Return unprocessable claim (RUC) reason code CO 140 FAQ

Q: We received a RUC for claim adjustment reason code (CARC) CO 140. What steps can we take to avoid this RUC code?
Patient/insured health identification number and name do not match
A: You received this RUC, because the patient name and Medicare number on your claim do not match the name and number on the patient’s Medicare card.
Prevent this RUC in the future:
Always request and review your patient’s Medicare card, and make a copy for your file.
If you are a laboratory, radiology department or other entity billing for a diagnostic test sent to you by another provider, request a copy of the patient's Medicare card from the ordering provider.
Verify patient’s Medicare eligibility. Click here for resources to check eligibility.
Make sure patient information on your claim matches the information on the patient’s Medicare card.
Enter patient name on the claim exactly as indicated on the Medicare card.
Include spaces and special characters if indicated on Medicare card. Exception: ABILITY | PC-ACE™ software does not currently accept special characters; enter space instead.
Enter patient Medicare number exactly as indicated on the Medicare card. Take a moment to verify that the number was keyed correctly.
To avoid delay in payment, submit a corrected claim. Claims returned as unprocessable cannot be appealed, as an initial determination was not made. For more information, click here.
