What 33602 covers

A congenital cardiac surgeon uses this procedure to surgically seal the pulmonary valve opening during open heart surgery, typically with cardiopulmonary bypass. It is selected when the operative plan calls for closure of the pulmonary valve orifice, rather than repair or replacement of the valve. The setting is generally a hospital operating room for congenital heart reconstruction; the code identifies the valve opening being closed, not a particular age group or single diagnosis.

Report the code when the operative note documents pulmonary valve orifice closure and distinguishes it from other repairs performed during the same operation. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during the following 90 days. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted. Modifier 50 is inappropriate for this single valve-orifice procedure.

How to choose

33600Valve closure
Both codes describe valve-orifice closure during congenital cardiac surgery. Choose 33602 for the pulmonary valve and 33600 for the aortic valve.
33475Pulmonary valve replacement
33602 seals the pulmonary valve opening; 33475 replaces the pulmonary valve. The operative objective, not simply the valve involved, determines the code.
33620Pulmonary artery banding
33620 places bands on the right and left pulmonary arteries; it does not close the pulmonary valve orifice.

33602 billing questions

How is 33602 different from 33600?

33602 is for closure of the pulmonary valve orifice; 33600 is for closure of the aortic valve orifice. The operative report should identify which valve opening was sealed.

Is this code for pulmonary valve repair or replacement?

No. It represents surgical closure of the pulmonary valve opening. Valve reconstruction or replacement describes a different operative service.

Can modifier 50 be reported?

No. Modifier 50 is inappropriate for this single pulmonary valve-orifice procedure.

What documentation supports reporting 33602?

Document the pulmonary valve orifice closure, the operative approach, and the other congenital repairs performed in the session. The record should distinguish closure from valve repair or replacement.

How does the 90-day global period affect postoperative care?

The day-before preoperative visit and related postoperative care during the 90 days after surgery are included in the global period.

Can an assistant or co-surgeon be reported?

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

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.
