- CO-16: The claim is missing required information or has an error. It is almost always paired with a RARC that names the specific missing field.
- CO-252: The payer needs supporting documentation before it can process the claim.
- MA130: The claim is unprocessable due to incomplete/invalid information, so it was not adjudicated (and has no appeal rights until corrected).
- CO-45: The amount billed is higher than the payer's contracted (allowed) rate. The difference is a contractual write-off, not a patient balance.
- CO-97: This service is bundled into another service that was already paid, so it is not paid separately.
- CO-18: The payer received this exact claim/service already.
