First Pass Rate

First pass rate is the percentage of claims that are accepted and paid by the payer on first submission, without rejections, denials, or additional information requests. It is the operational counterpart to clean claim rate — closely related but not identical. Clean claim rate measures whether a claim passed scrubbing edits at submission; first pass rate measures whether it actually made it through payer adjudication and produced a payment. Industry average first pass rates hover at 85-90%. Top-quartile practices and specialized billing teams hit 96%+. Each percentage point of first pass rate is meaningful dollars: on a practice billing $1.5M annually, a 5-point improvement in first pass rate (from 88% to 93%) recovers $25-50K in margin per year through reduced rework labor and faster cash flow. The three foundations of high first pass rates are real-time eligibility verification 48-72 hours before service, payer-specific clean-claim scrubbing rules, and AAPC-certified coding with NCCI edit checks before submission. Practices that hit 96%+ rates do all three systematically. Tracking first pass rate weekly, broken out by payer, surfaces the worst-performing payer relationships and the upstream prevention failures driving them — typically one or two payers contribute disproportionately to the rejection/denial volume.
