How To Use CPT Code 33511

CPT 33511 describes the procedure of coronary artery bypass using two coronary venous grafts. This article will cover the official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information and billing examples.

1. What is CPT Code 33511?

CPT 33511 is used to describe the surgical procedure of coronary artery bypass using two coronary venous grafts. This code is used when the provider diverts blood flow from damaged vessels in the heart by grafting two vein segments taken from another location, such as the leg, to restore circulation, improve heart function, and alleviate symptoms like angina.

2. Official Description

The official description of CPT code 33511 is: ‘Coronary artery bypass, vein only; 2 coronary venous grafts.’

3. Procedure

1. The provider harvests two vein segments suitable for coronary artery bypass grafting, typically from the saphenous vein in the leg.
2. A midline sternotomy is performed, which involves making an incision through the breastbone.
3. Aortic and venous cannulas are inserted to establish cardiopulmonary bypass, or machine circulation.
4. A cardioplegia solution is injected to stop the heart for the procedure.
5. The distal ends of the two prepared saphenous veins are attached to appropriate locations on the sides of the diseased target vessels.
6. The proximal ends of the grafts are attached to holes punched into the ascending aorta.
7. The patient is weaned off the bypass pump.
8. The area is irrigated, checked for bleeding, any instruments are removed, and the incision is closed in layers.

4. Qualifying circumstances

Patients who require coronary artery bypass using two coronary venous grafts are eligible for CPT 33511. This procedure is typically performed on individuals with obstructed main arteries of the heart, leading to insufficient blood supply and symptoms like angina. The provider must harvest suitable vein segments, usually from the saphenous vein in the leg, and perform the grafting procedure using a midline sternotomy approach.

5. When to use CPT code 33511

CPT code 33511 should be used when the provider performs coronary artery bypass using two coronary venous grafts. This code accurately represents the specific procedure and distinguishes it from other coronary artery bypass techniques. It is important to ensure that the documentation supports the use of two venous grafts and the specific approach described in the code description.

6. Documentation requirements

To support a claim for CPT 33511, the provider must document the following information:

• Number and type of grafts completed
• Details of the procedure, including the approach used (e.g., midline sternotomy)
• Specific vein segments harvested for grafting
• Date of the procedure
• Any complications or additional procedures performed
• Signature of the provider

7. Billing guidelines

When billing for CPT 33511, ensure that the documentation supports the use of two coronary venous grafts and the specific approach described in the code description. It is important to accurately report the procedure performed to avoid any billing discrepancies. Additionally, consider any specific guidelines or requirements from insurance providers or payers when submitting claims for CPT 33511.

8. Historical information

CPT 33511 was added to the Current Procedural Terminology system on January 1, 1990. The code underwent a change on January 1, 2010, with an updated description. It was also added to the Inpatient Only (IPO) list for Medicare in 2017.

9. Examples

1. A provider performs coronary artery bypass using two coronary venous grafts to restore blood flow in a patient with severe coronary artery disease.
2. During the procedure, the provider grafts two vein segments from the patient’s leg to bypass obstructed coronary arteries and improve heart function.
3. A patient with angina undergoes coronary artery bypass using two coronary venous grafts to alleviate symptoms and improve blood circulation in the heart.
4. The provider performs a midline sternotomy and attaches the prepared saphenous veins to appropriate locations on the diseased target vessels.
5. Using CPT code 33511, the provider accurately bills for the specific procedure performed, ensuring proper reimbursement.
6. A patient with multiple obstructed coronary arteries undergoes coronary artery bypass using two coronary venous grafts to restore blood flow and improve heart function.
7. The provider harvests suitable vein segments from the patient’s leg and performs the grafting procedure using a midline sternotomy approach.
8. By using CPT code 33511, the provider accurately represents the complexity of the procedure and ensures appropriate coding and billing.
9. A patient with severe coronary artery disease undergoes coronary artery bypass using two coronary venous grafts to improve blood flow and alleviate symptoms.
10. The provider carefully selects and prepares the vein segments for grafting, ensuring optimal outcomes for the patient.
