First pass resolution rate
The percentage of submitted claims that are adjudicated and paid (or fully resolved) on the first submission, without requiring any rework, resubmission, or follow-up. A high first pass resolution rate means your front-end processes are clean: patients are verified, codes are accurate, authorizations are in place, and demographic data is correct before the claim goes out the door.
Why this matters for your clinic
First pass resolution rate measures the quality of your entire billing and clinical documentation workflow in one number. Every claim that fails on first pass costs you administrative time and delays your cash. A 10% improvement in first pass resolution rate on a practice submitting 2,000 claims per month eliminates 200 rework cycles and accelerates cash flow on those claims by days or weeks.
First pass resolution rate and clean claim rate are related but different. Clean claim rate measures whether claims were submitted without technical errors. First pass resolution rate measures whether those claims resulted in payment without further intervention. A claim can be technically clean but still require follow-up if payer processing rules reject it for other reasons. Tracking both gives you a fuller picture of where the process breaks down.
How to calculate
First pass resolution rate = (Claims paid on first submission / Total claims submitted) x 100.
What good looks like
Industry benchmarks for first pass resolution rate in outpatient healthcare typically run 85-92% for well-managed practices. Below 80% signals systematic front-end problems. HFMA and MGMA guidance treats first pass resolution below 75% as requiring immediate process review. Top-performing billing operations target 90%+ consistently. This metric should be tracked monthly and broken down by payer to identify which payers are driving the most rework.
From Sorso
When a practice comes to us with a collections problem, first pass resolution rate is one of the first metrics we calculate from raw 835 data. A low rate almost always points to a specific payer or provider combination rather than a general process failure, which makes the fix targeted and faster.
