Official Description

Percutaneous arteriovenous fistula creation, upper extremity, separate access sites of the peripheral artery and peripheral vein, including fistula maturation procedures (eg, transluminal balloon angioplasty, coil embolization) when performed, including all vascular access, imaging guidance and radiologic supervision and interpretation

Common Language Description

A percutaneous arteriovenous fistula (AVF) creation is a minimally invasive surgical procedure designed specifically for patients with end-stage renal disease (ESRD) who require hemodialysis. This procedure involves the formation of a direct connection between a peripheral artery and a peripheral vein in the upper extremity, typically the arm, using separate access sites for each vessel. The primary goal of creating an AVF is to establish a reliable vascular access point that can withstand the repeated needle insertions required for hemodialysis treatments. The procedure is performed using image-guided techniques, which may include ultrasound and fluoroscopy, to accurately navigate and visualize the target vessels. During the procedure, the physician punctures the target vein under ultrasonic guidance, allowing for precise placement of a guidewire. This guidewire serves as a pathway for subsequent instruments, including dilators and sheaths, which facilitate access to the artery and vein. The use of advanced imaging techniques ensures that the physician can monitor the placement of the guidewires and catheters in real-time, enhancing the safety and efficacy of the procedure. Additionally, the AVF creation may involve various maturation procedures, such as transluminal balloon angioplasty or coil embolization, to optimize blood flow and ensure the fistula is functional for hemodialysis. The procedure concludes with imaging studies to confirm the patency of the newly created fistula and to assess blood flow dynamics. Overall, this procedure is critical for patients requiring long-term hemodialysis, as it provides a durable and effective means of vascular access.

1. Indications

The percutaneous arteriovenous fistula creation is indicated for patients with end-stage renal disease (ESRD) who require hemodialysis. The procedure is specifically performed to establish a reliable vascular access point that can accommodate the frequent needle insertions necessary for hemodialysis treatments. The following conditions may warrant the use of this procedure:

  • End-Stage Renal Disease (ESRD) Patients diagnosed with ESRD who are in need of hemodialysis for renal replacement therapy.
  • Need for Vascular Access Patients requiring a durable and effective means of vascular access for hemodialysis.

2. Procedure

The procedure for creating a percutaneous arteriovenous fistula involves several critical steps, each designed to ensure the successful formation of the fistula while minimizing complications.

  • Step 1: Patient Preparation The patient is positioned supine with the chosen arm extended to facilitate access to the upper extremity vessels. The area is sterilized, and local anesthesia is administered to minimize discomfort during the procedure.
  • Step 2: Accessing the Vein The target vein is punctured under ultrasonic guidance. A guidewire is inserted through the puncture site to facilitate further access. This step is crucial for ensuring accurate placement of instruments.
  • Step 3: Introducing the Dilator and Sheath Following the placement of the guidewire, a dilator is introduced to expand the vein, and a sheath is placed to maintain access. This allows for the subsequent introduction of catheters.
  • Step 4: Accessing the Artery The target artery is accessed separately, and an arteriogram is performed to visualize the arterial anatomy. This imaging step is essential for confirming the appropriate vessel for the fistula creation.
  • Step 5: Advancing the Venous Guidewire The venous guidewire is advanced under fluoroscopy to the intended anastomosis site, using the arterial guidewire as a visual aid. This ensures precise alignment of the vessels for the fistula.
  • Step 6: Performing a Venogram A venogram is conducted to confirm the presence of a perforator vein, which is necessary for the successful creation of the fistula.
  • Step 7: Advancing Catheters An arterial catheter is advanced over the guidewire to the target fistula site, while a venous catheter is inserted into the sheath and advanced to the same site. This dual access is critical for the creation of the AVF.
  • Step 8: Creating the Fistula The catheters are equipped with magnetic components that are aligned optimally. Radiofrequency energy is applied to create a permanent arteriovenous fistula, establishing the connection between the artery and vein.
  • Step 9: Angiogram of the New AVF An angiogram is obtained to verify the outflow in the cephalic or basilic vein, ensuring that the newly created fistula is functioning correctly.
  • Step 10: Coil Embolization A catheter is navigated to the brachial vein through the venous access site, and the brachial vein is occluded with coil embolization. This step directs more blood flow to the cephalic or basilic veins, enhancing the effectiveness of the fistula.
  • Step 11: Final Evaluation Repeat arteriography is performed to evaluate the fistula before the instruments are removed. Manual compression is applied to the access sites for at least 20 minutes to minimize bleeding.

3. Post-Procedure

After the completion of the percutaneous arteriovenous fistula creation, the patient is monitored for any immediate complications, such as bleeding or hematoma formation at the access sites. Manual compression is maintained for at least 20 minutes to ensure hemostasis. Patients may be advised to keep the access sites clean and dry, and to avoid heavy lifting or strenuous activities with the affected arm for a specified period to promote healing. Follow-up appointments are typically scheduled to assess the maturation of the fistula and its suitability for hemodialysis. Imaging studies may also be performed to evaluate the patency and function of the newly created AVF.

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).
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.
73 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure prior to the administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may cancel a surgical or diagnostic procedure subsequent to the patient's surgical preparation (including sedation when provided, and being taken to the room where the procedure is to be performed), but prior to the administration of anesthesia (local, regional block(s) or general). under these circumstances, the intended service that is prepared for but cancelled can be reported by its usual procedure number and the addition of modifier 73. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
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.)
