Common Language Description

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.

1. Indications

The endoluminal imaging of coronary vessels or grafts using intravascular ultrasound (IVUS) or optical coherence tomography (OCT) is indicated for various clinical scenarios, particularly during diagnostic evaluations and therapeutic interventions. The following conditions may warrant the use of this imaging technique:

  • Assessment of Coronary Artery Disease This procedure is performed to evaluate the presence and severity of coronary artery disease, particularly in cases where traditional imaging methods may not provide sufficient detail.
  • Evaluation of Bypass Grafts It is indicated for assessing the patency and condition of bypass grafts, helping to determine their functionality and any potential complications.
  • Characterization of Atherosclerotic Plaques The imaging allows for detailed characterization of atherosclerotic plaques, which is crucial for planning further interventions or treatments.
  • Guidance for Interventional Procedures This imaging technique is often utilized to guide interventional procedures, ensuring accurate placement of devices and optimizing therapeutic outcomes.

2. Procedure

The procedure for endoluminal imaging of coronary vessels or grafts involves several key steps that ensure accurate and effective evaluation. The following outlines the procedural steps:

  • Step 1: Preparation The patient is prepared for the procedure, which may include sedation and local anesthesia, as well as the establishment of intravenous access for medication administration.
  • Step 2: Catheter Insertion A catheter is introduced into the vascular system, typically through the femoral or radial artery, and advanced to the coronary arteries or grafts using fluoroscopic guidance.
  • Step 3: Guidewire Placement A guidewire is positioned within the target vessel, providing a pathway for the IVUS or OCT catheter to follow.
  • Step 4: Imaging Catheter Advancement The imaging catheter, equipped with either a miniaturized transducer for IVUS or an optical fiber for OCT, is advanced over the guidewire to the site requiring evaluation.
  • Step 5: Image Acquisition The catheter is activated to obtain images of the vessel. For IVUS, ultrasound waves are emitted to create cross-sectional images, while OCT uses infrared light to generate high-resolution images.
  • Step 6: Image Interpretation The physician reviews the acquired images, assessing the structural integrity of the vessel, the presence of any lesions, and the overall condition of the coronary artery or graft.
  • Step 7: Reporting A comprehensive report is generated, detailing the findings from the imaging study, which is essential for guiding further clinical decisions.

3. Post-Procedure

After the endoluminal imaging procedure, patients are typically monitored for any immediate complications, such as bleeding or vascular access site issues. Depending on the patient's condition and the complexity of the procedure, they may be observed in a recovery area for a specified period. Instructions regarding activity restrictions, medication management, and follow-up appointments are provided to ensure optimal recovery and ongoing care. The physician will discuss the findings from the imaging report with the patient and outline any necessary next steps based on the results.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
LD Left anterior descending coronary artery
LC Left circumflex coronary artery
LM Left main coronary artery
RC Right coronary artery
GC This service has been performed in part by a resident under the direction of a teaching physician
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
RI Ramus intermedius coronary artery
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
