OA-22: Coordination of Benefits

OA-22 means the payer believes another plan is primary, or the patient's COB information is out of date, so it won't pay until the order is resolved.

Official (X12/WPC): "This care may be covered by another payer per coordination of benefits."

Why payers issue OA-22

  • The patient has a second plan and the primary/secondary order is unclear
  • The member's COB record on file is outdated
  • The primary payer's EOB wasn't attached to the secondary claim
  • Eligibility or coverage dates overlap

Is it recoverable? Usually a sequencing problem, not a coverage problem — once the order and primary EOB are in place, the claim pays.
