About 33413: Aortic valve replacement with annular enlargement
Reports open aortic valve replacement that includes enlargement of the aortic annulus through a transventricular approach.
This code describes open surgical replacement of the aortic valve combined with enlargement of the aortic annulus using a transventricular approach. A cardiothoracic surgeon may perform this operation when the annulus must be enlarged to accommodate the replacement valve. The procedure involves work beyond replacing the valve alone, including the annular enlargement and ventricular approach.
Report 33413 when the operative report supports both annular enlargement and the transventricular approach; valve replacement by itself does not establish this code. Documentation should identify the replacement, the enlargement, and the approach. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care for 90 days. 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 multiple procedure reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation. Team surgery is not permitted.
