Billing code 33724: Venous anomaly repairMedicare rate & RVUs

Medicare pays $1,441.92 for 33724 nationally in a facility.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 33724 covers

Code 33724 covers surgical correction of a venous anomaly involving the heart or its major venous connections. A congenital cardiac surgeon performs the repair in a hospital operating room, reconstructing the abnormal pathway so venous blood reaches its intended cardiac destination. The operative report should identify the anomalous vein, where it drained before repair, and how the surgeon redirected or reconstructed the connection.

Select 33724 for the documented venous anomaly repair, rather than for relief of pulmonary venous stenosis, which is described by 33726. Medicare treats this as major surgery: the day-before preoperative visit and 90 days of related postoperative care are included. If other procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50% under the standard multiple-procedure reduction. Modifier 50 is inappropriate for this anatomy. An assistant surgeon may be paid; co-surgeons require supporting documentation. Team surgery is not permitted.
