Official Description

Open brachial artery exposure for delivery of endovascular prosthesis, unilateral (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 34834 involves the surgical exposure of the brachial artery to facilitate the delivery of an endovascular prosthesis. This procedure is performed unilaterally, meaning it is conducted on one side of the body. The brachial artery, located in the upper arm, is carefully accessed through an incision, ensuring that surrounding nerves and blood vessels are adequately protected and mobilized to prevent any damage. The dissection of the brachial artery is performed over a length of approximately 5 to 6 centimeters, allowing for sufficient access to the artery. Once exposed, the artery is secured using vessel loops to maintain its position during the procedure. An incision is then made in the brachial artery itself, through which guidewires, sheaths, and catheters are introduced as necessary to assist in the delivery of the endovascular prosthesis. This prosthesis is typically utilized for repairs related to defects in the aorta or iliac arteries. After the endovascular procedure is completed, the brachial artery is meticulously repaired, followed by a layered closure of the surgical wound. It is important to note that this code is reported separately in addition to the code for the primary procedure being performed.

1. Indications

The procedure indicated by CPT® Code 34834 is performed for specific clinical scenarios where access to the brachial artery is necessary to deliver an endovascular prosthesis. The following conditions may warrant this procedure:

  • Aortic Defect Repair The procedure may be indicated for patients requiring repair of defects in the aorta, necessitating the placement of an endovascular prosthesis.
  • Iliac Defect Repair Similarly, this procedure is indicated for iliac artery defects, where an endovascular approach is required to restore vascular integrity.

2. Procedure

The procedural steps for CPT® Code 34834 are as follows:

  • Step 1: Incision An incision is made in the upper arm to access the brachial artery. This step is critical as it allows the surgeon to reach the artery while taking care to protect surrounding structures, including nerves and blood vessels.
  • Step 2: Dissection The brachial artery is then dissected free from the surrounding tissue over a length of 5 to 6 centimeters. This careful dissection is essential to ensure that the artery is adequately exposed for the subsequent steps.
  • Step 3: Securing the Artery Once the artery is adequately exposed, it is secured with vessel loops. This stabilization is necessary to maintain access to the artery during the procedure.
  • Step 4: Incision of the Brachial Artery An incision is made in the brachial artery itself. This step is crucial as it allows for the introduction of guidewires, sheaths, and catheters that will facilitate the delivery of the endovascular prosthesis.
  • Step 5: Delivery of Endovascular Prosthesis The necessary guidewires, sheaths, and catheters are placed as needed to assist in the delivery of the endovascular prosthesis, which is typically used for repairing defects in the aorta or iliac arteries.
  • Step 6: Repair of the Brachial Artery After the endovascular procedure is completed, the brachial artery is repaired to restore its integrity and function.
  • Step 7: Wound Closure Finally, the surgical wound is repaired in layers to ensure proper healing and minimize complications.

3. Post-Procedure

Post-procedure care following the exposure of the brachial artery for the delivery of an endovascular prosthesis includes monitoring for any signs of complications such as bleeding, infection, or vascular compromise. Patients may require follow-up imaging studies to assess the success of the endovascular repair. Additionally, instructions regarding activity restrictions and wound care will be provided to ensure optimal recovery. The surgical site should be kept clean and dry, and any signs of unusual swelling or discharge should be reported to the healthcare provider promptly.

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.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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).
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.
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.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
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).
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).
