Official Description

Tenotomy, percutaneous, Achilles tendon (separate procedure); general anesthesia

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A percutaneous tenotomy of the Achilles tendon, designated by CPT® Code 27606, is a surgical procedure aimed at addressing shortening or contracture of the Achilles tendon. This condition is often associated with clubfoot deformity, where the tendon becomes tight and restricts normal foot movement. The procedure involves making a small stab incision at the predetermined site on the Achilles tendon, allowing for direct access to the tendon without the need for extensive surgical exposure. Once the incision is made, the tendon is carefully incised to relieve the tension. In many cases, a Z-plasty incision technique is employed, which facilitates the lengthening of the tendon. After the tendon has been incised, the stab incision is typically closed using sutures or Steri-Strips to promote healing. Following the procedure, the foot is placed in a cast to maintain the newly achieved length of the tendon and to support the healing process. It is important to note that this specific code is utilized when the procedure is performed under general anesthesia, distinguishing it from similar procedures that may be conducted under local anesthesia, such as CPT® Code 27605.

1. Indications

The percutaneous tenotomy of the Achilles tendon, coded as CPT® 27606, is indicated for specific conditions related to the Achilles tendon. The primary indications include:

  • Shortening of the Achilles tendon - This condition can lead to limited mobility and discomfort, necessitating surgical intervention to restore normal function.
  • Contracture of the Achilles tendon - A contracture can result in a tightness of the tendon, which may cause deformities such as clubfoot, requiring correction through tenotomy.
  • Clubfoot deformity - This congenital condition often involves a shortening of the Achilles tendon, and tenotomy is a common surgical approach to correct the foot's position and improve mobility.

2. Procedure

The procedure for a percutaneous tenotomy of the Achilles tendon involves several key steps, which are detailed as follows:

  • Step 1: Anesthesia Administration - The procedure begins with the administration of general anesthesia to ensure the patient is completely unconscious and pain-free during the surgery.
  • Step 2: Incision Creation - A small stab incision is made over the Achilles tendon at the site where the tenotomy is planned. This incision is minimal, allowing for less tissue disruption and quicker recovery.
  • Step 3: Tendon Incision - Once the incision is made, the surgeon carefully incises the Achilles tendon. This step is crucial as it relieves the tension caused by shortening or contracture.
  • Step 4: Z-Plasty Technique - In many cases, a Z-plasty incision technique is utilized to lengthen the tendon effectively. This technique involves creating a zigzag pattern that allows for greater lengthening of the tendon.
  • Step 5: Wound Closure - After the tendon has been incised, the stab incision is closed using sutures or Steri-Strips. This closure method helps to promote healing while minimizing scarring.
  • Step 6: Post-Procedure Casting - Following the closure of the incision, the foot is placed in a cast. This cast is essential for maintaining the length achieved in the tendon and supporting the healing process.

3. Post-Procedure

After the percutaneous tenotomy of the Achilles tendon, patients can expect specific post-procedure care and considerations. The foot will remain in a cast for a designated period to ensure that the tendon heals properly and maintains its new length. Patients are typically advised to limit weight-bearing activities during the initial recovery phase to prevent stress on the healing tendon. Follow-up appointments are essential to monitor the healing process and to assess the need for physical therapy, which may be recommended to restore strength and mobility in the affected foot. It is important for patients to adhere to their healthcare provider's instructions regarding care and activity restrictions to ensure optimal recovery outcomes.

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).
LT Left side (used to identify procedures performed on the left side of the body)
RT Right side (used to identify procedures performed on the right side of the body)
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.
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
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).

(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).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
