Official Description

Tenotomy, open, tendon flexor; toe, single tendon (separate procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 28232 refers to an open tenotomy of a single flexor tendon in the toe, classified as a separate procedure. A tenotomy is a surgical procedure that involves the incision of a tendon, which is a fibrous connective tissue that attaches muscle to bone. In this case, the focus is on the flexor tendon, which is responsible for bending the toe. The procedure begins with making an incision in the skin over the affected area of the foot or toe, allowing access to the underlying soft tissues. Once the incision is made, the surgeon carefully dissects the soft tissues to expose the flexor tendon that requires treatment. The tendon is then incised, effectively severing or releasing it to alleviate any tension or restriction that may be causing discomfort or functional impairment. To manage any bleeding that occurs during the procedure, electrocautery is utilized, which is a technique that uses electrical current to coagulate blood vessels. After the tendon has been successfully incised, the surgeon closes the operative wound in layers to promote proper healing and minimize complications. It is important to note that CPT® Code 28232 is specifically designated for the open tenotomy of a single toe tendon, distinguishing it from other related procedures, such as the open tenotomy of one or more flexor tendons of the foot, which is coded under CPT® Code 28230.

1. Indications

The open tenotomy of a single flexor tendon in the toe, as described by CPT® Code 28232, is indicated for specific conditions that affect the function of the toe. These indications may include:

  • Flexor tendon contracture - A condition where the flexor tendon is shortened, leading to an inability to fully extend the toe.
  • Toe deformities - Such as hammertoe or claw toe, where the toe is abnormally bent due to imbalances in tendon tension.
  • Chronic pain - Resulting from tendon tightness or injury that affects mobility and quality of life.

2. Procedure

The procedure for an open tenotomy of a single flexor tendon in the toe involves several critical steps, which are outlined as follows:

  • Step 1: Incision - The surgeon begins by making a precise incision in the skin over the area of the toe where the flexor tendon is located. This incision is carefully placed to minimize damage to surrounding tissues and to provide adequate access to the tendon.
  • Step 2: Dissection - Following the incision, the surgeon meticulously dissects the soft tissues surrounding the tendon. This step is crucial for exposing the tendon without causing unnecessary trauma to adjacent structures.
  • Step 3: Tendon Exposure - Once the soft tissues are adequately dissected, the flexor tendon is fully exposed. This allows the surgeon to visualize the tendon and assess the extent of the condition that necessitates the tenotomy.
  • Step 4: Incision of the Tendon - The surgeon then proceeds to incise the flexor tendon. This involves severing or releasing the tendon to alleviate any tension or restriction that may be present, thereby addressing the underlying issue.
  • Step 5: Hemostasis - During the procedure, any bleeding that occurs is controlled using electrocautery. This technique helps to coagulate blood vessels and minimize blood loss, ensuring a clearer surgical field.
  • Step 6: Wound Closure - After the tendon has been incised and the procedure is complete, the surgeon closes the operative wound in layers. This layered closure technique is important for promoting optimal healing and reducing the risk of complications such as infection.

3. Post-Procedure

After the completion of the open tenotomy procedure, patients can expect specific post-operative care and recovery considerations. The surgical site will require monitoring for signs of infection, and patients may be advised to keep the area clean and dry. Pain management may be necessary, and the physician may prescribe analgesics to alleviate discomfort. Patients are typically instructed on how to care for the incision site and may be advised to limit weight-bearing activities on the affected foot for a specified period to promote healing. Follow-up appointments will be necessary to assess the healing process and to determine when physical therapy or rehabilitation may be appropriate to restore function and strength to the toe.

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.
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).

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.
LT Left side (used to identify procedures performed on the left side of the body)
SG Ambulatory surgical center (asc) facility service
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.
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.
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).
