What Does OA-285 Mean?

When paired with Group Code OA, CARC 285 typically appears in a secondary payer or coordination of benefits context. The adjustment for appeal procedures not followed is being processed through COB rules. The financial responsibility depends on the specific coordination arrangement between payers.

CARC 285 is a procedural rejection of an appeal — not a decision on the appeal's merits. The payer is saying your appeal was not considered because it did not follow their required submission procedures. The underlying claim denial has not been reviewed on substance.

This is a frustrating but fixable denial. Common procedural failures include submitting the appeal through the wrong channel (mail vs. electronic), using the wrong forms, omitting required supporting documentation, skipping a required level of appeal (e.g., going directly to second-level review without completing first-level), or not addressing the appeal to the correct department. Each payer has specific appeal procedures, and what works for one payer may not work for another.

The critical point is that your appeal window may still be open — CARC 285 does not necessarily mean you have lost the right to appeal. However, the clock is ticking. Review the denial letter immediately, obtain the payer's complete appeal procedure documentation, and resubmit a properly formatted appeal within the remaining timeframe. If the appeal deadline has passed due to the procedural rejection, request an extension citing the circumstances.

How to Resolve

  1. Review the coordination of benefits Examine the OA-285 adjustment and determine how it fits within the primary/secondary payer relationship.
  2. Verify primary payer adjudication Review the primary payer's EOB to understand the basis for the secondary payer's OA adjustment.
  3. Determine appropriate action Based on the COB review, decide whether to accept the adjustment, submit additional documentation, or file an appeal with the secondary payer.
  4. Follow up Monitor the claim and take additional action as needed based on the COB determination.
Do Not Appeal This Code

Appeal Procedures Not Followed grouped under OA is an Other Adjustment that doesn't fall into the standard contractual write-off or patient responsibility categories. Whether action is needed depends on the specific reason — review any accompanying RARC codes and payer guidance to decide whether this is a final adjustment to accept or an issue to resolve through resubmission.
