Summary & Overview
HCPCS L5600: Preparatory Prosthesis for Hip Disarticulation/Hemipelvectomy
HCPCS Level II code L5600 denotes a preparatory prosthesis for patients following hip disarticulation or hemipelvectomy. The code specifies a pylon-style prosthesis without an external cover, fitted with a SACH foot and a laminated socket molded to a patient model. This code is important nationally for documenting prosthetic fabrication and preparatory fitting services for major lower-extremity amputations and influences clinical pathways and device provisioning in prosthetics programs.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise profile of what the code represents, the typical clinical and service settings where it is used, and the types of documentation and device features encoded by the descriptor. The publication provides benchmarks and policy context relevant to national payer coverage and claims processing practices, notes common modifiers associated with prosthetic billing, and situates L5600 among related prosthetic codes for workflow and coding accuracy.
This summary is intended for clinicians, billing professionals, and policy analysts seeking a clear reference for L5600, including the clinical context around hip-disarticulation/hemipelvectomy preparatory prostheses and the payer landscape that commonly adjudicates claims for these devices.

Clinical & Coding Specifications
Clinical Context
A 52-year-old patient with a prior high transfemoral amputation extended to hemipelvectomy-level care following oncologic resection presents to a prosthetics clinic for fabrication of a preparatory external prosthesis. The device described by L5600 is a pylon-style preparatory prosthesis for hip disarticulation/hemipelvectomy with a laminated socket molded to the patient model and a SACH foot, supplied without a cosmetic cover. The typical workflow begins with the prosthetist performing a comprehensive evaluation including residual limb inspection, measurement, and casting or digital modeling. The team confirms functional goals, weight-bearing tolerance, and socket fit requirements. A diagnostic or preparatory prosthesis is fabricated to allow progressive gait training, balance work, and component adjustment prior to delivery of a definitive prosthesis. Follow-up visits address alignment, skin checks, stump-socket interface issues, and progressive mobility training with physical therapy. Typical sites of service include an outpatient prosthetics clinic, specialty orthotics and prosthetics facility, or rehabilitation center. Common payors involved include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
