2025 CPT code 93455
(Valid) Effective Date: N/A Cardiology - Cardiovascular Medicine Feed
Catheter placement in coronary artery(ies) for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation; with catheter placement(s) in bypass graft(s) (internal mammary, free arterial, venous grafts) including intraprocedural injection(s) for bypass graft angiography.
Modifiers 26 (Professional Component) and TC (Technical Component) may be appended to the code when appropriate. Modifier 59 may be necessary to indicate a distinct procedural service.
Medical necessity should be established based on the patient's symptoms, medical history, and other diagnostic tests.The procedure should be performed to diagnose or evaluate a specific cardiac condition impacting the coronary arteries or bypass grafts.
The physician is responsible for inserting and manipulating the catheter, injecting contrast, supervising imaging, interpreting the images, and preparing the report. The physician also performs pre- and post-procedural care.
In simple words: This procedure uses a thin tube (catheter) to examine the blood vessels of your heart and any bypass grafts that may have been placed.Dye is injected to make the blood vessels visible on X-ray images. The doctor then reviews the images to diagnose blockages or other issues.
This code describes a procedure where a catheter is placed in the coronary arteries for angiography, including injections of contrast material to visualize the arteries and bypass grafts. It includes imaging supervision, interpretation, and report generation. This procedure also includes catheter placement(s) in bypass graft(s) (internal mammary, free arterial, venous grafts) with bypass graft angiography.
Example 1: A patient with a history of bypass surgery and angina is referred for evaluation of possible graft blockage. The physician performs cardiac catheterization with angiography of the native coronary arteries and bypass grafts (93455)., A patient presents with unstable angina and a known history of prior coronary artery bypass graft surgery. The patient is taken to the cardiac catheterization lab. Selective catheterization of the coronary arteries and bypass grafts are performed. Coronary angiography is also performed in both areas with imaging supervision and interpretation by the physician. (93455)., A patient with a history of coronary artery bypass grafting presents with symptoms suggesting graft failure. 93455 is performed to assess the patency of the grafts.
Documentation should include a detailed report of the procedure, including the access site, catheters used, areas visualized, findings (including any stenosis or blockages), and any complications. Pre- and post-procedural diagnoses and notes should also be documented. The medical necessity for the procedure should be justified.
** Ensure documentation clearly distinguishes between angiography of native coronary arteries and bypass grafts. Be aware of NCCI edits and code pairing restrictions when billing this code with other procedures. If other diagnostic or therapeutic procedures are performed during the same session, those procedures should be coded separately.
