First-pass resolution rate

First-pass resolution rate counts the claims that needed no second touch. A claim counts as resolved on first pass when the payer adjudicates and pays it from the original submission. A claim that is rejected by the clearinghouse, denied by the payer, returned for a correction, or paid only after an appeal does not count, even if the money eventually arrives. Some practices track a narrower cousin, the first-pass acceptance rate, which only asks whether the claim got through the clearinghouse and payer front-end edits. That is useful, but it is not the same thing.

The rate matters because rework is where billing cost and delay live. Every claim that misses on the first pass is touched again, by a person, days or weeks later, and it is at risk of a timely filing or appeal deadline the whole time. A high first-pass rate means eligibility was checked, the authorization was on file, codes and modifiers were right and the claim scrubbed clean before it left. A low rate points to the front end, not to the follow-up team.

The mistake is measuring it on claims paid rather than claims submitted, or measuring it too early. A claim submitted last week has not had time to deny. Measure a fixed cohort of claims after the payers have had time to adjudicate, split it by payer and by rejection or denial reason, and fix the reasons rather than chasing the number.
