2025 CPT code 33692
(Active) Effective Date: N/A Revision Date: N/A Surgery - Repair Procedures for Septal Defect Surgical Procedures on the Cardiovascular System Feed
Complete repair of tetralogy of Fallot without pulmonary atresia.
Modifiers may be applicable based on specific circumstances (e.g., 51 for multiple procedures, 58 for staged procedure, etc.).
Surgical correction of tetralogy of Fallot is medically necessary to improve oxygenation, reduce cyanosis, and address hemodynamic compromise. Without repair, the patient may experience progressive heart failure, and reduced quality of life.
The clinical responsibility involves pre-operative assessment, surgical intervention (median sternotomy, CPB, VSD closure with patch graft, infundibular muscle resection), post-operative monitoring, and wound closure.
In simple words: The surgeon repairs a complex heart defect called tetralogy of Fallot by fixing a hole in the heart's wall and removing some extra muscle to improve blood flow. This is done with the help of a heart-lung machine.
This CPT code, 33692, represents the complete surgical repair of tetralogy of Fallot without pulmonary atresia.The procedure involves a median sternotomy to access the heart, placing the patient on cardiopulmonary bypass (CPB). The surgeon closes the ventricular septal defect (VSD), typically using a PTFE patch graft, and addresses right ventricular outflow tract obstruction by removing muscle from the infundibulum. Post-repair, the patient is taken off CPB, and the chest incision is closed.
Example 1: A 2-year-old child presents with cyanosis and shortness of breath, diagnosed with tetralogy of Fallot.The surgeon performs a complete repair using CPT code 33692. , An 8-month-old infant with tetralogy of Fallot undergoes a complete surgical repair. The procedure includes VSD closure and right ventricular outflow tract reconstruction via infundibular resection. , A 5-year-old patient is diagnosed with tetralogy of Fallot and undergoes a complete surgical repair. The surgeon successfully closes the VSD, which was large, and reshapes the outflow tract, relieving right ventricular outflow obstruction. Post-operatively, the child shows significant improvement in oxygen saturation and overall health.
Complete preoperative history and physical examination including echocardiogram, cardiac catheterization results. Intraoperative documentation detailing technique, use of CPB, graft material, size of VSD, and amount of muscle resected.Postoperative records including hemodynamic parameters, length of stay, and complications. Pathology reports if any tissue specimens were obtained.
** This code is for the complete repair; incomplete repairs are coded differently.Pulmonary atresia, if present, necessitates a separate code.
