Charge is above the contracted rate. The difference is written off.
CO: Contractual obligation. The provider absorbs it and cannot bill the patient.
So the balance cannot move to the patient. Either the appeal recovers it or the practice absorbs it. That makes the appeal decision the whole decision on this line.
Not a denial. A contracted write-down or patient responsibility. Not money you lost.
In the order we see it.
The charge exceeds the contracted rate. This is the write-down you agreed to.
Contractual adjustment. Only worth review if the fee schedule loaded wrong.
The documentation, not the argument.
The common mistake. Do not appeal a correct contractual adjustment. Do check that the fee schedule loaded correctly, because a bad load shows up here first.
Where this comes from. This is our own reading of the code, not the payer's and not a copy of the standards text. We classify it from how these denials actually resolve. Where we are unsure, we say so rather than guessing.

This is our plain-English wording, not the official X12 text. X12 asserts copyright over the published descriptions, so we write our own and say what it means for the money rather than restating the code.
The adjustment code says the claim was reduced. The remark code printed next to it says why, and it is the one that tells you what to send back.
| Remark | What it means |
|---|---|
| N381 | The payer is pointing at your contract rather than naming the rule it applied. |
