Official Description

Carpectomy; 1 bone

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The carpus, commonly referred to as the wrist joint, is composed of eight small bones arranged in two rows, with four bones in each row. The proximal row consists of the pisiform, triquetrum, lunate, and scaphoid (also known as the navicular) bones, while the distal row includes the hamate, capitate, trapezoid, and trapezium bones. The procedure described by CPT® Code 25210 involves the excision of a single carpal bone. This surgical intervention is typically indicated when there is a need to remove a bone due to various conditions affecting the wrist. During the procedure, a longitudinal incision is made on the dorsal aspect of the wrist, directly over the carpal bone designated for excision. To facilitate access, traction is applied to the fingers, allowing for better exposure of the carpal bone while ensuring that surrounding ligaments are preserved. A rongeur, a surgical instrument designed for cutting bone, is utilized to remove the middle portion of the targeted bone, which results in the bone collapsing inward. Subsequently, the remaining proximal and distal portions of the bone are carefully excised. After the excision is complete, the incision is meticulously closed in layers, and the wrist is immobilized in a cast to promote healing and stability post-surgery.

1. Indications

The procedure described by CPT® Code 25210 is indicated for various conditions affecting the wrist that necessitate the removal of a single carpal bone. These indications may include:

  • Chronic Pain Persistent pain in the wrist that may be due to degenerative changes or trauma affecting the carpal bone.
  • Bone Fracture A fracture of the carpal bone that has not healed properly or is causing significant dysfunction.
  • Osteoarthritis Degenerative joint disease affecting the carpal bone, leading to pain and reduced mobility.
  • Instability Wrist instability resulting from conditions such as scapholunate dissociation or other ligamentous injuries.

2. Procedure

The procedure for CPT® Code 25210 involves several key steps to ensure the successful excision of the carpal bone. Each step is critical for achieving the desired outcome while minimizing complications.

  • Step 1: Incision A longitudinal incision is made on the dorsal aspect of the wrist, directly over the carpal bone that is to be excised. This incision provides access to the underlying structures and is carefully planned to minimize damage to surrounding tissues.
  • Step 2: Application of Traction Traction is applied to the fingers to facilitate better exposure of the carpal bone. This step is essential for ensuring that the surgical field is adequately visualized and that the bone can be accessed without obstruction.
  • Step 3: Exposure of the Carpal Bone The carpal bone is exposed while taking care to preserve the surrounding ligaments. This preservation is crucial to maintain wrist stability and function post-surgery.
  • Step 4: Bone Excision A rongeur is utilized to excise the middle portion of the carpal bone. This action causes the bone to collapse inward, allowing for easier removal of the remaining portions. The surgeon then carefully excises the proximal and distal aspects of the bone to complete the removal.
  • Step 5: Closure After the excision is complete, the incision is closed in layers. This layered closure technique helps to promote proper healing and reduces the risk of complications such as infection or dehiscence.
  • Step 6: Immobilization Finally, the wrist is immobilized in a cast to provide support and stability during the healing process. This immobilization is critical to ensure that the surgical site remains undisturbed as it heals.

3. Post-Procedure

Post-procedure care following a carpectomy involves monitoring the surgical site for signs of infection and ensuring that the wrist remains immobilized as directed. Patients are typically advised to keep the cast dry and to avoid any activities that may stress the wrist during the initial recovery phase. Follow-up appointments are essential to assess healing and to determine when physical therapy may be appropriate to restore function and strength to the wrist. Pain management strategies may also be discussed to ensure patient comfort during the recovery process.

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.
RT Right side (used to identify procedures performed on the right side of the body)
LT Left side (used to identify procedures performed on the left side of the body)
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).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
SG Ambulatory surgical center (asc) facility service
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main 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).
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.
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.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
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.)
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).
