HMO vs. PPO: What Is the Difference?

HMO vs. PPO: Side-by-Side Comparison

HMOs suit people with a trusted primary care doctor whose specialists are already in-network. PPOs suit people with chronic conditions requiring multiple specialists, frequent travelers, or anyone whose preferred providers are outside an HMO's network.

Do I need a referral with an HMO?

Yes. Your primary care physician must refer you to a specialist before the visit is covered. Emergency care is the exception: go directly to an ER. PPOs have no referral requirement.

Can I see an out-of-network doctor with an HMO?

No, except for medical emergencies. Routine out-of-network visits are your full cost. PPOs cover out-of-network care at a higher coinsurance rate than in-network.

When does an HMO make more sense?

Choose an HMO if you are generally healthy, want the lowest premium, and your doctors are already in-network. HMOs also pair well with CSR Silver plans for households at 100% to 250% of the federal poverty level.

What are EPO and POS plans compared to HMO and PPO?

An EPO has no referrals required (like PPO) but no out-of-network coverage (like HMO). A POS requires a PCP referral (like HMO) but allows out-of-network care (like PPO). Both sit between HMO and PPO on the flexibility spectrum.
