What 33767 covers

A congenital cardiac surgeon creates a pathway from the superior vena cava to the pulmonary arteries so venous blood flows to both lungs. This is commonly a bidirectional Glenn-type operation in staged palliation for selected patients with single-ventricle physiology. It is performed in an operating room, generally by a congenital heart surgery team.

Choose this code when the operative report supports a superior vena cava-to-pulmonary artery shunt serving both lungs; the one-lung version is a different code. Documentation should identify the vessels connected and the extent of the shunt. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.

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.

How to choose

33766Glenn shunt
Use 33766 when the superior vena cava-to-pulmonary artery shunt serves one lung; this code is for a shunt serving both lungs.
33750Systemic-to-pulmonary shunt
33750 describes a shunt from the subclavian artery to the pulmonary artery. This code connects the superior vena cava to the pulmonary arteries.
33764Systemic-pulmonary shunt
33764 describes a central shunt with a prosthetic graft. This code describes a cavopulmonary shunt serving both lungs.

33767 billing questions

How does this differ from 33766?

33767 describes the superior vena cava-to-pulmonary artery shunt serving both lungs. Use 33766 when the documented shunt serves one lung.

Should modifier 50 be appended because both lungs are involved?

No. The bilateral anatomy is built into this code, and CMS identifies modifier 50 as inappropriate.

What operative documentation supports this code?

The operative report should identify the superior vena cava and pulmonary artery connections and show that the shunt serves both lungs.

How are multiple procedures in the same session paid?

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

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team-surgery payment is not permitted.

Does the code include related postoperative care?

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

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.
