OA-280: Medical Plan Benefits Not Available - Submit to Pharmacy

What Does OA-280 Mean?

OA-280 indicates the medical plan is adjusting the claim to redirect it to the pharmacy benefit, but the adjustment does not fall under standard contractual or patient responsibility categories. This typically appears in coordination of benefits scenarios where the medical plan identifies that the service belongs under a separate pharmacy benefit and adjusts accordingly. The provider should resubmit to the pharmacy plan.

CARC 280 fires when a payer's medical plan receives a claim for a service that belongs under the patient's pharmacy benefit. This is not a traditional denial — it is a redirection. The medical plan is telling you that the service (typically a medication, infusion therapy, or specialty pharmacy item) is covered, but by the pharmacy plan rather than the medical plan.

This code is distinct from CARC 292, which indicates the medical plan has already forwarded the claim to the pharmacy plan. With CARC 280, the medical plan has not forwarded the claim — the provider must obtain the patient's pharmacy plan information and resubmit directly.

The split between medical and pharmacy benefits is increasingly common as payers carve out pharmacy benefits to separate pharmacy benefit managers (PBMs). Self-administered specialty medications, certain injectable drugs, and infusion therapies frequently fall into the pharmacy benefit rather than the medical benefit, and the rules vary by payer and plan design.

How to Resolve

1. Review the adjustment Confirm the adjustment is a redirection to the pharmacy benefit and not a coverage denial.
2. Obtain pharmacy plan details Get the patient's pharmacy plan information and submit the claim to the PBM.
3. Handle if neither plan covers If neither the medical nor pharmacy plan covers the service, contact the payer to determine the appropriate next steps and whether a coverage gap exists.

How to Prevent OA-280

• Verify benefit type (medical vs. pharmacy) before billing
• Collect pharmacy plan information from all patients during intake
• Train billing staff on common medical-pharmacy benefit splits
