How an EPO works

An EPO contracts with a group of doctors, hospitals and other providers. When you use them, the plan pays its share after your deductible, copays and coinsurance, just like any other plan. When you go outside that group for non-emergency care, the plan pays nothing, and the provider can bill you whatever it charges.

Most EPOs let you see an in-network specialist without asking a primary care doctor first. That makes them feel a bit like a PPO inside the network. Outside the network, they work like a strict HMO.

EPO vs. HMO vs. PPO vs. POS

Plan type	Out-of-network care	Referral to see a specialist	Premiums
EPO	Not covered, except emergencies	Usually not needed	Often lower
HMO	Not covered, except emergencies	Usually needed	Often lower
POS	Covered at a higher cost	Needed	Usually in between
PPO	Covered at a higher cost	Not needed	Often higher

For a closer look at the other types, see HMO health plans, PPO health plans and what is better, a PPO or an HMO.

How common are EPOs?

Very common if you buy your own insurance. In 2024, HMOs and EPOs made up 79% of plans offered on the ACA Marketplaces, up from 42% in 2014, and the number of EPO plans had tripled. By 2025, only 14% of Marketplace plans were PPOs, and 37% of Americans lived in a state with no Marketplace PPO at all.

Employer plans lean the other way. In 2025, 46% of workers with job-based coverage were in a PPO, while 12% were in an HMO or EPO.

Pros and cons

Why people pick an EPO:

• Lower premiums than a comparable PPO in many areas
• No referrals needed to see most in-network specialists
• Predictable costs as long as you stay in network

The downsides:

• No coverage for planned out-of-network care, even if you’d pay more
• Networks can be small, and they can change from year to year
• Less useful if you travel a lot or have family in another state

Network size matters more than the label. KFF found that in almost half of counties with both options, at least one HMO or EPO plan had a broader doctor network than a PPO plan. And studies of Marketplace plans have found that narrow-network plans tend to cost less. See comparing health insurance to find the best-fit plan.

When an EPO makes sense

An EPO is a good fit if your doctors and nearest hospital are in the network, you mostly get care close to home, and you’d rather have a lower premium than out-of-network coverage.

Think twice if you want to keep a doctor who isn’t in the network, you split time between two states, you have a child in college out of state, or you need a specialist at a particular hospital. In those cases, a PPO or a plan with a national network may be worth the higher premium. See can I use my health insurance out of state.

What’s still covered out of network

Even with an EPO, you’re protected in a few situations:

• Emergencies. Plans can’t require prior approval for emergency care and can’t charge you more for out-of-network emergency care than in-network. See will health insurance cover emergency room visits.
• Out-of-network doctors at an in-network hospital. Under the No Surprises Act, anesthesiologists, radiologists, emergency doctors and similar providers you didn’t choose can’t send you a surprise bill for more than your in-network cost sharing.
• Air ambulances. Surprise billing protections cover air ambulance rides. Ground ambulances generally aren’t covered by the federal law.
• Wrong directory listings. If you relied on a plan’s provider directory that wrongly listed a provider as in network, your cost sharing should be limited to the in-network amount.

For other surprise charges, see what to do about out-of-network costs.

How to check an EPO’s network before you enroll

1. Search the plan’s online provider directory for each doctor, specialist and hospital you use.
2. Call each office and ask if they take that specific plan next year, not just the insurance company.
3. Check the plan’s pharmacy network and drug list.
4. Look at which urgent care centers and hospitals near you are included.

Frequently asked questions

Does an EPO cover out-of-network care?

Only in emergencies and a few situations protected by federal law, like surprise bills from out-of-network doctors at an in-network hospital. Planned out-of-network care isn’t covered.

Do you need a referral with an EPO?

Usually not. Most EPOs let you see in-network specialists on your own, but some require referrals for certain services, so check your plan documents.

Is an EPO better than a PPO?

It depends on your doctors and budget. An EPO usually costs less, but a PPO pays something toward out-of-network care. If your doctors are all in the EPO’s network, the EPO is often the better deal.

Can I use my EPO in another state?

Only with providers in the plan’s network. Some EPOs have national networks, but many are local. Emergency care is covered anywhere.
