2025 CPT code 33410
(Active) Effective Date: N/A Revision Date: N/A Surgery - Surgical Procedures on the Cardiovascular System Surgery Feed
Replacement of the aortic valve using a stentless tissue valve, with cardiopulmonary bypass.
Modifiers such as 51 (multiple procedures), 58 (staged or related procedure), 62 (two surgeons), and 78 (unplanned return to OR) may be applicable depending on the specifics of the case.
Medical necessity is established through clinical documentation demonstrating the presence of symptomatic severe aortic stenosis or regurgitation.This may include symptoms, echocardiographic findings, and cardiac catheterization results showing hemodynamic compromise.The stentless tissue valve is used as a treatment modality to address these symptoms and improve patient outcomes.
The surgeon is responsible for the entire procedure, from incision to closure, including the management of cardiopulmonary bypass.
In simple words: The doctor replaces a faulty heart valve with a special kind of artificial valve that doesn't have a supporting frame (stentless). This major surgery requires a heart-lung machine to keep the blood flowing while the valve is replaced.
This CPT code, 33410, represents the open surgical replacement of the aortic valve with a stentless tissue valve.The procedure involves a median sternotomy, opening the pericardium, establishing cardiopulmonary bypass (CPB), removing the diseased aortic valve, implanting the stentless tissue valve, and closing the incision.Post-operative echocardiogram is typically performed to assess valve function. The use of CPB is inherent to this code.
Example 1: A 75-year-old patient presents with severe aortic stenosis.An echocardiogram confirms the diagnosis.The patient undergoes open-heart surgery with CPB, and the diseased aortic valve is replaced with a stentless tissue valve (33410)., A 62-year-old patient with bicuspid aortic valve and moderate aortic stenosis has progressive symptoms. Surgical valve replacement is indicated.The surgeon performs an open procedure with CPB, replacing the bicuspid valve with a stentless tissue valve (33410)., A patient with a history of previous aortic valve replacement (using a different valve type) requires revision due to valve failure.More than a month has passed since the previous procedure. The surgeon performs a re-do aortic valve replacement with a stentless tissue valve (33410) and adds code 33530 for the reoperation.
Complete surgical report including pre-operative diagnosis, intraoperative findings, type of valve used, and post-operative assessment.Echocardiogram reports before and after surgery. Anesthesia records and cardiopulmonary bypass records. Pathology report if tissue is sent for analysis.
