What's the difference between a Medicare Advantage HMO and PPO?

An HMO generally covers only in-network care except for emergencies and often requires referrals to see specialists. A PPO covers out-of-network care too, at higher cost sharing, and usually doesn't require referrals — typically for a higher premium.

Is an HMO or PPO cheaper?

HMOs usually have lower premiums and cost sharing in return for a tighter network. PPOs cost more for the flexibility to use out-of-network providers. Your real cost depends on whether your doctors are in network either way.

HMO vs PPO in Medicare Advantage

Most Medicare Advantage plans are either an HMO or a PPO. The difference comes down to how they handle networks and out-of-network care. Here's the trade-off in plain terms.

The core difference

An HMO covers care from its network and, except for emergencies and urgent care, generally won't pay for out-of-network providers. A PPO also has a network but will cover out-of-network care too, at higher cost sharing. That single difference drives most of the others.

Referrals and gatekeeping

Many HMOs ask you to pick a primary care provider and get a referral before seeing a specialist. Most PPOs don't require referrals. If you value going straight to specialists, that matters; if you prefer coordinated care through one doctor, the HMO model can suit you.

Cost

HMOs often have lower premiums and cost sharing in exchange for the tighter network. PPOs usually cost more for the flexibility, and they carry two out-of-pocket maximums — one for in-network care and a higher combined one that out-of-network care counts toward.

Which suits which situation

An HMO can be a strong fit if your doctors are in the network and you stay local. A PPO is worth the extra cost if you want out-of-network flexibility, travel or live part of the year elsewhere, or want to reach specialists without referrals. Either way, the deciding question is the same: are the doctors and hospitals you actually use in the network?

Before enrolling or making a coverage decision, confirm current details with the plan, Medicare.gov, your State Health Insurance Assistance Program (SHIP), or 1-800-MEDICARE (1-800-633-4227, TTY 1-877-486-2048).
