Medicare Advantage Prior Authorization Scorecard

Compare prior authorization denial rates across 37 Medicare Advantage plans. Find which plans deny the most care requests. Plan and enrollment data is drawn from CMS across all 50 states; see our methodology.

What is prior authorization? Medicare Advantage plans often require pre-approval before covering certain treatments, drugs, or procedures. Plans with high denial rates may delay or block necessary care. The appeal overturn rate shows how often denials are reversed on appeal — a high rate suggests many denials were inappropriate.
Data reflects prior authorization requests and denials from CMS OIG and KFF Medicare Advantage analysis. This is for informational purposes only and does not constitute medical advice. Contact CMS or your plan for coverage decisions.
