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

What 33416 covers

A cardiac surgeon removes a portion of thickened ventricular septal muscle to widen the left ventricular outflow tract, most often for obstructive hypertrophic cardiomyopathy. The operation is commonly performed through the aortic valve, with or without cardiopulmonary bypass. It is a facility-based major cardiac procedure, not a catheter-based septal reduction treatment.

Report the code when the operative record supports actual ventricular muscle resection; a subaortic membrane excision alone is a different service. Documentation should identify the obstructive condition, the muscle resected, and any separately performed valve procedure. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate for this ventricular procedure. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
