HMO vs. PPO vs. EPO: Which Health Plan Type Should You Choose?
Network type decides which doctors you can see. Compare HMO, PPO, EPO, and POS plans on referrals, out-of-network coverage, and premium.
HMO, PPO, EPO, and POS are network types that decide which doctors you can see and how you see them. The network type affects your premium, your referrals, and your out-of-network coverage. The metal level shows how a plan splits costs; the network type shows where you can get care. This guide compares the four types and explains which one fits your situation.
What is the difference between HMO, PPO, EPO, and POS plans?
HMO, PPO, EPO, and POS plans differ on out-of-network coverage, referrals, and price. The table compares the four network types.
| Plan type | Out-of-network coverage | Specialist referral | Primary care doctor required | Typical premium |
|---|---|---|---|---|
| HMO | Emergencies only | Usually yes | Usually yes | Lower |
| EPO | Emergencies only | Usually no | Usually no | Lower to middle |
| POS | Some, at higher cost | Usually yes | Usually yes | Middle |
| PPO | Yes, at higher cost | No | No | Higher |
Plan rules vary by insurer. Always read the plan's Summary of Benefits and Coverage before you enroll.
What is an HMO plan?
An HMO (health maintenance organization) plan covers care from doctors inside its network. You usually pick a primary care doctor who coordinates your care. HMO plans usually require a referral before you see a specialist. HMO plans cover out-of-network care only in emergencies. In return, HMO plans often carry lower premiums and lower out-of-pocket costs.
What is a PPO plan?
A PPO (preferred provider organization) plan gives you the most freedom to choose doctors. You can see specialists without a referral. PPO plans also pay for some out-of-network care, at a higher share of the cost to you. That flexibility usually comes with a higher premium. In many areas, PPO plans are less common on the individual market than HMO and EPO plans.
What is an EPO plan?
An EPO (exclusive provider organization) plan mixes features of HMO and PPO plans. You usually don't need a referral to see a specialist. An EPO plan covers out-of-network care only in emergencies, like an HMO. EPO plans often cost less than PPO plans and offer more freedom than HMO plans. EPO plans suit people whose doctors all sit in one network.
What is a POS plan?
A POS (point of service) plan works like an HMO with some out-of-network coverage. You usually choose a primary care doctor and need referrals for specialists. A POS plan pays part of out-of-network care, at a higher cost to you. POS plans appear less often on the individual market than the other three types.
Which plan type should you choose?
Your doctors and your travel habits matter more than the plan label. Use these decision rules:
- All your doctors in one network: an HMO or EPO usually costs less
- Several specialists: an EPO or PPO avoids referral steps
- Out-of-network care wanted: choose a PPO or POS
- Part of the year in another state: check out-of-area coverage first
- Lowest premium wanted: compare HMO plans first
How do you check whether your doctor is in network?
Checking your doctor's network status takes three steps. Networks change every year, so check again at each renewal.
- Search the insurer's current provider directory by the exact plan name
- Call the doctor's office and ask whether it accepts that specific plan for 2027
- Confirm your hospital and lab are in the same network
The same insurer can offer several networks. A doctor in one network may be out of network on another plan from the same insurer.
Do private plans use networks too?
Private plans outside the marketplace use provider networks too, and network rules vary by plan. Private plans ask health questions, so eligibility depends on your answers. Depending on your health and situation, a private plan may cost less. If a private plan isn't the right fit, ACA plans can't turn you down because of a pre-existing condition.
