HMO vs PPO vs EPO vs POS: How the Four Main Health Plan Networks Compare
Every health insurance plan uses one of four network types. The network decides which doctors you can see, whether you need a referral, and how much you pay out of pocket. This guide breaks down HMO, PPO, EPO, and POS plans side by side so you can pick the structure that fits your household.
HMO vs PPO vs EPO vs POS at a Glance
This side-by-side comparison shows how the four network types differ on the things that matter most: which doctors you can see, whether you need a referral, out-of-network coverage, and typical cost.
| Plan Type | Network | Referral? | Out-of-Network | Typical Cost | Best For |
|---|---|---|---|---|---|
| HMO | Must use in-network doctors and hospitals | PCP referral usually required for specialists | Not covered (except emergencies) | Lowest premiums, lowest out-of-pocket costs | Members who want the lowest monthly cost and are fine with a smaller network |
| PPO | Large in-network and out-of-network options | No referral needed for specialists | Covered at a higher cost-share | Higher premiums, more flexible cost-sharing | Members who want maximum choice of doctors and travel often |
| EPO | Must use in-network doctors and hospitals | No referral needed for specialists | Not covered (except emergencies) | Mid-range premiums, mid-range out-of-pocket costs | Members who want PPO-style freedom to see specialists without a referral, at a lower price |
| POS | In-network preferred, out-of-network allowed | PCP referral usually required for specialists | Covered at a higher cost-share | Mid-range premiums, higher out-of-network costs | Members who want the coordinated care of an HMO with occasional out-of-network access |
Costs and rules vary by carrier, state, and specific plan. Always confirm your doctors are in-network before enrolling.
What is an HMO health insurance plan?
An HMO (Health Maintenance Organization) plan builds coverage around a specific network of doctors and hospitals. You choose a primary care physician (PCP) who coordinates your care and refers you to in-network specialists when needed. Care received outside the network is generally not covered, except for true emergencies.
HMOs tend to have the lowest monthly premiums and predictable copays because the insurer negotiates set rates with a defined group of providers. If you are comfortable staying in-network and letting a PCP guide your care, an HMO usually offers the best price.
Strengths
- Lowest monthly premiums of the four network types
- Low, predictable copays for in-network care
- PCP helps coordinate specialists, tests, and prescriptions
Tradeoffs
- No coverage for out-of-network care (except emergencies)
- Referrals required before seeing most specialists
- Smaller provider list, especially in rural counties
What is a PPO health insurance plan?
A PPO (Preferred Provider Organization) plan gives you the widest choice of doctors. You can see any in-network provider without a referral, and you still get partial coverage if you go out of network. That flexibility is why PPOs are popular with people who travel, have complex health needs, or want to keep specific specialists.
The tradeoff is cost. PPOs typically have the highest premiums, higher deductibles, and larger out-of-pocket maximums than HMOs or EPOs with a similar metal level.
Strengths
- No referral required to see specialists
- Out-of-network care is partially covered
- Large provider networks, often nationwide
Tradeoffs
- Highest premiums of the four network types
- Deductibles and coinsurance are often higher
- Out-of-network care can still be expensive after coverage
What is an EPO health insurance plan?
An EPO (Exclusive Provider Organization) plan combines features of an HMO and a PPO. Like an HMO, it restricts coverage to in-network providers, so out-of-network care is generally not paid for. Like a PPO, it does not require a PCP referral to see a specialist.
EPOs are common on the ACA Marketplace because they let insurers offer PPO-style flexibility at HMO-style prices. If your preferred doctors are already in the plan's network, an EPO is often the best value of the four network types.
Strengths
- No referral required to see specialists
- Premiums lower than a comparable PPO
- Common on the ACA Marketplace in most states
Tradeoffs
- No coverage for out-of-network care (except emergencies)
- Networks can be narrower than a PPO
- Out-of-area care requires planning ahead
What is a POS health insurance plan?
A POS (Point of Service) plan is a hybrid between an HMO and a PPO. You pick a PCP who manages your care and provides referrals, but unlike an HMO, you can also go out of network. Out-of-network care is covered, though at a higher cost-share and usually with a separate deductible.
POS plans are less common than the other three network types but can be a good fit if you want the coordinated care and lower in-network cost of an HMO with the safety net of out-of-network coverage.
Strengths
- In-network premiums competitive with HMOs
- Out-of-network care is covered (at a higher cost)
- PCP coordinates your overall care plan
Tradeoffs
- Referrals usually required for specialists
- Out-of-network deductibles and coinsurance are higher
- Fewer POS plans available on some state exchanges
How to Choose the Right Network for Your Household
Start with the doctors and hospitals you already use. Look them up in each plan's network directory before you compare premiums. A cheap plan is not a bargain if your primary care doctor is not in-network.
- List your must-have providers. Include your PCP, any current specialists, and the hospital system you prefer.
- Decide how much flexibility you need. If you travel or split time between states, favor a PPO or POS. If you stay local, an HMO or EPO usually costs less.
- Add up the full cost. Compare the monthly premium plus the deductible, typical copays, and the out-of-pocket maximum, not just the premium alone.
- Check prescription coverage. Confirm your medications are on the plan's formulary at a tier you can afford.
- Talk to a licensed agent. A TruePath agent will confirm your doctors are in-network, compare subsidies, and match you to the plan structure that fits your budget.

Frequently Asked Questions
Which is cheaper, HMO or PPO?
HMOs are almost always cheaper than PPOs at the same metal level. HMOs restrict care to a defined network and often require referrals, which lets insurers negotiate lower rates. PPOs charge more in exchange for broader networks, out-of-network coverage, and no referral requirement.
What is the difference between an EPO and a PPO?
Both an EPO and a PPO let you see specialists without a referral. The key difference is out-of-network coverage: a PPO pays part of the cost when you go out of network, while an EPO generally does not cover out-of-network care except in emergencies. That is why EPOs typically cost less than PPOs.
Do EPO plans require a referral?
No. EPO plans do not require a primary care referral to see a specialist. You can book directly with any specialist inside the plan's network. This is one of the main reasons people choose an EPO over an HMO.
Is a POS plan the same as an HMO?
No, but they are similar. A POS plan uses a PCP and referrals like an HMO, but it also covers care from out-of-network providers at a higher cost-share. An HMO does not cover out-of-network care at all, except in emergencies.
Which network type is best for people who travel?
A PPO is usually best for frequent travelers because it covers care both in and out of network. A POS plan is a lighter-weight alternative that also allows out-of-network care. HMOs and EPOs are generally not recommended for people who need coverage across many regions.
Can I switch from an HMO to a PPO?
You can change your plan network during Open Enrollment or a Special Enrollment Period triggered by a qualifying life event such as marriage, a new baby, or loss of other coverage. A licensed agent can review your options and make sure your preferred doctors are in the new plan's network before you switch.
Not Sure Which Network Is Right for You?
A licensed TruePath agent will confirm your doctors are in-network, compare HMO, PPO, EPO, and POS options side by side, and apply every subsidy you qualify for.
