About 33476: Right ventricular chamber reconstruction
Reports surgical reconstruction of the right ventricular chamber, with or without a patch, when operative treatment requires reshaping or rebuilding that chamber.
This code describes surgical reconstruction of the right ventricular chamber, with or without patch material. A cardiothoracic surgeon performs the operation in a hospital operating room to address a structural problem requiring chamber reconstruction. The operative report should identify the right ventricle and describe the reconstruction performed; a procedure limited to a valve, septum, or other cardiac structure is not this service.
Report the code for the right-sided chamber reconstruction rather than a left ventricular procedure or a code describing work confined to another structure. Documentation should support the indication, anatomy treated, and operative technique. Medicare 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% multiple-procedure reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation. Team surgery is not permitted, and modifier 50 is inappropriate.

33476 billing questions
How is this code distinguished from 33478?
This code is for reconstruction of the right ventricular chamber. Code 33478 describes the corresponding left ventricular chamber procedure.
Can this be reported with a cardiac valve procedure?
It may be reported with another procedure when the surgeon performs distinct, separately documented work on the ventricular chamber and the valve in the same session. The multiple-procedure reduction applies when procedures are performed together.
What documentation supports reporting this service?
The operative report should identify the right ventricle, explain the structural problem, and describe the chamber reconstruction, including any patch work.
Can modifier 50 be used?
No. The anatomy and service are not bilateral for Medicare payment purposes, so modifier 50 is inappropriate.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
