Claim Denial Rate Calculator

Denial Rate (%) = (Denied Claims ÷ Total Claims Submitted) × 100

The HFMA Claim Integrity Task Force publishes two standardized versions of the metric, so benchmark against the same version you calculate:

• By claim volume: total initial denial claims divided by total claims submitted
• By claim dollars: total initial denial claims gross charges divided by total claims submitted gross charges

Some benchmark publishers, including Definitive Healthcare, calculate denial rate on dollar amounts rather than claim counts, so one high-value denial moves the dollar-based rate far more than the volume-based rate. The calculator above uses claim volume, then applies your average claim value to estimate dollars at risk.

A good claim denial rate sits below 5% — the level an MGMA-published analysis identifies as best practice. The industry average runs 5–10% per Definitive Healthcare, and the 2023 MGMA DataDive Practice Operations data set showed a single-specialty aggregate rate of 8% for claims denied on first submission.

Denial rates vary by setting and payer mix: a Premier Inc. survey found nearly 15% of claims submitted to private payers are initially denied, and KFF found HealthCare.gov marketplace insurers denied 20% of in-network claims in 2023. For payer-by-payer and specialty-level detail, see our medical billing denial benchmarks and denial rates by specialty guides.

A denial rate assessment only pays off if it changes what you fix first. Three moves follow directly from the numbers:

1. Fix the front end first. Registration and eligibility problems cause nearly 27% of denials — the largest single driver — and 86% of denials are potentially avoidable, per survey data reported by MGMA. Verifying eligibility before the visit prevents more denial dollars than any back-end workflow.
2. Appeal systematically. A Premier Inc. survey found 54.3% of denials by private payers were ultimately overturned and the claims paid. Reworking a denial costs an average of $25.20 per claim (MGMA); abandoning it forfeits the full claim value.
3. Assign ownership. Appeals stall when nobody owns denial follow-up. Our denial management services run root-cause analysis, appeals, and prevention as a dedicated function; our guide on how to reduce claim denials covers the in-house route.

Note: This calculator provides estimates for educational purposes; its rework estimate of $30 per claim sits between the published $25.20 (MGMA) and $43.84 (Premier Inc.) figures.
