Official Description

Repair, primary, open or percutaneous, ruptured Achilles tendon;

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The Achilles tendon is recognized as the largest tendon in the human body, playing a crucial role in connecting the gastrocnemius and soleus muscles located in the calf to the calcaneus, or heel bone. This tendon is essential for various activities such as walking, running, and jumping, as it facilitates movement and stability. Over time, factors such as aging or a sedentary lifestyle can lead to a weakening and thinning of the Achilles tendon, making it susceptible to injuries. One of the most prevalent injuries associated with this tendon is a complete tear or rupture, which can significantly impair mobility and function. The procedure described by CPT® Code 27650 involves the primary repair of a ruptured Achilles tendon, which can be performed using either an open or percutaneous approach. In the open technique, a longitudinal skin incision is made over the lower leg and ankle, allowing for direct access to the tendon. The ruptured ends of the tendon are then exposed, debrided, and sutured together using heavy nonabsorbable sutures. Alternatively, the percutaneous approach involves making multiple small stab wounds over the posterior aspect of the ankle, through which sutures are passed to repair the tendon. This method minimizes tissue disruption and is often associated with a shorter recovery time. Both techniques aim to restore the integrity of the Achilles tendon, thereby enabling the patient to regain normal function and mobility.

1. Indications

The procedure described by CPT® Code 27650 is indicated for the repair of a ruptured Achilles tendon. This condition typically arises from acute injuries, often resulting in significant pain and loss of function in the affected limb. The following are specific indications for performing this procedure:

  • Complete Achilles Tendon Rupture A complete tear of the Achilles tendon, which may occur due to sudden forceful movements or trauma.
  • Severe Pain and Dysfunction Patients experiencing severe pain and inability to bear weight or perform normal activities due to the rupture.
  • Failure of Conservative Treatment Cases where non-surgical management, such as rest, physical therapy, or bracing, has not resulted in adequate healing or improvement.

2. Procedure

The procedure for repairing a ruptured Achilles tendon as described by CPT® Code 27650 can be performed using either an open or percutaneous approach. Each method involves specific steps to ensure effective repair of the tendon.

  • Open Approach In the open technique, a posteromedial longitudinal skin incision is made over the lower leg and ankle region. This incision allows the surgeon to access the underlying structures. The subcutaneous tissue is carefully dissected to expose the paratenon, which is then divided longitudinally. Once the paratenon is opened, the ruptured ends of the Achilles tendon are revealed. The surgeon debrides the damaged tissue from the ruptured ends to promote healing and then approximates the tendon ends. Heavy nonabsorbable sutures are used to securely repair the tendon, ensuring that it can withstand the stresses of movement during the recovery process.
  • Percutaneous Approach In the percutaneous method, the patient's foot is positioned in maximal equinus to facilitate access to the tendon. Multiple stab wounds are made over the posterior aspect of the ankle, allowing for the insertion of sutures through the distal and proximal ends of the Achilles tendon. After the sutures are passed through the tendon, they are cut, tied off, and pushed into the subcutaneous tissue to minimize scarring. The overlying soft tissues and skin are then repaired, and a short leg nonweight-bearing cast is applied to immobilize the area and support healing.

3. Post-Procedure

After the repair of the ruptured Achilles tendon, whether performed via the open or percutaneous approach, post-procedure care is essential for optimal recovery. Patients are typically placed in a short leg nonweight-bearing cast to immobilize the ankle and prevent movement that could jeopardize the repair. The duration of casting may vary based on the surgeon's protocol and the patient's healing progress. Rehabilitation often begins with gentle range-of-motion exercises, gradually progressing to strengthening activities as healing allows. Follow-up appointments are crucial to monitor the healing process and to make any necessary adjustments to the rehabilitation plan. Patients are advised to avoid putting weight on the affected leg until cleared by their healthcare provider to ensure proper healing and to minimize the risk of 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.
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).
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.)
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.)
