What is missing
CMS suppresses any plan-county cell with fewer than 11 enrollees. Those enrollees are missing from these counts, so every figure is a floor, not an exact total.
What is counted
Counts cover Medicare Advantage contracts only (Local CCP, Regional CCP, PFFS and MSA). Standalone Part D drug plans, cost plans, HCPP and PACE contracts are excluded.
