Federal PA reporting mandates release insurer denial rates, UHC above 18%
Publicly reported prior authorization data, mandated by CMS regulations that took effect this year, now provides concrete denial rates by payer. KFF analysis of the first reporting cycle shows UnitedHealthcare posted a denial rate above 18% for medical services, with other major national insurers ranging between 12% and 18%. This is the first time practices can compare payer-specific PA denial performance using standardized federal data, moving beyond anecdote. The data exposes the operational burden: for every 100 prior auth requests submitted to UHC, at least 18 are initially denied, triggering appeal work. Use this baseline to benchmark your practice's own denial rates against these national figures and to inform contract negotiations.
