OA-290: Dental Plan Benefits Not Available - Forwarded to Medical

What Does OA-290 Mean?

When CARC 290 appears with OA, the dental plan is routing the claim without assigning financial responsibility to either the provider or the patient. This is the most common group code pairing because the denial is informational rather than a final determination. The claim is in transit to the medical plan, and the outcome will depend on the medical plan's adjudication. In the OA context, this adjustment typically relates to coordination of benefits between a primary and secondary payer, where the financial responsibility is determined through the COB process.

CARC 290 is a claim routing code rather than a true denial. When this code appears, it means the dental plan received your claim, determined that the service is not covered under the dental benefit, and has forwarded the claim to the patient's medical plan for further consideration. The dental plan is essentially saying the service may qualify for coverage under medical benefits instead.

This code commonly appears for procedures that sit on the boundary between dental and medical coverage. Oral surgery procedures, certain maxillofacial treatments, and medically necessary dental work related to trauma or systemic conditions are frequent triggers. The dental plan recognizes that these services may be within the scope of medical coverage even though they involve the oral cavity.

The important distinction between CARC 290 and CARC 254 is that 290 indicates the claim was actually forwarded to the medical plan, while 254 means the dental plan denied the claim without forwarding it. With CARC 290, the claim should already be in the medical plan's queue, but providers should not assume the forwarding was successful. Active follow-up with the medical plan is essential to avoid the claim falling through the cracks.

How to Resolve

1. Verify claim receipt by medical plan Contact the medical plan within 7 days of receiving the OA-290 remittance to confirm the forwarded claim was received and is in processing.
2. Submit directly if needed If the medical plan has no record of the claim, resubmit directly using the patient's medical plan information with supporting medical necessity documentation.

How to Prevent OA-290

• Determine whether services should be billed to dental or medical plan before initial submission
• Verify coverage under both plans during patient intake to avoid routing delays
