Medicare Private Fee-for-Service (PFFS) Plan | Medicare GlossaryMedicare Glossary Topic.
A type of Medicare Advantage Plan (Part C) where generally you can go to any doctor or hospital you could go to if you had Original Medicare. The doctor or hospital just needs to agree to treat you. The plan determines how much it will pay the doctors and hospitals, and how much you must pay when you receive any care. A PFFS plan is different than Original Medicare, and you must follow the plan rules carefully when you go to receive health care services. In a PFFS plan, you may pay more or less for Medicare-covered benefits than in Original Medicare.
