CO-150 vs PR-150 vs OA-150: what the prefix means
| Code on your EOB | What the prefix means | Who typically pays |
|---|---|---|
| CO-150 | Contractual obligation — the provider writes the amount off | Usually not the patient |
| PR-150 | Patient responsibility | The patient |
| OA-150 | Other adjustment | Often another payer or plan |
The prefix tells you who is expected to absorb the amount; the number (150) tells you why.
