Official Description

Wedge excision of skin of nail fold (eg, for ingrown toenail)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A wedge excision of the skin of the nail fold is a surgical procedure primarily aimed at treating an ingrown toenail, a condition where the edge of the toenail grows into the surrounding skin, often leading to pain, swelling, and infection. This procedure is particularly indicated for patients experiencing chronic infections that result in diseased tissue along the nail fold. During the wedge excision, a precise incision is made at the nail fold, allowing for the removal of a wedge-shaped section of the affected tissue. This excision helps alleviate the pressure and irritation caused by the ingrown toenail. After the excision, the wound is intentionally left open to heal by secondary intention, which means that the body will naturally close the wound over time without the need for sutures. To promote healing and prevent infection, antibiotic ointment is applied to the area, followed by a protective dressing. This approach not only addresses the immediate issue of the ingrown toenail but also facilitates a more natural healing process for the surrounding skin.

1. Indications

The wedge excision of the skin of the nail fold is indicated for the following conditions:

  • Ingrown Toenail This procedure is performed to treat an ingrown toenail, where the toenail grows into the surrounding skin, causing pain and discomfort.
  • Chronic Infection It is indicated for patients with chronic infections that result in diseased tissue along the nail fold, necessitating surgical intervention to remove the affected tissue.

2. Procedure

The wedge excision procedure involves several key steps that ensure effective treatment of the ingrown toenail.

  • Step 1: Preparation The patient is positioned comfortably, and the affected area is cleaned and sterilized to minimize the risk of infection during the procedure.
  • Step 2: Anesthesia Local anesthesia is administered to numb the area around the nail fold, ensuring that the patient does not experience pain during the excision.
  • Step 3: Incision A precise incision is made at the nail fold, allowing access to the diseased tissue that is causing the ingrown toenail.
  • Step 4: Wedge Excision A wedge-shaped section of the diseased tissue is carefully excised. This step is crucial as it removes the source of irritation and infection.
  • Step 5: Wound Management After the excision, the wound is left open to heal by secondary intention, which allows the body to close the wound naturally over time.
  • Step 6: Dressing Finally, antibiotic ointment is applied to the excised area, followed by a dressing to protect the wound and promote healing.

3. Post-Procedure

Post-procedure care involves monitoring the wound for signs of infection and ensuring proper healing. Patients are typically advised to keep the area clean and dry, change the dressing as needed, and apply antibiotic ointment as directed. Follow-up appointments may be scheduled to assess the healing process and address any complications that may arise. Patients should also be informed about signs of infection, such as increased redness, swelling, or discharge, and instructed to seek medical attention if these occur.

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).

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.)
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.

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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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.
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.)
