Official Description

Exploration not followed by surgical repair, artery; lower extremity (eg, common femoral, deep femoral, superficial femoral, popliteal, tibial, peroneal)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An exploration of the lower extremity artery, coded as CPT® 35703, involves a surgical procedure where the artery is examined without subsequent surgical repair. This procedure is typically 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 targeted artery, which can include arteries such as the common femoral, deep femoral, superficial femoral, popliteal, tibial, or peroneal arteries. The surrounding soft tissue is carefully dissected to provide clear visibility of the artery. The primary goal of this exploration is to inspect the artery for any signs of constriction, damage, or other abnormalities. If any adhesions are found that are causing constriction, they may be lysed to relieve the pressure on the artery. 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. It is important to note that this code is specific to lower extremity arteries, and different codes are used for explorations of neck and upper extremity arteries.

1. Indications

The procedure coded as CPT® 35703 is indicated for the exploration of lower extremity arteries in cases where there is a suspicion of arterial disease or injury. This may include conditions such as:

  • Arterial Occlusion: Blockage of the artery that may impede blood flow.
  • Arterial Aneurysm: A bulging or dilation of the artery that may pose a risk of rupture.
  • Trauma: Injury to the artery that may require assessment for damage.
  • Peripheral Artery Disease: A condition characterized by narrowed arteries reducing blood flow to the limbs.

2. Procedure

The procedure involves several key steps to ensure a thorough exploration of the artery:

  • Step 1: Incision An incision is made over the targeted artery in the lower extremity. The location of the incision is determined based on the specific artery being examined, such as the common femoral, deep femoral, superficial femoral, popliteal, tibial, or peroneal artery.
  • Step 2: Dissection Surrounding soft tissue is carefully dissected to provide adequate visualization of the artery. This step is crucial for accessing the artery without causing unnecessary damage to adjacent structures.
  • Step 3: Inspection The artery is inspected for any signs of disease or injury. This includes checking for constrictions, blockages, or any other abnormalities that may affect blood flow.
  • Step 4: Lysis of Adhesions If the artery is found to be constricted due to adhesions, these are lysed to relieve the constriction. This may involve cutting through fibrous tissue that is causing the artery to be narrowed.
  • Step 5: Straightening of the Artery In cases where the artery is kinked, additional lysis of surrounding tissue may be performed to allow for straightening of the artery. This step is essential to improve blood flow through the artery.
  • Step 6: Closure After the exploration and any necessary interventions are completed, the incision is closed in layers. This layered closure helps to promote healing and reduce the risk of complications.

3. Post-Procedure

Post-procedure care following the exploration of the lower extremity artery includes monitoring the surgical site for signs of infection, ensuring proper healing, and managing any discomfort. Patients may be advised to limit physical activity for a specified period to allow for recovery. Follow-up appointments may be scheduled to assess the healing process and to determine if further interventions are necessary based on the findings from the exploration.

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).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
LT Left side (used to identify procedures performed on the left side of the body)
RT Right side (used to identify procedures performed on the right side of the body)
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).
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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
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).
CR Catastrophe/disaster related
GC This service has been performed in part by a resident under the direction of a teaching physician
X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
