Prior Auth Denial Rates — Week 3 of Public Data
Sources: Becker's Payer Issues, KFF Health News, WCH Insights — March 31–April 8, 2026
The March 31 CMS-0057-F deadline put payer prior auth data online for the first time. Now that payer-specific numbers are being analyzed:
- Centene Medicare Advantage: 93.6% of appealed denials overturned - Oscar ACA plans: 25.3% denial rate - UHC: dropped from 33% to 20% denial rate the year Congress started holding hearings - Overall MA: 80% of appealed denials overturned, per KFF - Physicians now file 39 prior auth requests per week, consuming 13 hours of staff time - Data gap: no service-level breakdown, no denial reasons, no Rx data. KFF called it "offers little insight."
