Common Language Description

The CPT® Code 34705 refers to the endovascular repair of the infrarenal aorta and/or iliac artery(ies) utilizing an aorto-bi-iliac endograft. This procedure is primarily indicated for conditions such as aneurysms, pseudoaneurysms, dissections, or penetrating ulcers, rather than for ruptured vessels. The endograft is a sophisticated medical device made from a non-permeable polyester material, which is reinforced by a self-expanding flexible metal frame. The design of the aorto-bi-iliac endograft includes a main body that fits within the aorta and tapered limbs that extend into the iliac arteries, which can be either a unibody or modular configuration. During the procedure, a guidewire is inserted into the abdominal aorta through the femoral artery or the distal external iliac arteries. The endograft is then carefully positioned below the renal arteries using fluoroscopic imaging to ensure accurate placement. The deployment process involves partially releasing the endograft, ensuring that the upper aortic end is correctly positioned to create a secure seal with the non-aneurysmal aortic neck and the iliac artery. In cases where a modular endograft is used, a second guidewire is introduced through the contralateral iliac artery to facilitate the deployment of the contralateral limb of the endograft. The procedure also includes angioplasty and stenting as necessary to ensure a tight fit and prevent any potential leakage around the graft. Following the deployment, the sheaths and guidewires are removed, and the femoral arteries are repaired. This endovascular approach is crucial for managing vascular conditions effectively, as it minimizes the risk of complications associated with open surgical procedures and promotes quicker recovery times for patients.

1. Indications

The endovascular repair of the infrarenal aorta and/or iliac artery(ies) using an aorto-bi-iliac endograft is indicated for the following conditions:

  • Aneurysm - A localized enlargement of the aorta that can lead to rupture if not treated.
  • Pseudoaneurysm - A false aneurysm that occurs when blood leaks out of the artery but is contained by surrounding tissue.
  • Dissection - A serious condition where there is a tear in the artery wall, allowing blood to flow between the layers of the wall.
  • Pentrating Ulcer - A condition where an ulcer penetrates the arterial wall, potentially leading to serious complications.

2. Procedure

The procedure for endovascular repair of the infrarenal aorta and/or iliac artery(ies) involves several critical steps:

  • Step 1: Pre-Procedure Sizing and Device Selection - Prior to the procedure, careful measurements are taken to determine the appropriate size and type of endograft required for the patient's anatomy. This ensures optimal fit and function of the device once deployed.
  • Step 2: Catheterization - Nonselective catheterization is performed to access the vascular system. A guidewire is introduced into the abdominal aorta through the femoral artery and/or distal external iliac arteries, allowing for the subsequent placement of the endograft.
  • Step 3: Deployment of the Endograft - The main body of the endograft is introduced over the guidewire and positioned below the renal arteries. Fluoroscopic guidance is utilized to ensure accurate placement. The endograft is then partially deployed, with the upper aortic end positioned proximally to the non-aneurysmal aortic neck and distally to the iliac artery.
  • Step 4: Deployment of Contralateral Limb - For modular endografts, a second guidewire is introduced through the contralateral iliac artery to facilitate the deployment of the contralateral limb. A stent is deployed over this guidewire and anchored to the vessel wall, ensuring a secure fit.
  • Step 5: Deployment of Ipsilateral Limb - The ipsilateral limb of the stent graft is deployed in a similar manner, ensuring sufficient overlap to prevent leakage around the main body of the endograft and the proximal end of the limb.
  • Step 6: Angioplasty - A balloon is introduced and used to expand all graft-to-vessel and graft-to-graft junctions in a proximal to distal direction, ensuring a tight seal and optimal blood flow through the graft.
  • Step 7: Removal of Sheaths and Guidewires - After successful deployment and expansion of the endograft, the sheaths and guidewires are carefully removed from the vascular system.
  • Step 8: Repair of Femoral Arteries - Finally, the femoral artery(ies) are repaired to complete the procedure, ensuring hemostasis and restoring normal blood flow.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any complications, such as bleeding or graft-related issues. Patients are typically observed for a period to ensure stability and proper recovery. Follow-up imaging may be required to assess the integrity of the endograft and ensure that there are no leaks or other complications. The recovery process may vary depending on the individual patient's condition and the complexity of the procedure performed.

AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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.
GC This service has been performed in part by a resident under the direction of a teaching physician
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).
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
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.
25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
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.
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.)
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
