 For each person who chooses to enroll in a Part C Medicare Advantage or other Part C plan, Medicare pays the health plan sponsor a set amount every month ("capitation").The capitated fee associated with a Medicare Advantage and other Part C plan is specific to each county in the United States and is primarily driven by a government-administered benchmark/framework/competitive-bidding process that uses that county's average per-beneficiary FFS costs from a previous year as a starting point to determine the benchmark.The fee is then adjusted up or down based on the beneficiary's personal health condition; the intent of this adjustment is that the payments be spending neutral (lower for relatively healthy plan members and higher for those who are not so healthy).
