CPT® Code 92979

Add-On Code

Endoluminal imaging of coronary vessel or graft using intravascular ultrasound (IVUS) or optical coherence tomography (OCT) during diagnostic evaluation and/or therapeutic intervention including imaging supervision, interpretation and report; each additional vessel (List separately in addition to code for primary procedure)

Endoluminal imaging of coronary vessels or grafts is a critical procedure that utilizes advanced technologies such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT) to provide detailed visual assessments of the coronary arteries or bypass grafts. This imaging is performed during diagnostic evaluations or therapeutic interventions, allowing healthcare professionals to gain insights into the condition of the blood vessels from within. IVUS employs a miniaturized transducer to create cross-sectional images of the vessel, revealing its structural layers, including the outer adventitia, the media, the intima, and the lumen where blood flows. On the other hand, OCT utilizes near-infrared light to generate high-resolution, three-dimensional images, offering superior detail in identifying smaller dimensions within the lumen and assessing the extent of atherosclerotic plaque buildup or the tissue response to grafting. The procedure involves advancing an IVUS or OCT catheter over a guidewire to the targeted area for evaluation, followed by the physician's interpretation of the images and the generation of a comprehensive report. It is important to note that CPT® Code 92979 is specifically designated for each additional vessel imaged beyond the primary procedure, which is reported using CPT® Code 92978.
