What 33852 covers

This service addresses an underdeveloped, narrowed aortic arch, often in a patient with congenital heart disease such as coarctation. A cardiothoracic surgeon performs the open repair without cardiopulmonary bypass. The operative report should establish that the arch hypoplasia was repaired and describe the operative approach and whether bypass was used; the diagnosis alone does not distinguish this code from its bypass counterpart.

Report this code for the repair without bypass, rather than the related arch-repair code for a procedure performed with bypass. CMS assigns a 90-day global period, including the day before surgery 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 the others are subject to a 50% reduction. Modifier 50 is inappropriate for this service. An assistant at surgery may be paid; co-surgeons and team surgery are 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.
