Official Description

Exploration not followed by surgical repair, artery; upper extremity (eg, axillary, brachial, radial, ulnar)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An exploration of the upper extremity artery, as described by CPT® Code 35702, involves a surgical procedure where the artery is examined without subsequent surgical repair. This procedure may include lysis, which is the process of breaking down adhesions or scar tissue that may be constricting the artery. The exploration begins with an incision made directly over the target artery, which could be one of the major arteries in the upper extremity, such as the axillary, brachial, radial, or ulnar arteries. Once the incision is made, the surrounding soft tissue is carefully dissected to provide clear visibility of the artery. During the exploration, the artery is thoroughly inspected for any signs of disease or injury that may be affecting blood flow. If any constrictions are found, such as those caused by adhesions, the surgeon may perform lysis to alleviate these issues. Additionally, if the artery is kinked, further lysis of the surrounding tissue may be necessary to straighten the artery and enhance blood circulation. After the exploration is completed, the incision is meticulously closed in layers to promote proper healing. It is important to note that this code is specifically for the exploration of upper extremity arteries, and different codes are designated for explorations of neck and lower extremity arteries.

1. Indications

The procedure described by CPT® Code 35702 is indicated for various conditions affecting the upper extremity arteries. These may include:

  • Evidence of arterial disease - This may involve conditions such as atherosclerosis or other forms of vascular disease that compromise blood flow.
  • Trauma or injury - Situations where the artery may have been damaged due to an accident or surgical intervention, necessitating exploration to assess the extent of the injury.
  • Symptoms of vascular insufficiency - Patients may present with symptoms such as pain, numbness, or weakness in the upper extremity, prompting the need for exploration to identify underlying arterial issues.
  • Presence of kinks or constrictions - Conditions where the artery is kinked or constricted due to adhesions or other factors, which may require intervention to restore normal blood flow.

2. Procedure

The procedure for CPT® Code 35702 involves several key steps, which are detailed as follows:

  • Step 1: Incision - The procedure begins with the surgeon making an incision over the target artery in the upper extremity. The location of the incision is determined based on the specific artery being explored, such as the axillary, brachial, radial, or ulnar artery.
  • Step 2: Dissection - Following the incision, the surrounding soft tissue is carefully dissected to expose the artery. This dissection is performed with precision to minimize damage to adjacent structures and to provide adequate visualization of the artery.
  • Step 3: Inspection - Once the artery is exposed, the surgeon inspects it for any signs of disease or injury. This inspection is critical for identifying any abnormalities that may be affecting blood flow.
  • Step 4: Lysis of Adhesions - If the artery is found to be constricted due to adhesions, the surgeon performs lysis to break down these adhesions. This step is essential for restoring normal arterial function and improving blood flow.
  • Step 5: Addressing Kinks - In cases where the artery is kinked, additional lysis of surrounding tissue may be necessary to straighten the artery. This intervention helps to alleviate any obstruction to blood flow.
  • 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 the risk of complications.

3. Post-Procedure

Post-procedure care following the exploration of the upper extremity artery involves monitoring the surgical site for signs of infection or complications. Patients may be advised to keep the incision clean and dry, and to follow any specific instructions provided by the healthcare provider regarding activity restrictions. Recovery time may vary depending on the extent of the procedure and the patient's overall health. Follow-up appointments may be scheduled to assess healing and to ensure that normal blood flow has been restored. It is important for patients to report any unusual symptoms, such as increased pain, swelling, or changes in sensation in the upper extremity, to their healthcare provider promptly.

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
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).
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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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.
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).
