Official Description

Filleted finger or toe flap, including preparation of recipient site

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 14350 involves the creation of a filleted finger or toe flap, which is a surgical technique used to close large wounds on the hand or foot. This procedure is particularly relevant when there is significant tissue loss or damage that cannot be adequately repaired through primary closure. The term "filleted" refers to the method of dissecting the tissue from the underlying bone while preserving its blood supply, which is crucial for healing. The surgeon makes a precise incision along the middle of the affected finger or toe, allowing for careful dissection of the skin and subcutaneous tissue. This technique ensures that the vascular integrity of the flap is maintained, which is essential for successful grafting and healing. After preparing the recipient site, the flap is rotated into the correct position to cover the wound effectively. The final step involves suturing the wound in layers to promote optimal healing and minimize complications. This procedure is vital in reconstructive surgery, particularly in cases where traditional closure methods are insufficient.

1. Indications

The procedure associated with CPT® Code 14350 is indicated for specific conditions that necessitate the use of a flap for wound closure. These indications include:

  • Large Wounds A significant wound on the finger or toe that cannot be closed by primary intention due to size or tissue loss.
  • Tissue Deficiency Situations where there is inadequate surrounding tissue to facilitate proper closure of the wound.
  • Infection or Necrosis Wounds that are infected or have necrotic tissue, requiring a more complex closure method to ensure healing.

2. Procedure

The procedure for CPT® Code 14350 involves several critical steps to ensure successful flap creation and wound closure. Each step is essential for achieving optimal results.

  • Step 1: Incision The surgeon begins by making a precise incision down the middle of the affected finger or toe. This incision is carefully planned to allow for adequate access to the underlying tissues while minimizing damage to surrounding structures.
  • Step 2: Dissection Following the incision, the surgeon dissects the tissue from the bone. This step is performed with great care to preserve the vascular integrity of the flap, which is crucial for its survival and healing. The dissection allows the flap to be mobilized effectively.
  • Step 3: Preparation of Recipient Site Once the flap is created, the surgeon prepares the recipient site where the flap will be positioned. This preparation may involve cleaning the wound and ensuring that the area is ready for the flap to be sutured in place.
  • Step 4: Flap Rotation The flap is then rotated into the appropriate position to cover the wound adequately. This step is critical to ensure that the flap fits well and that the blood supply is maintained.
  • Step 5: Closure Finally, the surgeon closes the wound in layers using sutures. Layered closure helps to promote healing and reduces the risk of complications such as infection or dehiscence.

3. Post-Procedure

After the completion of the procedure, post-operative care is essential for ensuring proper healing and minimizing complications. Patients are typically monitored for signs of infection or flap failure. Instructions regarding wound care, activity restrictions, and follow-up appointments are provided to ensure optimal recovery. The healing process may vary depending on the individual patient and the extent of the procedure performed. Regular follow-up visits are necessary to assess the healing of the flap and the recipient site, and to make any necessary adjustments to the care plan.

This is a primary code that can be used with these additional add-on codes.

20701 Add-on Code MPFS Status: Active Code APC N Removal of drug-delivery device(s), deep (eg, subfascial) (List separately in addition to code for primary procedure)
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).
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.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
