Summary & Overview
CPT 25929: Stump Remodeling After Transmetacarpal Amputation
CPT code 25929 covers surgical remodeling of the skin and muscle of a stump after transmetacarpal amputation, typically performed to correct improper closure or to relieve pain and contracture. Nationally, this code represents a targeted reconstructive procedure within hand surgery and amputation care, impacting surgical utilization, post-amputation functional outcomes, and payer coverage decisions. The code is relevant to hospital systems, ambulatory surgical centers, hand surgeons, and rehabilitation teams involved in residual limb management.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and typical sites of service, along with benchmarks where available, common billing considerations, and recent policy or coding guidance summaries affecting coverage and documentation. The publication highlights practical billing themes such as appropriate clinical indications, expected care settings, and reporting conventions relevant to surgical revision of transmetacarpal stumps.
This report is organized to deliver immediate operational insights first, followed by clinical and policy detail. It is intended for revenue cycle professionals, surgical providers, and policy analysts seeking a national perspective on coding and utilization for this reconstructive procedure. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 25929 describes surgical remodeling of the skin and muscle structures of a stump following a transmetacarpal amputation (removal of the fingers and a portion of the hand). The procedure addresses problems such as an initially improper closure or pain and contracture within the wound that require revision and reshaping of the residual limb.
-
Service type: Surgical revision of an upper extremity amputation stump (hand-level stump remodeling)
-
Typical site of service: Operating room or ambulatory surgical center, with inpatient setting possible when clinically indicated

Clinical & Coding Specifications
Clinical Context
A 47-year-old manual laborer presents to the hand surgery clinic with chronic pain and poor cosmesis at a transmetacarpal amputation stump performed 9 months earlier after a high-energy crush injury. The patient reports painful contracture of the distal soft tissues, recurrent breakdown of the scar, and difficulty wearing a prosthetic fitting due to a bulbous, poorly contoured stump. Examination shows adherent scar tissue, neuroma formation suspected at the distal edge, and limited soft-tissue mobility with tenderness on palpation. Imaging excludes active infection or bony nonunion.
The clinical workflow includes preoperative assessment (history, focused hand exam, vascular and neurologic evaluation), documentation of prosthetic issues and functional limitation, informed consent, and preoperative optimization. In the operating room the hand surgeon performs scar and neuroma excision, deepening and remodeling of the soft-tissue envelope, flap advancement or local tissue rearrangement, and layered closure to recreate a functional, tapered transmetacarpal stump. Postoperative care includes wound checks, pain control, possible occupational therapy for prosthetic refitting, and documentation of improvement in stump contour and pain. Typical site of service is an ambulatory surgery center or hospital outpatient surgical department. Service type: reconstructive soft-tissue revision of an amputation stump.
