CO-225 vs PR-225 vs OA-225: what the prefix means
| Code on your EOB | What the prefix means | Who typically pays |
|---|---|---|
| CO-225 | Contractual obligation — the provider writes the amount off | Usually not the patient |
| PR-225 | Patient responsibility | The patient |
| OA-225 | Other adjustment | Often another payer or plan |
The prefix tells you who is expected to absorb the amount; the number (225) tells you why.
