Official Description

Amputation, finger or thumb, primary or secondary, any joint or phalanx, single, including neurectomies; with direct closure

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

An amputation of the finger or thumb, as described by CPT® Code 26951, involves the surgical removal of all or part of the digit due to various medical conditions such as severe trauma, infection, or malignant tumors. This procedure can be performed at different anatomical levels, specifically at the interphalangeal (IP) joints, which are the joints between the phalanges, or at the metacarpophalangeal (MCP) joint, which connects the finger to the hand. The amputation may also occur through one of the phalanges, the long bones in the fingers. The surgical process begins with a skin incision made at the predetermined level for the amputation. Following the incision, the surrounding soft tissues are carefully dissected to expose the joint or phalanx that is to be removed. During the procedure, tendons may need to be detached or divided and subsequently reattached to the remaining bone to maintain functionality of the adjacent structures. Additionally, digital nerves are addressed through a technique known as traction neurectomy, where the nerve ends are longitudinally distracted and transected, allowing them to retract proximally. This technique minimizes the risk of neuroma formation by ensuring that the nerve ends are positioned away from the amputation site. Blood vessels are also managed by being suture ligated and divided or cauterized to control bleeding. If the amputation occurs at a joint, the joint structures are dissected, and the finger is completely severed, while the articular cartilage is preserved on the remaining bone to cushion it. In cases where the amputation is through a phalanx, a small bone saw is utilized to cut the bone, and the end is smoothed to prevent sharp edges. Finally, the soft tissues overlying the amputation site are closed in layers to promote healing and minimize complications.

1. Indications

The procedure described by CPT® Code 26951 is indicated for the following conditions:

  • Severe Trauma: Significant injury to the finger or thumb that cannot be repaired or salvaged.
  • Infection: Presence of an infection that compromises the integrity of the digit and poses a risk to the patient's health.
  • Malignant Tumor: The presence of cancerous growths in the finger or thumb that necessitate removal to prevent further spread of the disease.

2. Procedure

The procedure for amputation of the finger or thumb involves several critical steps:

  • Step 1: Incision A skin incision is made at the designated level for the amputation, which is determined based on the specific condition affecting the digit.
  • Step 2: Dissection of Soft Tissues The surgeon carefully dissects the surrounding soft tissues to expose the underlying joint or phalanx that is to be amputated.
  • Step 3: Management of Tendons Tendons that are attached to the digit may need to be detached or divided. If necessary, they are reattached to the remaining bone to preserve function in adjacent areas.
  • Step 4: Neurectomy Digital nerves are longitudinally distracted distally and transected using a traction neurectomy technique, allowing the nerve ends to retract proximally to minimize the risk of neuroma formation.
  • Step 5: Vascular Control Blood vessels are managed by being suture ligated and divided or cauterized to control any bleeding during the procedure.
  • Step 6: Joint Dissection (if applicable) If the amputation is performed at the joint, the joint structures are dissected, and the finger is completely severed, ensuring that the articular cartilage remains on the remaining bone.
  • Step 7: Bone Cutting (if applicable) In cases where the amputation is through one of the phalanges, a small bone saw is used to cut the bone at the desired level, and the bone end is smoothed using a rongeur or file.
  • Step 8: Closure The overlying soft tissues are then closed in layers to promote healing and minimize complications.

3. Post-Procedure

Post-procedure care following an amputation of the finger or thumb includes monitoring the surgical site for signs of infection, managing pain, and ensuring proper wound healing. Patients may require follow-up visits to assess the healing process and to address any complications that may arise. Rehabilitation may also be necessary to help the patient adapt to the loss of the digit and to regain functionality in the hand. The specific recovery timeline can vary based on the individual patient's health and the extent of the amputation.

X4 Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period
F8 Right hand, fourth digit
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.
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).
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.
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.
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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 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.)
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).
