With a PPO, you can see any doctor you like, or visit any hospital usually within a preferred network of providers. You always have the option of seeing doctors or visiting hospitals that are “out-of-network,” but you will spend more of your own money on medical expenses. In a PPO, you do not have to choose a Primary Care Physician, and you can usually see any specialist without a referral (although a recommendation is always nice!). The PPO offers choice, flexibility, and more control over your medical life.
