A patient underwent coronary artery bypass graft with three venous vessels as a repeat CABG. What code(s) should be reported?

The correct choice for reporting the procedure is based on the established coding guidelines for coronary artery bypass graft (CABG) surgeries, specifically noting that this was a repeat CABG using three venous grafts.

The codes 33512 and 33530 are specifically designed for CABG procedures. Code 33512 denotes a coronary artery bypass graft, using a venous graft, and is appropriate for a repeat surgery. It is used when there is one additional graft in addition to the primary graft being performed, which indicates that this is not the first time the patient has undergone this surgery. Code 33530 is used for additional bypass grafting, representing the use of multiple grafts.

In this case, having used three venous grafts during a repeat CABG, both codes are necessary to accurately capture the complete scope of the surgical intervention performed. This aligns with coding standards for accurately documenting the complexity and type of surgical work performed, ensuring proper representation for billing and medical records.

The other options provided do not relate directly to the specific procedure of CABG with venous grafts, making them unsuitable choices in this context.
