OA-250: Incorrect Attachment/Documentation Received

What Does OA-250 Mean?

When paired with Group Code OA, the incorrect attachment typically involves a coordination of benefits scenario where the wrong document was sent to the secondary payer. The resolution is the same — locate and submit the correct document.

CARC 250 indicates that the payer received an attachment or supporting document with your claim, but it was the wrong one. The document the payer actually needs has not been provided. This is distinct from CARC 251 (incomplete documentation) — with CARC 250, the problem is not that the document is missing pages or details, but that an entirely incorrect document was submitted.

Common scenarios include sending medical records for the wrong patient, attaching operative notes when office visit notes were requested, submitting an outdated version of a required document, or having an electronic attachment linking error where the wrong file was associated with the claim.

The accompanying RARC codes on the remittance advice are important because they specify what document the payer was expecting. Review these codes carefully before resubmitting to ensure you send the correct attachment the second time.
