OA-302: Precertification/Authorization Time Limit Expired
COB processing contributed to the authorization expiration. Coordinate authorization timelines across all payers.
What Does OA-302 Mean?
The OA group code indicates this adjustment arose during coordination of benefits processing. The authorization may have expired because COB processing delayed the claim past the authorization window, or the secondary payer has different authorization timeframes.
CARC 302 indicates that the precertification, notification, authorization, or pre-treatment approval associated with the claim has passed its valid time window. Payers require that authorized services be rendered within a specific period, and if the authorization expires before the service date or before claim submission, the payer denies the claim.
This situation typically arises when scheduling delays push a procedure past the authorization window, when a provider fails to request an extension or renewal, or when claim submission is delayed after the authorization period closes. In some cases, data entry errors cause the dates of service to fall outside the authorized range even when the service was rendered on time.
Common Causes
| Cause | Frequency |
|---|---|
| Authorization expired during COB processing Coordination of benefits processing delayed claim adjudication past the authorization valid period | Common |
| Secondary payer authorization timeframe mismatch The secondary payer's authorization requirement has a different validity period than the primary payer | Common |
How to Resolve
- Review COB details to determine which payer's authorization expired
- Contact the applicable payer to request retroactive authorization or extension
- Resubmit with updated authorization information from both primary and secondary payers
Appeal with authorization documentation from both primary and secondary payers showing valid coverage at the time of service.
How to Prevent OA-302
- Track authorization validity across all payers in COB situations
- Coordinate authorization timelines between primary and secondary payers
- Submit claims to both payers promptly to avoid authorization expiration
