First decide what counts as clean
Teams often use “clean claim” to mean three different things: accepted by the clearinghouse, accepted into the payer’s adjudication system, or paid without manual intervention. Those are not interchangeable. A claim can clear front-end edits and still deny for a missing tooth clause, attachment, or enrolment problem.
Our useful definition starts at first submission and ends at adjudication. The numerator is claims paid or assigned patient responsibility without a correction, rejection, or avoidable documentation request. The denominator includes every claim first submitted in the same period, including claims that are still unresolved at the reporting cut-off.
Do not let resubmissions disappear
A common reporting error counts the corrected claim as a new clean submission. The original failure vanishes and the metric improves precisely because the team did more work. Keep the original claim identity and attach every correction to it.
We also separate payer-caused reprocessing from practice-caused correction. Both consume time, but only one points to an upstream intake, coding, attachment, or credentialing fix.
Use cohorts, not a moving pile
Measure claims by submission week or month and allow a stated maturity window. Comparing yesterday’s immature claims with last month’s fully adjudicated claims makes the current period look artificially clean.
The metric matters only when it opens a worklist: the five most frequent preventable causes, the dollars delayed, the location or provider affected, and the earliest workflow step that can prevent the repeat.
