Official Description

Open femoral artery exposure for delivery of endovascular prosthesis, by groin incision, 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 34812 involves the surgical exposure of the femoral artery to facilitate the delivery of an endovascular prosthesis. This is achieved through a unilateral groin incision, which means that the incision is made on one side of the groin area. The process begins with an incision through the skin over the groin, followed by careful dissection of the subcutaneous tissue to reach the common femoral artery. During this dissection, it is crucial to protect the surrounding structures, particularly the femoral nerve and vein, to prevent any potential complications. Once the common femoral artery is accessed, the surgeon also dissects the superficial and deep femoral arteries, ensuring they are free from surrounding tissue and can be manipulated as needed. Vessel loops are used to capture these arteries for better visibility and access. In some cases, the distal external iliac artery may also be dissected, which may require the retraction or division of the inguinal ligament to gain adequate access. Additionally, any small branch arteries encountered during the procedure are typically ligated or cauterized to minimize bleeding. The femoral artery is then clamped and incised, allowing for the introduction of guide wires and sheaths necessary for the subsequent placement of the endovascular device. It is important to note that this procedure is reported separately and in conjunction with a primary procedure, highlighting its role as a preparatory step in the overall endovascular intervention.

1. Indications

The procedure described by CPT® Code 34812 is indicated for patients requiring endovascular intervention involving the femoral artery. This may include conditions such as:

  • Peripheral Artery Disease (PAD) - A condition characterized by narrowed arteries reducing blood flow to the limbs, often requiring endovascular treatment.
  • Aneurysms - The presence of an abnormal bulge in the artery wall that may necessitate the placement of a prosthesis to reinforce the vessel.
  • Arterial Occlusions - Blockages in the artery that can lead to ischemia, where blood flow is insufficient to meet the needs of the tissues.

2. Procedure

The procedure for open femoral artery exposure for the delivery of an endovascular prosthesis involves several critical steps:

  • Step 1: Incision - The surgeon begins by making an incision through the skin over the groin area, which serves as the entry point for the procedure.
  • Step 2: Dissection of Subcutaneous Tissue - Following the incision, the subcutaneous tissue is carefully dissected to expose the underlying structures, particularly the common femoral artery. This step requires meticulous attention to avoid damaging nearby nerves and veins.
  • Step 3: Exposure of Femoral Arteries - The common, superficial, and deep femoral arteries are then dissected free from surrounding tissue. This is done to ensure that these arteries are accessible for the subsequent steps of the procedure.
  • Step 4: Use of Vessel Loops - Once the femoral arteries are exposed, vessel loops are employed to capture and hold these arteries in place, providing better visibility and access for the surgeon.
  • Step 5: Dissection of the Distal External Iliac Artery - If necessary, the distal external iliac artery may also be dissected. This may involve retracting or dividing the inguinal ligament to facilitate access to the artery.
  • Step 6: Ligation or Cauterization of Branch Arteries - Any small branch arteries encountered during the dissection are ligated or cauterized to control bleeding and maintain a clear surgical field.
  • Step 7: Clamping and Incision of the Femoral Artery - The femoral artery is then clamped to prevent blood flow, and an incision is made to allow for the introduction of guide wires and sheaths necessary for the endovascular procedure.

3. Post-Procedure

After the completion of the open femoral artery exposure, post-procedure care typically involves monitoring the patient for any signs of complications, such as bleeding or infection at the incision site. The patient may be advised to rest and limit physical activity for a specified period to promote healing. Follow-up appointments are essential to assess the surgical site and ensure proper recovery. Additionally, the healthcare team will provide instructions regarding wound care and any necessary medications to manage pain or prevent infection.

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.
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.
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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.
