What 33750 covers

The surgeon creates a connection from the subclavian artery to a pulmonary artery to augment blood flow to the lungs. This palliative operation is used for selected congenital heart conditions with inadequate pulmonary blood flow, including some forms of pulmonary atresia or tetralogy of Fallot. It is generally performed by a congenital cardiothoracic surgeon in an operating room, often for an infant or child awaiting further repair or as part of a staged treatment plan.

Report the procedure when the operative record supports the subclavian-to-pulmonary-artery route; the congenital diagnosis alone does not establish this code. Documentation should identify the vessels connected and describe the shunt performed. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
