Cardiac caths

I found the answer to the question within the articles on this site.
thank you

re: Cardiac caths

These are procedure descriptions:

93452
The physician threads a catheter to the heart, most frequently through an introducing sheath placed percutaneously into the femoral, brachial, or axillary artery using retrograde technique. Using this technique, the catheter passes through the aortic valve into the left ventricle. Intracardiac and intravascular pressures are recorded. Left ventricular injections may be performed for left ventriculography; the physician injects dye through a previously placed catheter threaded through a central line into the left ventricle or atrium to evaluate function with fluoroscopy. Imaging supervision and interpretation, when performed, are included in this code, as is any required repositioning of catheters.

93453
This procedure is performed to evaluate both right and left heart function. To accomplish right heart catheterization, the physician threads a catheter through an introducing sheath placed percutaneously into the femoral, subclavian, internal jugular, or antecubital vein. The catheter is threaded into the right atrium, through the tricuspid valve into the right ventricle, and across the pulmonary valve into the pulmonary arteries. Left heart catheterization is also performed, in this case using retrograde technique. The catheter is inserted through an introducing sheath placed percutaneously into the femoral, brachial, or axillary artery. The catheter is passed through the aortic valve into the left ventricle. Intracardiac and intravascular pressures are recorded. Left ventricular injections may be performed for left ventriculography; the physician injects dye through a previously placed catheter threaded through a central line into the left ventricle or atrium to evaluate function with fluoroscopy. Imaging supervision and interpretation, when performed, are included in this code, as is any required repositioning of catheters.

93458-93459 ( 93458, 93459)
The physician places a catheter into one or more coronary arteries for coronary angiography. The physician threads a catheter to the heart, most frequently through an introducing sheath placed percutaneously into the femoral, brachial, or axillary artery using retrograde technique. The catheter passes through the aortic valve into the left ventricle. Intracardiac and intravascular pressures are recorded. Left ventricular injections may be performed for left ventriculography; the physician injects dye through a previously placed catheter threaded through a central line into the left ventricle or atrium to evaluate function with fluoroscopy. Code 93459 includes catheter placement in one or more bypass grafts with bypass graft angiography. The physician removes the catheter and sheath from the femoral artery. Pressure is placed on the wound for 20 to 30 minutes to stem bleeding. These codes include imaging supervision and interpretation, as well as any required repositioning of catheters.

93460-93461 ( 93460, 93461)
The physician places a catheter in one or more coronary arteries for coronary angiography. In 93460, right and left heart function is evaluated. To accomplish right heart catheterization, the physician threads a catheter through an introducing sheath placed percutaneously into the femoral, subclavian, internal jugular, or antecubital vein. The catheter is threaded into the right atrium, through the tricuspid valve into the right ventricle, and across the pulmonary valve into the pulmonary arteries. Left heart catheterization is also performed, in this case using retrograde technique. The catheter is inserted through an introducing sheath placed percutaneously into the femoral, brachial, or axillary artery. The catheter is passed through the aortic valve into the left ventricle. Intracardiac and intravascular pressures are recorded. Left ventricular injections may be performed for left ventriculography; the physician injects dye through a previously placed catheter threaded through a central line into the left ventricle or atrium to evaluate function with fluoroscopy. Code 93461 includes catheter placement in one or more bypass grafts for angiography. The physician removes the catheter and sheath from the femoral artery. Pressure is placed on the wound for 20 to 30 minutes to stem bleeding. These codes include imaging supervision and interpretation, as well as any required repositioning of catheters.

Hope this helps
