Official Description

Harvest of upper extremity artery, 1 segment, for coronary artery bypass procedure, endoscopic

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 33509 involves the harvesting of a segment of an upper extremity artery, typically the radial artery, for use in a coronary artery bypass grafting (CABG) procedure. This technique is performed using an endoscopic approach, which is a minimally invasive method that allows for the removal of the artery with smaller incisions compared to traditional open surgery. The endoscopic method not only enhances the cosmetic outcome by minimizing scarring but also reduces the risk of postoperative complications such as infections and shortens the duration of hospital stays. However, it is important to note that this technique carries certain risks, including a higher likelihood of radial nerve injury and potential hand numbness due to the manipulation of the surrounding tissues. The procedure begins with a small incision made over the radial artery, followed by careful dissection to isolate the artery and its accompanying veins, ensuring that they are preserved as a single pedicle to minimize trauma. The use of an endoscope facilitates the dissection process, allowing for a more controlled and precise approach to harvesting the artery segment needed for grafting in the CABG procedure.

1. Indications

The harvesting of an upper extremity artery segment, specifically for use in coronary artery bypass procedures, is indicated in the following scenarios:

  • Coronary Artery Disease Patients with significant coronary artery disease requiring bypass grafting to restore adequate blood flow to the heart.
  • Previous Graft Failure Individuals who have experienced failure of previous grafts and require additional grafting for effective treatment.
  • Insufficient Vein Harvest Cases where there is inadequate availability of saphenous vein for grafting, necessitating the use of arterial grafts.

2. Procedure

The procedure for harvesting the upper extremity artery segment involves several detailed steps:

  • Step 1: Incision A 3 cm longitudinal incision is made in the arm, specifically over the radial artery, just proximal to the wrist crease. This incision allows access to the underlying structures while minimizing tissue damage.
  • Step 2: Dissection The incision is deepened through the lateral fascia until the radial artery and its accompanying veins are identified. These structures are carefully dissected as a single pedicle to prevent direct trauma to the artery, ensuring its viability for grafting.
  • Step 3: Endoscope Insertion The tip of the endoscope is advanced over the artery, allowing for visualization and manipulation of the surrounding tissues. A port is then inserted and inflated with air to create a sealed tunnel, facilitating the endoscopic dissection.
  • Step 4: Artery Dissection Using the endoscopic tip, the radial artery is dissected in a posterior to anterior direction. This technique allows for precise control during the harvesting process.
  • Step 5: Vessel Cannulation The endoscopic tip is removed, and the endoscope is placed in a specialized vessel harvesting cannula. This cannula is designed to grasp and secure the artery during the harvesting process.
  • Step 6: Tissue Grasping The fascia is opened, and the tissues are grasped between the jaws of the cannula. The tool is then pulled and rotated to capture the artery and its branches effectively.
  • Step 7: Division and Ligation Once the entire artery pedicle is captured, it is divided and ligated in the antecubital fossa, ensuring that the artery is fully detached for use as a graft.
  • Step 8: Graft Preparation The harvested radial artery is prepared for grafting by flushing it with papaverine, a vasodilator, and clipping the branches to ensure it is ready for implantation in the coronary artery bypass procedure.

3. Post-Procedure

After the harvesting procedure, patients are typically monitored for any signs of complications, such as nerve injury or excessive bleeding. The incision site is usually closed with sutures, and care instructions are provided to promote healing. Patients may experience some discomfort or numbness in the hand, which should be monitored. Follow-up appointments are essential to assess the healing process and ensure that the harvested artery is functioning properly for its intended use in the bypass grafting procedure.

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.
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
LT Left side (used to identify procedures performed on the left side of the body)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
GC This service has been performed in part by a resident under the direction of a teaching physician
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
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).
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).
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.
