2025 CPT code 33542

Partial left ventriculectomy (Batista procedure or pacopexy) with mitral valve ring annuloplasty for nonischemic cardiomyopathy.

Follow current CPT coding guidelines for cardiac surgery procedures.

Modifiers may be applicable depending on the circumstances of the procedure (e.g., 51 for multiple procedures, 59 for distinct procedural service, 80 for assistant surgeon).

The procedure is medically necessary when optimal medical management fails to control symptoms of severe heart failure caused by nonischemic dilated cardiomyopathy.The procedure should be considered in patients with significant left ventricular enlargement and associated mitral regurgitation that impact cardiac output and quality of life.

The cardiothoracic surgeon performs the procedure, which requires expertise in cardiac surgery, including ventricular resection and mitral valve repair.

IMPORTANT May be reported with 33999 (Unlisted Cardiac Surgery Procedure) depending on payer preference.33542 and 33999 may be considered investigational or experimental by some payers.

In simple words: The doctor removes a small part of the enlarged left ventricle of the heart and repairs the mitral valve to help the heart pump better. This is done for people with a heart condition not caused by blocked arteries.

This CPT code describes the surgical procedure of partial left ventriculectomy, also known as the Batista procedure or pacopexy.It involves the resection of a viable portion of the enlarged left ventricle to improve cardiac function in patients with nonischemic cardiomyopathy. The procedure often includes a mitral valve ring annuloplasty to correct associated mitral regurgitation.

Example 1: A 65-year-old female patient presents with symptoms of severe heart failure due to nonischemic dilated cardiomyopathy.Cardiac catheterization and echocardiography reveal significant left ventricular enlargement and moderate mitral regurgitation.The cardiothoracic surgeon performs a partial left ventriculectomy (Batista procedure) with a mitral valve annuloplasty to improve left ventricular function and reduce mitral regurgitation., A 70-year-old male patient with a history of nonischemic cardiomyopathy and worsening heart failure undergoes a partial left ventriculectomy (pacopexy).During the procedure, the surgeon resections a portion of the hypertrophied left ventricle and implants a mitral valve ring to correct coexisting mitral regurgitation. The patient’s postoperative course was uneventful., A 58-year-old patient diagnosed with nonischemic cardiomyopathy exhibits severe symptoms of heart failure despite optimal medical management.A left ventriculectomy is performed, addressing ventricular remodeling and mitral valve dysfunction. The patient showed a significant improvement in cardiac function.

* Comprehensive preoperative assessment including history, physical examination, echocardiography, cardiac catheterization, and other relevant imaging studies.* Detailed operative report specifying the extent of left ventriculectomy, techniques used for ventricular reconstruction, mitral valve annuloplasty details, and any other associated procedures.* Intraoperative photographs and videos may be helpful.* Postoperative echocardiography to evaluate left ventricular function and mitral valve competence.

** This procedure may be considered investigational or experimental by some payers; verification of coverage is essential before performing the procedure.
