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 do not match the name and number on the patient’s Medicare card. To avoid this RUC in the future:
Review and make a copy of Medicare card for the patient’s file.
If you are a laboratory, radiology department or other entity where the patient was referred and/or the patient’s diagnostic test was sent, obtain a copy of the patient's Medicare card from the referring provider. Ensure your claim is submitted with the correct information as indicated on patient’s Medicare card.
Verify patient’s Medicare eligibility. Click here for resources to check eligibility.
Enter patient name on claim exactly as indicated on 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 Medicare card. Take a moment to verify number was keyed correctly.
To avoid delay in payment, submit a corrected claim. Claims that are returned as unprocessable cannot be appealed, as an initial determination was not made. For more information, click here.
