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’s name and Medicare number/Medicare Beneficiary Identifier (MBI) 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.
Make sure the patient information on your claim matches the information on the patient’s Medicare card.
• Enter patient’s name on the claim exactly as indicated on the Medicare card.
• Include spaces and special characters if indicated on Medicare card. Exception: PC-ACE software does not currently accept special characters; enter space instead.
• Enter the patient’s Medicare number/MBI exactly as indicated on the Medicare card. Take a moment to verify that it was keyed correctly.
