CO-24 vs PR-24 vs OA-24: what the prefix means
| Code on your EOB | What the prefix means | Who typically pays |
|---|---|---|
| CO-24 | Contractual obligation — the provider writes the amount off | Usually not the patient |
| PR-24 | Patient responsibility | The patient |
| OA-24 | Other adjustment | Often another payer or plan |
The prefix tells you who is expected to absorb the amount; the number (24) tells you why.
