Case file: the same claim decided twice

A second Explanation of Benefits arrived for a claim that had already been settled and paid, under the same claim number with a revision suffix.

The reprocessed version assigned $330 more to the patient than the version it replaced. No explanation came with it.

Insurers do reprocess claims, and sometimes the new answer is genuinely correct. A coding correction, a retroactive eligibility change, a lost appeal. But a clawback on a claim you already paid deserves a written reason before you pay the difference.

Check revisions in both directions, because only one of them will be pointed out to you:

• If the revised version lowers your share below what you already paid, that is a refund, and nobody will mention it.
• If it raises your share, that is a clawback, and you should ask why.

What to ask for: the reason for the reprocessing in writing, and note the appeal deadline printed on the revised document before you do anything else.

One practical note. Make sure your own records follow the newest version, and that the provider's balance was recalculated from it rather than from the one it replaced.
