HMO vs. PPO in Michigan: How to Choose for 2027
The difference between an HMO and a PPO comes down to two questions: do you need a referral to see a specialist, and does the plan pay anything if you go out of network? Everything else (premiums, flexibility, paperwork) follows from those two answers.
The four plan types
| Referral needed? | Out-of-network coverage? | Typical premium | |
|---|---|---|---|
| HMO | Usually yes, through a primary care doctor | No, except emergencies | Lowest |
| EPO | Usually no | No, except emergencies | Low to middle |
| POS | Yes | Some, at higher cost | Middle |
| PPO | No | Yes, at higher cost | Highest |
When an HMO makes sense
- Your doctors are all in one health system and you're happy there.
- You don't travel much or have family in other states.
- You want the lowest premium and don't mind getting referrals.
When a PPO is worth paying for
- You see specialists at different hospital systems.
- You travel for work, split time between states, or have kids in college elsewhere.
- You want to book a dermatologist or orthopedist directly, without a gatekeeper.
The catch with marketplace PPOs
Because marketplace plans have to accept everyone, broad PPO networks are expensive for carriers to run, and many have pulled back to HMOs and EPOs tied to one hospital system. In a lot of counties there's no marketplace PPO at all.
Private underwritten plans are where PPOs still live. Outside the marketplace, private shared-network plans are sold in Michigan on leased PPO networks (Cigna, Aetna and PHCS PPO). They're medically underwritten, so they ask health questions and price on age and health instead of income, but you can enroll any month and coverage starts on the 1st. Our deeper guide: where to find a PPO in Michigan.
A simple way to decide
- List every doctor, hospital and prescription you need to keep.
- Look up each one in the plan's directory, and call the office to confirm (see how to find in-network doctors).
- If everything is in one HMO's network, take the cheaper HMO. If not, price the PPO.
- Compare total cost, premium plus likely out-of-pocket spending, not just the premium.
In Michigan, open enrollment for 2027 coverage runs on HealthCare.gov from November 1, 2026 to January 15, 2027. Pick a plan by December 15, 2026 if you want coverage to start January 1, 2027; plans picked after that start later.

Frequently asked questions
Is an HMO or PPO better?
Neither is better for everyone. HMOs cost less but require referrals and don't cover out-of-network care. PPOs cost more but let you see any specialist and pay something out of network.
What is an EPO?
An exclusive provider organization. Like an HMO it doesn't cover out-of-network care except emergencies, but you usually don't need referrals.
Can I get a PPO in Michigan?
Often not on the marketplace in many areas. Private underwritten plans on national PPO networks are the most common way to get one, if you can qualify medically.
