835 Denial Combination
OA-3
Other Adjustment · Claim-Level Adjustment
Patient ResponsibilityWhat This Combination Means
This combination indicates a copayment amount classified under Other Adjustments rather than standard patient responsibility. The OA group code signals this copayment is being handled in a non-standard manner, typically due to coordination of benefits, workers compensation coverage, or other third-party liability where the copayment responsibility may transfer to another entity or situation beyond the typical patient-owes scenario.
Financial Responsibility
other payer
The copayment is assigned to OA status rather than PR, indicating it may be the responsibility of another payer in a coordination of benefits scenario, workers compensation carrier, or other third-party liability entity rather than the patient directly.

Step-by-Step Resolution
Steps tailored specifically to this OA-3 combination — not generic advice.
- 1
Identify the coordination of benefits or third-party liability situation
Determine whether this is a workers compensation case, auto accident claim, or involves another primary payer that should cover the copayment amount
- 2
Bill the appropriate liable party for the copayment amount
Submit claim to workers compensation carrier, auto insurance, or secondary payer as indicated by the coordination of benefits scenario
- 3
Do not bill patient unless all third-party resources are exhausted
The OA classification indicates this is not standard patient responsibility; only transfer to patient after confirming no other payer is liable
