A preferred provider organization (PPO) is like a club that helps you save money when you go to the doctor. You pay to be part of the club every month, and then you get to go to certain doctors and hospitals that are part of the club. These doctors and hospitals are called "preferred providers."
When you go to one of these preferred providers, you don't have to pay as much money as you would if you went to a doctor who is not in the club. That's because the club has made a special deal with these preferred providers to charge you less money for their services.
But if you want to go to a doctor who is not in the club, you can still go! You just have to pay more money for their services.
Being part of a PPO can be a good idea if you go to the doctor a lot or if you want to have more choices about where you can go for medical care. It can save you money in the long run!
