Summary & Overview
CPT 27596: Femoral Stump Shortening for Prosthetic Fitting
CPT code 27596 covers surgical shortening or revision of an already amputated femur when the residual stump is nonhealing or unsuited for prosthetic fitting. The procedure is clinically significant because stump integrity and length directly affect wound healing, prosthetic fitting, mobility outcomes, and prosthesis candidacy. Nationally, appropriate coding for femoral stump revisions affects surgical quality reporting, payment determinations, and continuity of care for amputation patients. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what CPT code 27596 represents, the typical clinical context and sites of service, and the primary payer landscape. The publication outlines common billing modifiers associated with complex surgical services, summarizes where to expect coverage considerations, and highlights clinical factors that drive use of this code, including nonhealing stumps and prosthetic fitting needs. It also explains what information is not available in the input and points readers to where to look for payer-specific reimbursement policies. This national-level summary is intended to inform coding accuracy, administrative planning, and clinical documentation for surgical teams and billing staff involved in lower-extremity amputation care.
Billing Code Overview
CPT code 27596 describes a surgical procedure to remove additional length from an already amputated femur (thigh) bone. This is performed when a residual femoral stump is nonhealing or is not appropriate in its current form to fit a prosthesis.
-
Service type: Surgical amputation revision (femoral stump shortening)
-
Typical site of service: Inpatient or outpatient surgical setting, depending on clinical needs and anesthesia requirements

Clinical & Coding Specifications
Clinical Context
A 62-year-old male with a transfemoral (above-knee) amputation from prior traumatic injury presents to the orthopedic surgery clinic with persistent stump pain, wound drainage, and failure of the distal femoral residual limb to heal or to allow prosthetic fitting. Conservative measures including wound care and antibiotics have failed. The surgical team plans a revision amputation to shorten the femoral residual limb to healthy tissue, reshape the bone and soft tissues, and create a stump suitable for prosthetic fitting and pain control. The procedure is performed in an operating room under general or regional anesthesia with perioperative antibiotics. Typical workflow includes preoperative evaluation and imaging (plain radiographs of the residual femur), intraoperative removal of scar tissue and nonviable bone, femoral shortening and soft-tissue revision, hemostasis, layered closure, and postoperative dressing and prosthetic consultation. Usual sites of service are the hospital operating room or an ambulatory surgical center depending on patient comorbidities and complexity. Postoperative care includes pain management, stump care instructions, wound checks, and coordination with prosthetics and rehabilitation services for eventual prosthesis fitting.
