How To Use CPT Code 33692

CPT 33692 describes the complete repair of tetralogy of Fallot without pulmonary atresia. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information and billing examples.

1. What is CPT Code 33692?

CPT 33692 is used to describe the complete repair of tetralogy of Fallot without pulmonary atresia. This code is used when a provider performs a surgical procedure to correct the four heart defects associated with tetralogy of Fallot, including closing a ventricular septal defect and relieving right ventricular outflow tract obstruction.

2. Official Description

The official description of CPT code 33692 is: ‘Complete repair tetralogy of Fallot without pulmonary atresia.’

3. Procedure

1. The provider makes an incision in the chest to access the heart, typically through a median sternotomy.
2. The patient is placed on cardiopulmonary bypass (CPB) to temporarily take over the function of the heart and lungs.
3. The provider approaches the ventricular septal defect either through the atrium or the ventricle and closes the defect using a patch graft, typically made of polytetrafluoroethylene (PTFE).
4. If necessary, the provider removes muscle from the infundibulum to relieve right ventricular outflow tract obstruction.
5. The patient is taken off CPB, and the provider closes the incisions in the heart and checks for bleeding.
6. Any instruments are removed, and the incision in the chest is closed.

4. Qualifying circumstances

CPT 33692 is used for patients with tetralogy of Fallot without pulmonary atresia, a congenital heart defect characterized by a ventricular septal defect, pulmonary stenosis, right ventricular hypertrophy, and an aorta positioned over the ventricular septal defect. The procedure is performed by a provider to correct these defects and improve the patient’s heart function.

5. When to use CPT code 33692

CPT code 33692 should be used when a provider performs a complete repair of tetralogy of Fallot without pulmonary atresia. This code should not be used for repairs involving pulmonary atresia or other associated congenital abnormalities.

6. Documentation requirements

To support a claim for CPT 33692, the provider must document the following information:

• Patient’s diagnosis of tetralogy of Fallot without pulmonary atresia
• Description of the procedure performed, including closure of the ventricular septal defect and relief of right ventricular outflow tract obstruction
• Date of the procedure
• Details of the incision and closure
• Use of cardiopulmonary bypass (CPB)
• Any complications or additional procedures performed
• Signature of the provider

7. Billing guidelines

When billing for CPT 33692, ensure that the procedure performed is a complete repair of tetralogy of Fallot without pulmonary atresia. This code should not be reported with other codes for repairs involving pulmonary atresia or other associated congenital abnormalities. Follow the appropriate coding guidelines and modifiers for accurate billing.

8. Historical information

CPT 33692 was added to the Current Procedural Terminology system on January 1, 1990. The code has not undergone any updates since its addition. However, it is important to stay updated with any changes or revisions to ensure accurate coding and billing.

9. Examples

1. A provider performs a complete repair of tetralogy of Fallot without pulmonary atresia on a pediatric patient, closing the ventricular septal defect and relieving right ventricular outflow tract obstruction.
2. During a surgical procedure, a provider corrects the four heart defects associated with tetralogy of Fallot without pulmonary atresia in an adult patient, improving their heart function.
3. A patient with tetralogy of Fallot without pulmonary atresia undergoes a complete repair procedure, resulting in the closure of the ventricular septal defect and relief of right ventricular outflow tract obstruction.
4. A provider performs a successful surgical repair of tetralogy of Fallot without pulmonary atresia, improving the patient’s heart function and overall health.
5. During a complex procedure, a provider closes the ventricular septal defect and relieves right ventricular outflow tract obstruction in a patient with tetralogy of Fallot without pulmonary atresia.
6. A pediatric patient with tetralogy of Fallot without pulmonary atresia undergoes a complete repair procedure, resulting in improved heart function and quality of life.
7. A provider performs a successful surgical repair of tetralogy of Fallot without pulmonary atresia, correcting the ventricular septal defect and relieving right ventricular outflow tract obstruction.
8. During a procedure, a provider closes the ventricular septal defect and relieves right ventricular outflow tract obstruction in a patient with tetralogy of Fallot without pulmonary atresia, improving their heart function.
9. A patient with tetralogy of Fallot without pulmonary atresia undergoes a complete repair procedure, resulting in the closure of the ventricular septal defect and relief of right ventricular outflow tract obstruction.
10. A provider performs a successful surgical repair of tetralogy of Fallot without pulmonary atresia, improving the patient’s heart function and overall health.
