HMO or PPO: which Medicare Advantage plan type should I choose?

An HMO covers only its own network of doctors. A PPO also covers doctors outside the network, at a higher cost. Here is how to choose.

A smiling older couple sit across a desk from a doctor in a white coat who is taking notes. — The difference comes down to what happens when you need a doctor outside the network. Decide before you need one.

Key points

An HMO covers only the doctors on its own list, and it usually costs you less each month.
A PPO covers doctors off that list too, and you pay more for it, both monthly and at the visit.
On an HMO, a $2,000 visit to a doctor outside the network is generally yours to pay in full.

An HMO, a Health Maintenance Organization, covers only the doctors and hospitals on its own list. A PPO, a Preferred Provider Organization, also pays part of the bill when you go elsewhere, and costs more each month. If this kind of plan is new to you, start with what Medicare Advantage is.

HMO: lower cost, network only

A network is the list of doctors, clinics and hospitals that have a contract with the plan. On an HMO you stay on that list. Care from a doctor who is not on it is generally not covered at all, apart from emergencies and urgent care.

You pick a primary care doctor, the one who handles your routine care.
You usually need a referral, that doctor's written approval, before a specialist visit is covered.
The premium, the monthly bill for the plan, is typically lower.
Copays, the flat amounts you hand over at each visit, are typically lower too.
This is the most common Advantage plan type, and the most common premium free type.

Here is what network only means in dollars. Say a specialist off the list bills $2,000. The plan pays none of it and you pay all $2,000.

PPO: out of network allowed, at a higher cost

A PPO has a network too, and care inside it costs you the least. A doctor outside the network is still covered. You pay a larger share of that bill and the plan pays the rest.

You can use doctors outside the network and the plan still pays part of the cost.
You usually do not need a referral to see a specialist.
The premium and the copays are typically higher.
There are two out of pocket maximums, the yearly caps on what you can be charged: a lower one for in network care, and a higher one that counts everything together.

You pay for that freedom every month, in the months you use it and the months you do not.

The question that decides it: what happens outside the network

The useful question is how likely you are to need a doctor off the list, and what the bill looks like if that happens. To weigh actual plans, see how to compare Advantage plans.

If your doctors are all local and in network, and you rarely leave the area, an HMO usually gives you more for your money.
If you split the year between two states, travel often, or see a specialist in San Antonio or Houston, a PPO earns its cost.
If you have a condition that could send you to a specialty center out of the area, a PPO is worth a hard look.

On an HMO, a denied out of network claim is a bill for the whole visit, not for an extra amount. Check the network before you make the appointment.

What both types share

Emergency and urgent care are covered anywhere in the United States, in network or not. Go to the nearest emergency room.
Both must cover everything Original Medicare covers.
Both have a yearly out of pocket maximum, a cap on what you can be charged in a year.
Both use prior authorization on many services, meaning the plan approves the care before it pays.

How HMOs and PPOs play out in Hidalgo County

Networks in South Texas are deep, and the major local hospital systems are well represented in them. That is a real reason HMO plans work well for a lot of people here.

The people who should think harder are the ones who travel, who spend part of the year somewhere else, or who cross the state for specialty care. See how Advantage plans handle travel.

Check before you enroll

List your doctors, your specialists and the hospital you would want to use.
Call each billing office and ask whether they take that exact plan for the coming year.
Ask the plan how care outside the network is handled, and what the combined maximum is if it is a PPO.
Ask whether a referral is required, and how long approvals usually take.

Work through that list before you sign anything, using the full guide to checking your doctors. If you would rather do it with someone, call our McAllen office at (956) 687 3334, or enter your ZIP code in the plan pricing box on this page.

Common follow-up questions

Is emergency care covered out of network on an HMO?

Yes. Emergency and urgent care are covered anywhere in the country, on either plan type. Go to the nearest emergency room.

Can I see a specialist without a referral?

On a PPO, usually yes. On an HMO you usually need one first, and skipping it can leave the visit uncovered.

Which type is cheaper?

An HMO almost always costs less each month. Whether it costs less over a full year depends on whether you ever need care outside the network.
