Official Description

Revascularization, endovascular, open or percutaneous, iliac artery, each additional ipsilateral iliac vessel; with transluminal angioplasty (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 37222 refers to the procedure of revascularization of an additional ipsilateral iliac vessel through endovascular means, which can be performed either via an open or percutaneous approach. This procedure is specifically indicated for patients with occluded or stenosed iliac arteries, where the physician employs angioplasty techniques to restore blood flow. In the context of this procedure, 'revascularization' means the restoration of blood supply to the affected artery, which is crucial for preventing complications associated with reduced blood flow, such as ischemia. The term 'iliac artery' refers to the large arteries that supply blood to the pelvis and lower limbs, and 'ipsilateral' indicates that the procedure is performed on the same side of the body as the primary intervention. The use of transluminal angioplasty involves the insertion of a balloon catheter to dilate the narrowed artery, thereby compressing plaque against the arterial wall to improve blood flow. This code is used in conjunction with other related codes, such as 37220 for the initial iliac artery treated, and it is important to note that it is listed separately in addition to the primary procedure code. The detailed steps involved in this procedure ensure that the physician can effectively address vascular blockages while minimizing patient risk and promoting recovery.

1. Indications

The procedure associated with CPT® Code 37222 is indicated for patients experiencing conditions related to occlusion or stenosis of the iliac artery. These conditions may include:

  • Occluded Iliac Artery The artery is completely blocked, preventing blood flow.
  • Stenosed Iliac Artery The artery is narrowed, which restricts blood flow and can lead to symptoms such as claudication or limb ischemia.

2. Procedure

The procedure for CPT® Code 37222 involves several critical steps to ensure successful revascularization of the iliac artery. The following procedural steps are outlined:

  • Step 1: Access Preparation If an open approach is utilized, the skin over the access artery is prepped and incised to expose the artery. In a percutaneous approach, the skin over the access artery, typically one of the femoral arteries, is prepped, and a needle is used to puncture the artery, followed by the placement of a sheath.
  • Step 2: Guidewire Insertion A guidewire is inserted through the sheath and advanced from the access artery into the occluded iliac artery. Radiological supervision is employed as necessary, and roadmapping angiograms are obtained to visualize the anatomy and the extent of the occlusion.
  • Step 3: Balloon Catheter Advancement A catheter with a balloon tip is advanced over the guidewire to the site of the occlusion. The balloon is then inflated, compressing the plaque against the arterial wall. This inflation may be repeated several times to achieve optimal results.
  • Step 4: Completion Angiography After angioplasty, the angioplasty catheter is exchanged for a guidewire, and an angiography catheter is advanced over the guidewire. The guidewire is then withdrawn, and contrast material is injected to perform a completion angiography, ensuring that the artery is patent.
  • Step 5: Stent Placement (if necessary) If an intravascular stent is required to maintain the artery's patency, the stent delivery catheter is advanced to the lesion site. The stent is carefully positioned and deployed, followed by the removal of the stent delivery catheter. A balloon catheter may be advanced and inflated again to properly seat the stent.
  • Step 6: Closure After all catheters are removed, if an open approach was used, the access artery is repaired, and the skin incision is closed. In the case of a percutaneous approach, pressure is applied to the vascular access site, and a pressure dressing is applied to ensure hemostasis.

3. Post-Procedure

Post-procedure care for patients undergoing the revascularization procedure coded under CPT® 37222 includes monitoring for any complications such as bleeding or hematoma at the access site. Patients may be advised to rest and limit physical activity for a specified period to promote healing. Follow-up appointments are typically scheduled to assess the success of the procedure and to monitor the patency of the treated artery. Documentation of the procedure and any findings during the completion angiography is essential for future reference and continuity of care.

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).
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.
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).
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.
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.
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).
