OA-22: This care may be covered by another payer per coordination of benefits.
The payer believes there is other insurance that should be billed first, or that coordination of benefits information is missing or incorrect, so it is not processing the claim as primary.
What the group code means
- OA
- Other Adjustment. Used when neither CO nor PR applies.
Why it fires
- The payer's system shows another active policy for this patient that has not been billed or reported
- COB information on file is outdated because the patient has since changed primary coverage
- The claim was submitted without the required COB segment identifying the other payer
Corrective actions, ranked
- 1
Verify the current COB order
Contact the patient or run an eligibility check to confirm which payer is actually primary for this date of service.
- 2
Update COB with the payer
If the payer's records are wrong, such as other coverage having terminated, submit the COB update or attestation the payer requires.
- 3
Bill in the correct order
Submit to the actual primary payer first, then crossover or bill the secondary with the primary's EOB attached.
Is it worth appealing
Appeal or dispute when you have proof the billed payer is actually primary, such as a COB termination letter or patient attestation, and the other coverage does not apply.
