Official Description

Exploration not followed by surgical repair, artery; neck (eg, carotid, subclavian)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An exploration of the artery in the neck, specifically the carotid or subclavian artery, is a surgical procedure that involves examining the artery without performing any surgical repair. This procedure is indicated when there is a need to assess the condition of the artery, which may be affected by various factors such as disease or injury. During the exploration, an incision is made directly over the target artery, allowing the surgeon to access and visualize the artery clearly. The surrounding soft tissue is carefully dissected to provide a clear view of the artery, enabling the surgeon to inspect it for any signs of constriction, damage, or other abnormalities. If the artery is found to be constricted due to adhesions, the surgeon may perform lysis, which involves cutting or removing the adhesions to relieve the constriction. Additionally, if the artery is kinked, further lysis of the surrounding tissue may be necessary to straighten the artery and enhance blood flow. Once the exploration is complete, the incision is meticulously closed in layers to promote proper healing. This procedure is coded as CPT® Code 35701, distinguishing it from similar procedures involving upper and lower extremity arteries, which are coded differently.

1. Indications

The exploration of the neck artery is performed for specific indications that may include the following:

  • Assessment of Arterial Disease The procedure is indicated when there is a suspicion of arterial disease affecting the carotid or subclavian artery, which may include conditions such as atherosclerosis or thrombosis.
  • Evaluation of Injury It is performed to evaluate the artery for any signs of injury, which may have resulted from trauma or surgical complications.
  • Investigation of Symptoms The procedure may be indicated in patients presenting with symptoms such as transient ischemic attacks (TIAs) or strokes, where arterial blockage or narrowing is suspected.

2. Procedure

The procedure involves several key steps that are crucial for successful exploration of the artery:

  • Step 1: Incision An incision is made over the target artery, typically in the neck region, to provide access to the carotid or subclavian artery. The location of the incision is carefully chosen to minimize trauma to surrounding structures.
  • Step 2: Dissection The surrounding soft tissue is meticulously dissected to expose the artery. This step is essential for visualizing the artery and assessing its condition. Care is taken to avoid damaging nearby nerves and vessels during this dissection.
  • Step 3: Inspection Once the artery is exposed, the surgeon inspects it for any evidence of disease or injury. This visual examination allows for the identification of issues such as constriction, kinking, or other abnormalities that may affect blood flow.
  • Step 4: Lysis of Adhesions If the artery is found to be constricted due to adhesions, the surgeon performs lysis to remove these adhesions. This step is critical for restoring normal blood flow through the artery.
  • Step 5: Straightening of the Artery In cases where the artery is kinked, additional lysis of surrounding tissue may be necessary to straighten the artery. This intervention helps to improve blood flow and reduce the risk of complications.
  • Step 6: Closure After the exploration and any necessary interventions are completed, the incision is closed in layers. This layered closure technique is important for promoting proper healing and minimizing scarring.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any signs of complications, such as bleeding or infection at the incision site. Patients may be advised to rest and avoid strenuous activities for a specified period to facilitate healing. Follow-up appointments may be scheduled to assess recovery and ensure that the artery is functioning properly. Any specific instructions regarding wound care and activity restrictions will be provided by the healthcare team to support optimal recovery.

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).
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).
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.
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).
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).
