HMO vs PPO is mostly a trade between cost and freedom. An HMO usually charges a lower premium, asks for a primary doctor and referrals, and covers only in-network care except emergencies. A PPO, on the other hand, costs more, but you can see specialists without referrals and get some out-of-network coverage.
- An HMO generally won't cover out-of-network care except in an emergency.
- A PPO lets you use out-of-network doctors without a referral, for an added cost.
- In 2025, the average PPO family premium at work was $28,272, compared with $26,993 across all plan types, according to KFF.
- Only 14% of 2025 Marketplace plans were PPOs, so they can be hard to find when you buy your own coverage.
- Out-of-network costs don't count toward your out-of-pocket limit, which is $12,000 for one person for 2027 coverage.
HMO vs PPO: what is the difference?
Both plan types use a network, which is a group of doctors and hospitals that agree to set prices with the insurer. The difference is how much freedom you get. With an HMO, a primary doctor guides your care, and the network is a hard line. With a PPO, however, you choose your own specialists and can step outside the network.
In exchange for that freedom, PPO premiums usually run higher. So the right pick depends on your doctors, your travel and your budget.
What both plan types share
- Emergency care, whether the hospital is in or out of network
- Preventive care at no cost in network on ACA plans
- A yearly cap on what you pay for covered in-network care
- Lower prices when you stay inside the network

HMO vs PPO network diagram
Picture each plan as a map. Here's how you reach a specialist, and also what happens when you leave the network.
- First, you see your primary doctor
- Then that doctor refers you to an in-network specialist
- Out-of-network visit: you pay the full bill
- Emergency: covered anywhere
- You book any specialist yourself
- Also, no referral slip needed
- Out-of-network visit: the plan pays part
- Emergency: covered anywhere
A specialist visit, step by step
Say you need a dermatologist. Here's how an HMO routes that visit:
- Book your primary doctor
First, your primary care doctor looks at the problem and decides on next steps.
- Get the referral
Next, the office sends a referral to an in-network dermatologist.
- See the specialist
Then you pay your normal copay or coinsurance for that visit.
With a PPO, by contrast, you'd skip the first two steps and simply call the dermatologist you want.
What happens out of network
Outside the network, an HMO pays nothing for routine care. A PPO pays part, but the doctor can bill you for the gap between their charge and the plan's allowed amount. Fortunately, the No Surprises Act blocks most surprise bills for emergency care. It also limits bills from out-of-network doctors who treat you at an in-network hospital.
What is an HMO plan?
A health maintenance organization (HMO) usually limits coverage to doctors who work for or contract with the plan. You pick a primary care doctor, who handles most of your care. As a result, care stays coordinated, and costs stay lower.
HMO pros and cons
- Lower premiums than most PPOs
- One doctor who coordinates your care
- Little claim paperwork, because doctors bill the plan
- Referrals for most specialists
- No routine out-of-network coverage
- Smaller networks than PPOs in some areas
Is an HMO better than a PPO for you?
An HMO often wins when every doctor you use sits in its network and you stay close to home. Before you choose one, follow our steps on how to confirm a doctor takes your plan.
What is a PPO plan?
A preferred provider organization (PPO) lets you use doctors and hospitals outside its network without a referral, for an added cost. Still, you pay less in network. Plus, you don't need a primary doctor to manage your care.
PPO pros and cons
- No referrals for specialists
- Some coverage outside the network
- Larger networks than HMOs, on average
- Higher premiums than an HMO
- Possible balance bills from out-of-network doctors
- More claim paperwork when you go outside
When a PPO beats an HMO
A PPO makes sense if you travel often, live in two states or see several specialists. It also helps when you want to keep a doctor outside the network. Even so, outside care still costs more, so learn what you pay outside your plan's network first.
A licensed Vivna agent can search your doctors, hospital and drugs in every HMO and PPO near you, at no cost to you.
HMO vs PPO comparison chart
Here's the HMO vs PPO comparison side by side. Rules vary by carrier, so treat this as typical, not exact.
| Your situation | HMO plan | PPO plan |
|---|---|---|
| Lowest monthly premium | Usually lower | Higher than an HMO |
| One doctor coordinating care | Built in | Optional |
| Seeing specialists often | Referral needed | No referral needed |
| Out-of-network coverage | Emergencies only | Covered at a higher cost |
| Travel or living in two states | Local network, so less help when you travel | Often a wider network |
| Family uses local doctors | Strong fit | Works, but costs more |
| Claim paperwork | Little to file, since doctors bill the plan | More when you go outside |
HMO vs PPO costs compared
At work, KFF's 2025 survey shows the PPO premium gap clearly. However, your share depends on what your employer pays.
Also, out-of-network spending in a PPO doesn't count toward your yearly cap. Our guide on how your yearly spending cap works explains why.
Where EPO and POS plans fit
Two hybrids also sit in between. An EPO skips referrals like a PPO but stays in network like an HMO. Meanwhile, a POS plan uses referrals like an HMO but pays part of outside care. See when an EPO or POS plan makes sense.
PPO vs HMO: which has more doctors?
In general, PPOs reach more doctors. According to KFF data reported by RWJF, the average PPO enrollee could reach 53% of area doctors. By comparison, HMO enrollees could reach 37%, and EPO enrollees 38%.
How to check a network
Still, a big network only matters if it includes your doctors. So search each doctor in the carrier's directory, confirm your hospital, check your prescriptions, and then call the office. Our network search links for every carrier make that faster. For the bigger picture, read how network size changes what you pay.
Why PPO plans are harder to find than HMO plans
If you buy your own coverage, PPOs can be scarce. For example, RWJF found that only 14% of 2025 Marketplace plans were PPOs. In fact, 37% of U.S. residents live in a state with no Marketplace PPO at all.
Off the Marketplace, PPOs made up 23% of plans in 2025, up from 19% in 2023. Keep in mind that off-Marketplace plans don't qualify for premium tax credits. So a subsidized HMO often costs far less than an unsubsidized PPO.
Smart alternatives to a PPO
- An EPO with a broad network that includes your doctors
- A POS plan, when your area has one
- An HMO built around your current doctors and hospital
Also, each carrier builds its networks differently. For example, compare UnitedHealthcare's individual plan lineup, then shop ACA and private plans in your ZIP code.
HMO vs PPO: which plan fits your situation?
Neither plan wins for everyone, so match the plan to how you really use care.
An HMO usually costs less for the same care.
A PPO gives you coverage away from home.
A PPO or an EPO skips the referral step.
Start with an HMO, then check its network.
Tips for families
First, confirm that your pediatrician and any children's specialists are in network. Next, find the nearest in-network hospital with a children's unit. Then compare what families really pay each year for both plan types.
Ask for the network name, not just the carrier. One carrier can sell an HMO and a PPO with different doctor lists in the same county. So we search your doctors in the exact network on the plan you're about to pick.
Pay for flexibility only if you'll use it.The rule our licensed agents repeat most

HMO vs PPO: FAQs
What is the main difference between HMO and PPO plans?
An HMO asks you to use a primary doctor for referrals and covers only in-network care, except emergencies. A PPO, by contrast, lets you see specialists without referrals and pays part of out-of-network care. In return, PPO premiums usually run higher. So the choice comes down to cost versus freedom.
Is an HMO cheaper than a PPO?
Usually, yes. HMO premiums tend to run lower, and in-network copays are often lower too. At work, KFF found the average PPO family premium was $28,272 in 2025, above the $26,993 average for all plans. Still, compare the full yearly cost, including the deductible, for the care you expect. For more side-by-side picks, see our guide to the best health insurance plans.
Do PPO plans require referrals?
No, most PPO plans don't require referrals to see specialists. However, some services, such as surgery or advanced imaging, may still need prior approval from the plan. So check the plan's summary of benefits, or ask your agent, before you book a big procedure.
Does an HMO cover out-of-network doctors?
Generally, no. An HMO won't pay for routine out-of-network care, so you'd owe the whole bill. Emergencies are the main exception. Also, the No Surprises Act limits surprise bills when an out-of-network doctor treats you at an in-network hospital.
Is an HMO or PPO better for families?
It depends on your family's doctors. If your pediatrician, specialists and hospital sit in one local network, an HMO often saves money. On the other hand, a PPO may fit better if a child attends college out of state or sees out-of-network specialists. Either way, check every family member's doctors first.
Can an agent help me compare HMO and PPO plans?
Yes. A licensed agent can search your doctors and drugs in each network and price a full year of care. At Vivna, our agents compare plans from 50+ carriers, and our help costs you nothing. Plus, the plan price stays the same whether you buy through us or directly.
