Official Description

Ligation, major artery (eg, post-traumatic, rupture); extremity

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 37618 involves the ligation of a major artery in an extremity, which is typically performed to control significant bleeding resulting from a rupture or traumatic injury to the blood vessel. In this context, "ligation" refers to the surgical technique of tying off the artery to prevent further blood loss. The procedure begins with the physician making an incision to access the site of injury, allowing for exploration of the affected area. During this exploration, any accumulated blood is evacuated, and the source of the bleeding is identified. A vascular clamp is then applied to temporarily control the bleeding, enabling the surgeon to thoroughly examine the site for any additional injuries that may require attention. Once the area is adequately assessed, the artery is carefully dissected away from the surrounding tissues to facilitate the placement of a suture ligature or wire band. This dissection is crucial as it ensures that the artery can be securely tied off at a point proximal to the rupture, effectively stopping the flow of blood and preventing further complications. It is important to note that this specific code is designated for ligation procedures performed on major arteries located in the arms or legs. For ligation of major arteries in other anatomical locations, such as the neck, chest, or abdomen, different CPT® codes are utilized, specifically 37615, 37616, and 37617, respectively. This distinction is essential for accurate coding and billing purposes.

1. Indications

The ligation of a major artery in an extremity is indicated in specific clinical scenarios where there is a need to control significant hemorrhage. The following conditions may warrant this procedure:

  • Post-Traumatic Bleeding - This procedure is often performed following traumatic injuries that result in the rupture of a major artery, leading to uncontrolled bleeding.
  • Rupture of Blood Vessels - Situations involving the rupture of major arteries due to various causes, including accidents or severe blunt force trauma, necessitate immediate surgical intervention to prevent life-threatening blood loss.

2. Procedure

The procedure for ligation of a major artery in an extremity involves several critical steps to ensure effective control of bleeding. The following outlines the procedural steps:

  • Step 1: Incision and Exploration - The surgeon begins by making an incision at the site of the injury to gain access to the affected area. This incision allows for direct visualization and exploration of the injury site.
  • Step 2: Evacuation of Blood - Once the incision is made, any pooled blood in the area is evacuated. This step is essential to provide a clear view of the injury and to facilitate the identification of the source of bleeding.
  • Step 3: Application of Vascular Clamp - A vascular clamp is applied to the artery to temporarily control the bleeding. This clamp helps to minimize blood loss during the exploration and subsequent steps of the procedure.
  • Step 4: Identification of Additional Injuries - The surgeon thoroughly examines the site for any other potential injuries that may require treatment. This comprehensive assessment is crucial for ensuring that all injuries are addressed.
  • Step 5: Dissection of the Artery - The major artery is carefully dissected free from surrounding tissues. This dissection is performed to allow for the placement of a suture ligature or wire band around the artery.
  • Step 6: Ligation of the Artery - Finally, the artery is tied off using sutures or a thin wire at a point proximal to the rupture. This step effectively stops the flow of blood through the artery, controlling the hemorrhage and stabilizing the patient.

3. Post-Procedure

After the ligation procedure is completed, the patient will require careful monitoring to assess for any complications, such as infection or further bleeding. Post-operative care may include pain management, wound care, and observation for signs of vascular compromise in the affected extremity. The recovery process will vary depending on the extent of the injury and the patient's overall health. Follow-up appointments will be necessary to evaluate the healing process and to ensure that the ligation has effectively controlled the bleeding without causing additional complications.

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).
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.
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).
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).
