How To Use CPT Code 92921

CPT 92921 describes the procedure of percutaneous transluminal coronary angioplasty for each additional branch of a major coronary artery. This article will cover the official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 92921?

CPT 92921 can be used to describe the percutaneous transluminal coronary angioplasty procedure performed on an additional branch of a major coronary artery. This code is used when the provider inflates a balloon-tipped catheter inside a blocked area of the artery to widen a constricted area and restore blood flow.

2. Official Description

The official description of CPT code 92921 is: ‘Percutaneous transluminal coronary angioplasty; each additional branch of a major coronary artery (List separately in addition to code for primary procedure).’ This code should be used in conjunction with the appropriate primary code for the initial procedure on a single major coronary artery.

3. Procedure

1. After the patient is prepped and anesthetized, the provider repositions the guide catheter and advances a balloon-tipped catheter to the lesion or plaque in an additional branch of a major coronary artery.
2. The provider then inflates the balloon to flatten the plaque against the artery wall, restoring blood flow in the artery.
3. After checking for bleeding, the provider removes any instruments and closes the incision.

4. Qualifying circumstances

CPT 92921 is used when the provider performs percutaneous transluminal coronary angioplasty on an additional branch of a major coronary artery. This procedure is typically performed on patients with blocked or narrowed arteries in the heart. The provider must use a balloon-tipped catheter to widen the constricted area and restore blood flow.

5. When to use CPT code 92921

CPT code 92921 should be used when the provider performs percutaneous transluminal coronary angioplasty on an additional branch of a major coronary artery. This code should be reported in addition to the primary code for the initial procedure on a single major coronary artery.

6. Documentation requirements

To support a claim for CPT 92921, the provider must document the following information:

• Identification of the major coronary artery and the additional branch treated
• Description of the procedure performed, including the use of a balloon-tipped catheter
• Confirmation of restored blood flow in the artery
• Any complications or adverse events encountered during the procedure
• Signature of the provider performing the procedure

7. Billing guidelines

When billing for CPT 92921, ensure that the procedure is performed on an additional branch of a major coronary artery.
