Congenital cardiac surgery

About 33615: Modified Fontan circulation repair

Reports open surgical modification of Fontan circulation for congenital single-ventricle physiology, connecting systemic venous return with pulmonary blood flow.

A modified Fontan operation redirects systemic venous blood to the pulmonary arteries in a patient with single-ventricle physiology, so blood reaches the lungs without being pumped through a functional right ventricle. A congenital cardiac surgeon performs the reconstruction in an operating room, commonly using an intra-atrial pathway or an extracardiac conduit as part of the Fontan circulation.

Report 33615 when the operation performed matches this modified Fontan repair, rather than selecting it solely because the patient has single-ventricle anatomy. The operative report should identify the congenital anatomy and describe the venous-to-pulmonary connection and reconstruction performed. This major surgery includes 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.

33615 compared with similar codes

Office rates for Connecticut, from the same CMS release.

33617

Single-ventricle repair

With cardiopulmonary bypass

No office rate

Both are single-ventricle repair procedures. Use 33615 only when the documented operation matches its CPT-defined Fontan variant; compare the full descriptors for the specific operative distinction.

33619

Single-ventricle repair

With aortic arch repair

No office rate

This is another single-ventricle repair code. The operative report, not the diagnosis alone, determines which CPT-defined variant applies.

33622

Congenital heart surgery

Complex reoperation

No office rate

This code addresses redo surgery for a complex congenital cardiac anomaly. Code 33615 describes a modified Fontan repair, not redo status by itself.

33615 billing questions

How do I distinguish 33615 from 33617 or 33619?

All are single-ventricle repair codes. Select the code whose CPT-defined operative variant matches the procedure documented; do not choose among them based only on the Fontan diagnosis.

What documentation supports reporting 33615?

The operative report should establish the single-ventricle anatomy and describe the modified Fontan reconstruction, including the systemic venous route to the pulmonary arteries.

Are related postoperative visits included?

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

How are other procedures in the same session paid?

Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.

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.
