A clean claim is a claim the payer accepts and adjudicates on first submission, with no errors, no missing information and no request for more documentation. HFMA measures the same idea before submission, counting claims that “pass edits requiring no manual intervention.” Clean claim rate is the share of claims that get through untouched.
Clean claim rate = (claims paid on first submission ÷ total claims submitted) × 100
Count a claim in the numerator only if the payer adjudicated it the first time, with no correction, resubmission, attachment request or phone call. Every claim submitted in the period goes in the denominator.
Illustrative example. A practice submits 1,000 claims in March. 870 are paid on first pass with no one touching them again, so the clean claim rate is 870 ÷ 1,000 × 100 = 87%.
Practices most often get the numerator wrong in two ways:
HFMA’s version, MAP Key CL-1, divides claims that pass edits with no manual intervention by claims accepted into the claims processing tool. That is a scrubber measure taken before submission. Pick one definition and report it the same way every month.
The target most often quoted is 95% to 98%, repeated widely by billing vendors and trade articles. We could not find that figure in HFMA’s or MGMA’s own published material, so treat it as a common goal and not a measured norm.
Measured medians sit lower. MGMA DataDive’s 2024 Practice Operations survey puts the median family medicine practice at an 85.0% clean claim rate, based on 2023 data, as presented by Forvis Mazars at the Kansas MGMA conference in April 2026.
A rate below 90% means at least one claim in ten is worked twice before it pays. That rework usually traces to the front desk: eligibility, registration and authorization. Optum’s 2024 Revenue Cycle Denials Index found an average denial rate of 12% across hospital claims in 2023.
Clean claim rate sits upstream of every other revenue cycle number. Denial rate, days in A/R and net collection rate all move after claims have already failed, while clean claim rate shows the failure at the moment it happens.
Each dirty claim costs three ways. Someone has to work it, the cash arrives a cycle or two later, and some share of it ages past the payer’s deadline before anyone finishes. Track the rate weekly and a drop of a few points shows up before it reaches the bank account.
It also grades the billing operation itself. Comparing clean claim rate by biller, payer and location shows where training or process is failing far faster than a month-end collections report.
The five causes below are ordered by their share of denials in Optum’s 2024 Revenue Cycle Denials Index. That index measures hospital claims, so a physician practice’s mix will differ, but the order is a reasonable place to start.
Each fix is a front-desk or pre-submission step, which is why the work belongs before the claim leaves the building. For groups running these checks across several sites, see how we handle billing for group practices, or use the RCM Intelligence framework to plan the changes in order.
At Vally Medical Group we run four locations, and a single group-wide clean claim rate was the number that told us the least. A 92% average can be one site at 96% and another at 84%, with the strong site pulling the weak one out of view. Those figures are illustrative, but the pattern is the one we saw.
The fix is to report the rate by location and by payer every week, next to the aging report for that site. Our guide to reading an aging report by location shows the same problem from the A/R side.
What is a clean claim in medical billing?
A clean claim is a claim the payer accepts and adjudicates on first submission, with no errors, no missing information and no request for more documentation. HFMA measures the same idea before submission as claims that pass edits with no manual intervention.
How do you calculate clean claim rate?
Divide the claims paid on first submission by the total claims submitted, then multiply by 100. A practice that submits 1,000 claims and has 870 paid with no rework has an 87% clean claim rate. Claims accepted by the clearinghouse or paid after a correction do not count as clean.
What is a good clean claim rate?
The commonly quoted target is 95% to 98%, though we could not find it in HFMA or MGMA published material. MGMA DataDive puts the median family medicine practice at 85.0%. Below 90% means at least one claim in ten is worked twice.
How can a practice improve its clean claim rate?
Start with the largest denial causes: eligibility and registration, missing claim data, authorization, documentation requests and non-covered services. Each has a check that can run before the claim is submitted. Track the rate weekly by location and payer to see which fix is working.
