🚀 Fast Facts: EPO vs. PPO
- An EPO covers care only from in-network providers, except in emergencies; a PPO also pays part of out-of-network care
- EPOs usually have lower premiums: 24% lower employee-only contributions than PPOs in a 2024 Mercer study of 115 large employers
- Many EPOs don't require referrals to see a specialist, though gated EPOs do
- Either plan type can qualify for an HSA if it meets the IRS HDHP rules
The EPO vs PPO choice comes down to one trade-off: an exclusive provider organization (EPO) usually costs less but covers care only inside the plan's network, while a preferred provider organization (PPO) costs more but still pays part of the bill when you see out-of-network providers. Both are common types of health insurance, and the right health plan depends on your doctors, how often you travel, and how much you can pay each month.
This guide explains how each plan works, how costs compare, and who each plan type tends to fit.
What is an EPO health plan?
An exclusive provider organization is a managed care plan where services are covered only if you go to doctors, specialists, or hospitals in the plan's network, except in an emergency, according to HealthCare.gov. An EPO health plan sits between a health maintenance organization (HMO) and a PPO: it limits coverage to the network like an HMO, but many EPO plans let you see a specialist without a referral.
- In-network only. EPO plans cover care from participating providers. If you choose out-of-network providers for non-emergency care, you generally pay the full cost yourself.
- Usually no referral. Many EPO plans don't require a referral to see a specialist. Some "gated" EPO plans require you to choose a primary care provider who coordinates referrals; non-gated plans skip that step.
- Lower cost. EPO plans typically charge lower monthly premiums than PPO plans from the same employer (see the cost section below).
Example: if your dermatologist is in the EPO network, your plan covers the visit at negotiated rates. If the same dermatologist is outside the EPO network, the visit isn't covered at all unless it's an emergency.
What is a PPO plan?
A PPO plan is a type of health plan that contracts with a network of preferred providers. You pay less when you use in-network providers, but you can also see doctors, hospitals, and providers outside the network for an additional cost, according to HealthCare.gov.
- Out-of-network coverage. A PPO pays part of the cost of out-of-network care, usually with a separate or higher deductible and higher coinsurance.
- No primary care physician requirement. PPO plans generally don't make you choose a primary care physician or get a referral to see a specialist.
- Higher premiums. You pay more each month for the broad network and more flexibility.
- The most common employer plan. 46% of covered workers were enrolled in a PPO in 2025, according to the KFF 2025 Employer Health Benefits Survey. (KFF groups EPOs with HMOs.)
EPO vs PPO at a glance
Factor | EPO | PPO |
Network | In-network providers only, except emergencies | In-network and out-of-network providers |
Out-of-network care | Generally not covered (emergency services only) | Partly covered, at a higher cost to you |
Referral to see a specialist | Usually not required (gated EPOs may require one) | Not required |
Primary care physician | Sometimes required | Not required |
Monthly premiums | Usually lower | Usually higher |
Can be an HDHP for an HSA? | Yes, if it meets IRS HDHP rules | Yes, if it meets IRS HDHP rules |

Network flexibility: the biggest difference
The plan's network is the main difference between an EPO and a PPO. Both use a network of health care providers. What changes is what happens when you leave it.
With an EPO, the EPO network is the plan's coverage: non-emergency medical services from out-of-network providers are generally not covered, so you pay out of pocket. With a PPO, out-of-network care still gets partial coverage, so you can keep a long-time specialist or use a hospital in another state at a higher cost.
That matters most if you:
- Have a doctor or specialist you want to keep who isn't in the EPO network
- Travel often, split time between states, or have a child at college in another state
- Expect to need specialized care at health care facilities outside your area
If all your doctors and hospitals are in the EPO network and you mostly access care close to home, the network requirements may never affect you.
Cost: premiums, deductibles, and out-of-pocket costs
Monthly premiums are only part of the cost. Compare the full picture: premium, deductible, copays, coinsurance, and the out-of-pocket maximum.
In a 2024 Mercer analysis of 115 large employers that offer EPOs:
- Employee premium contributions were 24% lower for employee-only coverage and 17% lower for family coverage in the EPO than in the PPO.
- The median deductible was $600 for the EPO and $700 for the PPO.
- The average total cost of EPO coverage per employee was 9% lower than PPO coverage.
Your employer's plans may differ, so compare the numbers in your own benefits guide. Also check the out-of-pocket maximum. For 2026, ACA-compliant plans can't set an in-network out-of-pocket maximum above $10,600 for an individual or $21,200 for a family, according to HealthCare.gov. A PPO's out-of-network care often has a separate, higher limit, or none at all.
A rough rule: if you rarely need care and your doctors are in-network, an EPO's lower premium usually means a lower cost for the year. If you regularly see an out-of-network specialist, a PPO's partial coverage can cost less than paying those bills in full under an EPO.
Referrals and day-to-day use
Both EPO and PPO plans generally let you see a specialist without a referral, which is a key difference from HMO plans. The exception is a gated EPO, which requires a primary care provider referral much like an HMO. Check the plan documents for "referral" before you enroll.
Prior authorization applies to both plan types. Imaging such as MRIs, planned surgeries, and some medications often need insurer approval whether you have an EPO or a PPO.
An EPO has one set of rules and one network, but less room for error: seeing a provider you assumed was in-network can mean paying the full cost. A PPO is more forgiving, but you track separate in-network and out-of-network deductibles. Always confirm a provider in your plan's directory before a visit.
EPO vs PPO and HSAs or FSAs
The EPO or PPO label doesn't decide whether you can contribute to a health savings account (HSA). What matters is whether the plan is a high-deductible health plan (HDHP) under IRS rules. For 2026, an HDHP must have a deductible of at least $1,700 for self-only coverage or $3,400 for family coverage, and an out-of-pocket maximum of no more than $8,500 or $17,000, according to IRS Publication 969. Either plan type can be built as an HDHP. Our PPO vs HDHP guide covers that choice.
A flexible spending account (FSA) depends on your employer, not your plan type, so you can pair one with either an EPO or a PPO. Either account can pay qualified medical expenses such as deductibles, copays, and coinsurance. See HSA vs FSA for how the two accounts differ.
EPO vs PPO: which should you choose?
An EPO may fit if:
- Your doctors and nearest hospitals are in the EPO network
- You rarely need non-emergency care away from home
- Lower monthly premiums matter more to you than out-of-network coverage
A PPO may fit if:
- You want to keep a provider who's outside the EPO network
- You or your family travel often or live in more than one state
- You expect specialized care and want the option to go outside the network
Before you pick during open enrollment, check the provider directory, the drug list, and the cost-sharing details for each specific plan. The label is shorthand; the plan's own rules decide what you pay.
