A PPO plan is designed to give you more flexibility in choosing which health care providers you see. Care is typically more affordable if you stay in-network. But if you have a doctor you prefer to see, it might be easier to visit him or her with a PPO plan.
When it comes to providers, a PPO gives you more options than an HMO: While you still have the option to work with in-network physicians (preferred providers), a PPO also gives you an advantage to visit out-of-network providers and hospitals. If you can afford it, the cost is worth it; PPO plans are the most popular.
