Fee-for-service
Medicare fee-for-service is Original Medicare paying a covered claim as it is submitted. A Medicare Administrative Contractor processes the claim. Medicare Advantage is different: the plan receives a monthly payment and pays its own claims. Star Ratings score those plans, not fee-for-service. The ratings lookup is at /star-ratings-2027.
