What Is a PPO (Preferred Provider Organization)?
PPO plans let you see any doctor or specialist without a referral, both in-network and out-of-network (though out-of-network costs more). PPOs are the most flexible plan type and are a common choice for people with multiple doctors or established specialist care.
Best for: people with established specialist relationships, frequent travelers, or anyone who values the flexibility to see any provider without referrals.
Watch out for: PPOs have higher premiums than HMOs or EPOs. Out-of-network care on a PPO still costs significantly more than in-network care — always try to use in-network providers.
