What a PPO is
PPO stands for Preferred Provider Organization. Like an HMO, a PPO has a network of doctors and hospitals where your care costs least. Unlike an HMO, a PPO also covers care outside that network. You pay a larger share out of network, but you are covered, and you generally do not need referrals to see specialists.
The rules that come with it
The trade against an HMO
A PPO usually costs more per month than an HMO in the same county, and copays can be higher. What you are buying is flexibility: the specialist your neighbor recommended, the hospital across the state line, the doctor you see when visiting family. For people who split time between two places, that flexibility can be the whole decision.
Who a PPO suits
People who want Medicare Advantage prices and extras but will not accept a hard network boundary: frequent travelers, people with specialists in another state, and anyone who wants to book specialists without asking permission first.
