Official Description

Repair, primary, torn ligament and/or capsule, knee; cruciate

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 27407 pertains to the primary repair of torn ligaments and/or the joint capsule in the knee, specifically focusing on the cruciate ligaments, which include the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). The knee joint is stabilized by four major ligaments: the ACL and PCL, which are located centrally within the knee, and the medial collateral ligament (MCL) and lateral collateral ligament (LCL), which are positioned on the inner and outer aspects of the knee, respectively. The ACL and PCL are crucial for providing rotational stability to the knee, and injuries to these ligaments can lead to significant instability, causing the knee to buckle during movement. In cases where the ACL or PCL is torn, surgical intervention may be necessary to restore stability and function to the knee. The procedure involves making a skin incision over the affected area, followed by dissection of the soft tissues to expose the damaged ligament. The repair process includes suturing the torn ligament and, if necessary, using suture anchors to reinforce the repair. Additionally, any associated tears in the joint capsule are also addressed during the procedure. It is important to note that this code is specifically designated for the primary repair of the ACL or PCL and/or the joint capsule, distinguishing it from other codes that pertain to repairs of the MCL or LCL, or for multi-ligament injuries.

1. Indications

The procedure associated with CPT® Code 27407 is indicated for the following conditions:

  • Torn Anterior Cruciate Ligament (ACL) - This condition occurs when the ACL, a key ligament in the knee, is torn, leading to instability and difficulty in performing activities that involve pivoting or sudden changes in direction.
  • Torn Posterior Cruciate Ligament (PCL) - Similar to the ACL, a tear in the PCL can result in knee instability, particularly during activities that require knee flexion or weight-bearing.
  • Joint Capsule Injury - Injuries to the joint capsule, which may accompany ligament tears, can also necessitate surgical repair to restore the integrity and function of the knee joint.

2. Procedure

The procedure for repairing a torn ligament and/or capsule in the knee, specifically the cruciate ligaments, involves several key steps:

  • Step 1: Incision - A skin incision is made over the area of the knee where the ligament injury has occurred. This incision allows access to the underlying structures of the knee joint.
  • Step 2: Dissection of Soft Tissues - The surgeon carefully dissects the soft tissues surrounding the knee to expose the damaged ligament. This step is crucial for visualizing the extent of the injury and planning the repair.
  • Step 3: Inspection of the Ligament - If the injury involves an isolated tear of the MCL or LCL, the surgeon will expose and inspect the involved ligament to assess the damage. For ACL or PCL injuries, the joint capsule is incised to allow for a thorough inspection of the knee joint.
  • Step 4: Repair of the Torn Ligament - The torn ligament is repaired using sutures. In some cases, suture anchors may be utilized to provide additional support to the repair, ensuring that the ligament is securely reattached.
  • Step 5: Repair of Capsular Tears - If there are any tears in the joint capsule, these are also repaired during the procedure to restore the overall stability of the knee joint.

3. Post-Procedure

After the procedure, patients typically undergo a recovery period that may include immobilization of the knee to allow for healing. Physical therapy is often recommended to restore strength and range of motion. The expected recovery time can vary based on the extent of the injury and the specific ligaments involved, but patients are generally advised to follow their surgeon's post-operative care instructions closely to ensure optimal healing and rehabilitation.

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).
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.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
