Hospitals Lost $48 Billion in Revenue to Payer Denials in 2025
A benchmarking analysis of more than 2,300 hospitals and 350,000 physicians’ revenue cycle data found that providers improved payment speed in 2025 — average days to insurance payment fell from 57.4 to 55.2 — but revenue leakage grew by roughly 25%, with analyzed hospitals collectively missing $48.4 billion. The culprit is rising payer denial rates, particularly clinical denials tied to prior authorization and medical necessity determinations. Average clinical initial denial rates rose from 2.4% to 2.6%, while providers’ ability to overturn those denials declined slightly. Inpatient claims faced the sharpest pressure, with clinical denial rates climbing more than 12%. Insured patients were also responsible for a larger share of bills in 2025 — 7.3%, up from 6.8% — and paid a smaller portion of what they owed.
Faster payment timelines are masking a deeper revenue erosion problem. Operators without strong denial prevention, clinical documentation, and appeals processes are quietly leaking tens of millions. With Medicaid disenrollment pressures accelerating in 2026, the window to fix this is narrowing.
