What CO 246 means

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.

Is It Worth Appealing?

Not a denial. A contracted write-down or patient responsibility. Not money you lost.

Nothing to recover. Confirm it is a reporting code and make sure it is not masking a payable line that was never billed.

  1. 1Step 1: Read the remark code. Find the remark code printed next to CO 246 on the 835 or EOB. It says what the payer wants back.
  2. 2Step 2: Find the cause. Match the denial to one of the cause in Why It Fires above, and fix that one.
  3. 3Step 3: Do this. Nothing to recover. Confirm it is a reporting code and make sure it is not masking a payable line that was never billed.

The common mistake. Do not appeal it. Do check whether the payable service it accompanies actually went out on a claim.

CO 246 description

This code is reported for tracking only and was never going to pay.

This code is reported for tracking only and was never going to pay. 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.

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.

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.
