How To Use CPT Code 93564

CPT 93564 describes the injection procedure during cardiac catheterization for selective opacification of aortocoronary venous or arterial bypass grafts to one or more coronary arteries and in situ arterial conduits. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 93564?

CPT 93564 can be used to describe the injection procedure during cardiac catheterization for selective opacification of aortocoronary venous or arterial bypass grafts to one or more coronary arteries and in situ arterial conduits. This code is used when the provider passes a catheter into the coronary arteries and injects dye to evaluate heart function in a patient with congenital heart disease.

2. Official Description

The official description of CPT code 93564 is: ‘Injection procedure during cardiac catheterization including imaging supervision, interpretation, and report; for selective opacification of aortocoronary venous or arterial bypass graft(s) to one or more coronary arteries and in situ arterial conduits (eg, internal mammary), whether native or used for bypass to one or more coronary arteries during congenital heart catheterization, when performed (List separately in addition to code for primary procedure)’

3. Procedure

1. The provider introduces a catheter into the coronary arteries, under fluoroscopic guidance.
2. The provider injects dye into one or more arteries to check the blood flow, pressure, and catheter position.
3. The provider catheterizes both native arteries and prior bypass grafts.
4. Multiple injections and views may be performed to obtain comprehensive imaging.
5. The provider supervises the collection of images, interprets the images, and makes a report of the findings.

4. Qualifying circumstances

CPT 93564 is performed during cardiac catheterization in a patient with congenital heart disease. It involves the introduction of a catheter into the coronary arteries, injection of dye into one or more arteries, and evaluation of blood flow, pressure, and catheter position. The procedure includes the catheterization of both native arteries and prior bypass grafts.

5. When to use CPT code 93564

CPT code 93564 should be used when performing the injection procedure during cardiac catheterization for selective opacification of aortocoronary venous or arterial bypass grafts to one or more coronary arteries and in situ arterial conduits. It is important to ensure that the procedure is performed in a patient with congenital heart disease and that the provider is evaluating heart function using dye injection.

6. Documentation requirements

To support a claim for CPT 93564, the provider must document the following information:

• Patient’s diagnosis of congenital heart disease
• Specific details of the injection procedure, including the use of dye and the selective opacification of bypass grafts and arterial conduits
• Date and time of the procedure
• Supervision of image collection and interpretation
• Report of findings

7. Billing guidelines

When billing for CPT 93564, ensure that the procedure is performed during cardiac catheterization for selective opacification of bypass grafts and arterial conduits. It is important to use the appropriate primary procedure code in addition to CPT 93564. Do not report CPT 93564 in conjunction with specific coronary angiography codes for valve repair or annulus reconstruction procedures.

8. Historical information

CPT 93564 was added to the Current Procedural Terminology system on January 1, 2011. There have been no updates to the code since its addition.

9. Examples

1. A provider performs the injection procedure during cardiac catheterization to selectively opacify aortocoronary venous bypass grafts in a patient with congenital heart disease.
2. During a cardiac catheterization, the provider injects dye into arterial bypass grafts and in situ arterial conduits to evaluate blood flow and pressure in a patient with congenital heart disease.
3. A provider performs the injection procedure during cardiac catheterization to selectively opacify aortocoronary arterial bypass grafts and internal mammary arteries in a patient with congenital heart disease.
4. During a congenital heart catheterization, the provider injects dye into aortocoronary venous bypass grafts and native coronary arteries to assess heart function in a patient with congenital heart disease.
5. A provider performs the injection procedure during cardiac catheterization to selectively opacify aortocoronary arterial bypass grafts and free mammary artery grafts in a patient with congenital heart disease.
6. During a cardiac catheterization, the provider injects dye into aortocoronary venous bypass grafts and in situ arterial conduits to evaluate blood flow and pressure in a patient with congenital heart disease.
7. A provider performs the injection procedure during cardiac catheterization to selectively opacify aortocoronary arterial bypass grafts and free radial artery grafts in a patient with congenital heart disease.
