Official Description

Percutaneous transcatheter placement of intracoronary stent(s), with coronary angioplasty when performed; each additional branch of a major coronary artery (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 92929 involves the percutaneous transcatheter placement of intracoronary stent(s) in conjunction with coronary angioplasty, specifically for each additional branch of a major coronary artery. This procedure is typically indicated when there is a narrowing or blockage (stenosis) in the coronary arteries, which can lead to reduced blood flow to the heart muscle and potentially result in angina or myocardial infarction. A stent, which is a small wire mesh tube, is utilized to support the artery walls and maintain patency in the affected segment. The procedure begins with the preparation of the skin over the access artery, often the femoral artery, followed by puncturing the artery to insert a sheath. A guidewire is then navigated through the aorta into the occluded coronary artery. Following this, a balloon-tipped catheter is advanced to the site of the blockage, where percutaneous transluminal coronary angioplasty (PTCA) is performed. This involves inflating the balloon to compress the plaque against the artery wall, which may be repeated multiple times to achieve optimal results. Subsequently, a compressed stent is delivered to the site using the balloon catheter, and once positioned correctly, the balloon is inflated to expand the stent, effectively creating a scaffold that keeps the artery open. Finally, contrast material is injected, and completion angiography is conducted to confirm that the treated artery remains patent. It is important to note that CPT® Code 92929 is used specifically for each additional branch of a major coronary artery that is treated, while CPT® Code 92928 is designated for stent placement in a single major coronary artery or branch.

1. Indications

The procedure associated with CPT® Code 92929 is indicated for patients experiencing significant coronary artery stenosis or occlusion that necessitates intervention to restore adequate blood flow to the heart. The following conditions may warrant the use of this procedure:

  • Coronary Artery Disease (CAD) - A condition characterized by the narrowing of coronary arteries due to atherosclerosis, leading to reduced blood flow to the heart muscle.
  • Angina Pectoris - Chest pain or discomfort that occurs when the heart muscle does not receive enough blood, often triggered by physical activity or stress.
  • Myocardial Infarction - A medical emergency where blood flow to a part of the heart is blocked, resulting in damage to the heart muscle, often requiring urgent intervention.
  • Recurrent Symptoms After Previous Interventions - Patients who have previously undergone coronary interventions but continue to experience symptoms may require additional stenting in other branches of the coronary arteries.

2. Procedure

The procedure for CPT® Code 92929 involves several critical steps to ensure successful placement of the intracoronary stent. The following outlines the procedural steps:

  • Step 1: Patient Preparation - The patient is positioned comfortably, and the access site, typically the femoral artery, is cleaned and sterilized to prevent infection. Sedation may be administered to ensure patient comfort during the procedure.
  • Step 2: Accessing the Artery - A needle is used to puncture the skin over the access artery, and a sheath is inserted to provide a pathway for the guidewire and catheter. This step is crucial for gaining access to the vascular system.
  • Step 3: Guidewire Insertion - A guidewire is carefully threaded through the sheath and advanced through the aorta into the coronary artery that is narrowed or blocked. This guidewire serves as a track for subsequent catheter placement.
  • Step 4: Balloon Angioplasty - A balloon-tipped catheter is advanced over the guidewire to the site of the occlusion. The balloon is inflated at the site of the blockage, compressing the plaque against the artery wall to widen the artery and improve blood flow. This inflation may be repeated multiple times to achieve the desired dilation.
  • Step 5: Stent Delivery - Once the artery is adequately dilated, a stent that is compressed onto a balloon catheter is positioned at the site. The balloon is inflated again to expand the stent, which then holds the artery open, preventing re-narrowing.
  • Step 6: Completion Angiography - After the stent is deployed, contrast material is injected through the catheter, and completion angiography is performed to visualize the treated artery and confirm that it is patent and functioning properly.

3. Post-Procedure

After the completion of the procedure associated with CPT® Code 92929, the patient is typically monitored in a recovery area for any immediate complications. Post-procedure care may include the following considerations:

  • Monitoring - Vital signs are closely monitored, and the access site is checked for any signs of bleeding or hematoma formation.
  • Medications - Patients may be prescribed antiplatelet medications to prevent clot formation on the stent and reduce the risk of future cardiovascular events.
  • Activity Restrictions - Patients are often advised to limit physical activity for a specified period to allow for proper healing and to avoid strain on the access site.
  • Follow-Up Appointments - Regular follow-up visits are essential to assess the stent's function and the patient's overall cardiovascular health.

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.
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
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.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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).
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
