Executive summary. A reversal is an event that changes the state and economics of an earlier transaction, and that earlier transaction still has to be readable afterwards.

Definition

Claim lineage is the recorded relationship among an original claim, its reversals, corrections, and resubmissions.

Prevent duplicate financial interpretation

Recognize a resubmission as a distinct event with a known relationship to prior attempts. Otherwise a single dispense appears as several expected payments.

Reconciliation rules need to allow for timing, because a reversal and its replacement can land in different payment cycles.

Frequently asked questions

Is a reversal always an error?

No. Reversals arise from corrections, eligibility changes, return-to-stock processes, and payer processes. The reason and the lineage are what matter.
