HMO, PPO, EPO, and HDHP Plans Compared

Health plans are often labeled with a string of letters. Those letters describe how the plan’s network works: which doctors you can see, whether you need referrals, and whether out-of-network care is covered. A high-deductible health plan, or HDHP, is a little different because it describes the cost structure rather than the network. Here is how they compare.

Quick comparison

Plan type	Network flexibility	Referrals for specialists	Out-of-network coverage	Typical cost pattern
HMO	Stay in network	Usually required	Generally none except emergencies	Lower premiums, predictable copays
PPO	Widest	Usually not required	Yes, at higher cost	Higher premiums
EPO	Stay in network	Often not required	Generally none except emergencies	Often between HMO and PPO
POS	Mix of HMO and PPO	Usually required	Yes, at higher cost	Varies
HDHP	Can be HMO, PPO, or EPO style	Depends on network type	Depends on network type	Lower premiums, higher deductible

These are general patterns. Individual plans vary by insurer, employer, and state, so check the plan’s own documents.

HMO: Health Maintenance Organization

An HMO usually asks you to choose a primary care provider who coordinates your care. If you need a specialist, your primary care provider typically refers you. Care outside the network is generally not covered except for emergencies.

Might suit you if: you are comfortable using a set network, want lower premiums, and like having one doctor coordinate things.

Watch for: the size of the network in your area and whether the specialists you need are included.

PPO: Preferred Provider Organization

A PPO gives you the most freedom. You can usually see specialists without a referral, and the plan covers some out-of-network care, though at a higher share of cost to you. That flexibility tends to come with higher premiums.

Might suit you if: you want to keep doctors who are not in every network, travel often, or prefer to self-refer to specialists.

Watch for: out-of-network costs can add up, and out-of-network providers may bill you for amounts above what the plan allows.

EPO: Exclusive Provider Organization

An EPO is like a hybrid. Like an HMO, it usually does not cover out-of-network care except emergencies. Like a PPO, it often lets you see in-network specialists without a referral.

Might suit you if: your preferred doctors are all in network and you want to skip referrals.

Watch for: accidentally seeing a provider who is out of network, since that care may not be covered at all.

POS: Point of Service

A POS plan blends HMO and PPO features. You typically pick a primary care provider and need referrals, but you may have some out-of-network coverage at a higher cost.

HDHP: High-Deductible Health Plan

An HDHP has a higher deductible and usually a lower premium. The network itself can follow any of the models above. What sets many HDHPs apart is eligibility for a health savings account (HSA), which lets you set aside money for medical costs with tax advantages, subject to federal rules and annual contribution limits.

Might suit you if: you are generally healthy, want lower monthly costs, and can afford to cover a larger deductible if something happens.

Watch for: you pay more up front before the plan shares costs. Preventive care is typically covered before the deductible, but most other care is not.

How to decide

Ask yourself four questions:

1. Are my doctors in the network? This matters more than the letters on the plan.
2. Do I mind referrals? If not, HMO and POS plans may work well.
3. How much care do I usually use? Frequent care often favors plans with lower deductibles and copays; infrequent care may favor lower premiums.
4. Could I handle the full deductible or out-of-pocket maximum? Your comfort with that number is a key part of the choice.

A final tip

Compare plans on total yearly cost, not premium alone. Add up premiums plus your realistic out-of-pocket spending for a low-use year and a high-use year. The plan that looks least expensive on the monthly bill is not always the least expensive over twelve months.
