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.
