What 33762 covers

This operation creates a connection from the descending aorta to a pulmonary artery, directing systemic blood into the pulmonary circulation. It is a palliative congenital heart operation, generally performed by a congenital cardiac surgeon in a hospital operating room when the anatomy and clinical plan call for this specific route of pulmonary blood flow. The Potts-Smith route distinguishes it from shunts originating at the subclavian or ascending aorta, and from a central shunt constructed with a prosthetic graft.

Select the code from the operative report’s documented shunt origin and destination; the report should identify the descending aorta and pulmonary artery and describe the constructed connection. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this anatomy.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Choose 33755 for an ascending-aorta-to-pulmonary-artery route. This code is for the descending aorta.
33764Systemic-pulmonary shunt
33764 describes a central shunt using a prosthetic graft. This code identifies the descending-aorta-to-pulmonary-artery route.

33762 billing questions

How is this distinguished from the other systemic-to-pulmonary shunt codes?

Use the documented arterial origin and route. This code is for a connection from the descending aorta; the related codes cover subclavian-to-pulmonary or ascending-aorta-to-pulmonary routes.

What operative documentation supports this code?

The operative report should identify the descending aorta as the source and the pulmonary artery as the destination, and describe the shunt created.

Is modifier 50 appropriate?

No. Modifier 50 is inappropriate for this shunt’s anatomy.

How are related postoperative visits handled?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

What happens when another procedure is performed in the same session?

Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
