Spectrum Health and Beaumont Health. Its defining feature is that integration, since Priority Health is the insurance side of a system that also owns hospitals and employs doctors across Michigan. It has a solid quality reputation and good star ratings in its markets, and if you live in Michigan it is one of the first Medicare Advantage names you will encounter, so it is worth understanding what that integration does well.

Bryce's Take

Priority Health is a strong Michigan option, and the Corewell integration is a real plus when your care is inside that system, because the plan and the providers are part of the same organization. It has the scale and the ratings to be taken seriously, and I am happy to put it in the comparison for Michigan clients. As always, I check the star rating for the exact plan in your county and confirm your doctors participate before I recommend it, since the integration only helps you if your providers are actually in it.

Overview of Priority Health

Priority Health offers Medicare Advantage HMO and PPO plans across Michigan, backed by the Corewell Health system's hospitals and physicians. As the insurance arm of an integrated payer and provider, its plans are closely connected to Corewell facilities and doctors, which supports coordinated care. Plans include the dental, vision, hearing, and Part D coverage common to Medicare Advantage, along with the broad Michigan networks that come with a large statewide system. The footprint is regional, centered on Michigan, so availability is specific to the counties Priority Health serves.

Strengths

Priority Health's biggest strength is its integration with Corewell Health, which pairs the plan with a large statewide system of hospitals and doctors, supporting coordinated care and deep local networks. It is Michigan's second-largest health plan, so it has real scale, contracting leverage, and stability, and its star ratings and quality reputation in the state have generally been strong. For members whose care is inside the Corewell system, the connection between plan and provider can smooth the experience in a way a standalone insurer cannot match.

Weaknesses

Priority Health is a regional carrier, so it is essentially a Michigan option, and its integrated advantages are strongest where care is delivered inside the Corewell system rather than everywhere it contracts. Its plans carry the usual HMO and PPO network structures, referrals, and prior authorization common to Medicare Advantage. Star ratings and benefits vary by specific plan and county, and the integration naturally steers members toward Corewell facilities, so for someone whose doctors are outside that system it may be a weaker fit.

How big is Priority Health, really?

Priority Health is Michigan's second-largest health plan, covering a large share of the state across its commercial, Medicaid, and Medicare lines, and it is the insurance arm of Corewell Health, one of the largest health systems in Michigan. Its membership is concentrated in Michigan rather than spread nationally. The practical takeaway is a substantial, established, integrated regional insurer rather than a national giant. Financial figures for the system are approximate, reflect where things stood as of 2024, and shift every year, so treat any numbers as a sense of scale rather than precise current figures.

What members actually say

Priority Health is well regarded in Michigan, helped by its scale, its broad statewide networks, and the coordination that comes with the Corewell integration. Member sentiment in its core markets tends to be solid, and its star ratings have generally been strong, though they vary by specific plan and county, so it is worth checking the rating for the exact plan you are considering. The most common concerns are the usual HMO-style ones, namely network limits, referrals, and prior authorization, along with the natural steering toward Corewell facilities.

The trend: is Priority Health adding or cutting benefits?

Priority Health is a large, integrated Michigan insurer with solid ratings, which has helped it hold up better than some carriers, but it is not immune to the wider pressures on Medicare Advantage. Like nearly every carrier it has been adjusting benefits for the 2025 and 2026 plan years under the industry-wide squeeze created by CMS rate changes, the phase-in of the v28 risk-adjustment model, and rising medical costs, pressures that pushed carriers broadly to trim supplemental benefits, raise out-of-pocket maximums, and in some cases exit counties. Because plan benefits reset every Annual Enrollment Period, the only reliable way to know what a specific Priority Health plan offers for the coming year is to compare its current details for your county, which is what a call with Bryce is for.

Who Priority Health tends to fit well

Priority Health fits members in Michigan who use Corewell doctors and hospitals and value the coordination that comes with an integrated system, and it is especially compelling when your care is already inside Corewell. It is essentially a Michigan-only option, and it is a weaker fit for people whose doctors are outside the Corewell system or who want a broad national network, for whom another plan or Original Medicare with a Medigap plan may be better.
