Summary & Overview
HCPCS L5250: Hip Disarticulation Prosthesis with Molded Socket and Single-Axis Knee
HCPCS Level II code L5250 identifies a custom prosthetic assembly for patients with hip disarticulation (Canadian type) that includes a molded socket, hip joint, single-axis constant-friction knee, shin, and SACH foot. This code matters nationally because it defines coverage and billing for a high-cost, highly customized prosthetic service that supports mobility and functional independence for patients with major lower-limb loss.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of how L5250 is used in practice, typical sites of service, and the clinical context surrounding hip-disarticulation prostheses. The publication summarizes payment and coverage considerations across major national payers, highlights common billing and documentation elements associated with prosthetic device claims, and outlines areas where policy updates or utilization patterns have practical implications for providers and suppliers.
The report provides benchmarks for utilization and reimbursement where available, explains typical care pathways from fabrication to fitting and follow-up, and clarifies the service components represented by the code. Data not available in the input will be noted explicitly in applicable sections.
Billing Code Overview
HCPCS Level II code L5250 describes a prosthetic lower-limb assembly for a patient with a hip disarticulation (Canadian type). The full description specifies a molded socket with a hip joint, a single axis constant friction knee, a shin, and a sach foot, indicating a custom-molded transfemoral/hip-disarticulation prosthesis.
Service Type: Prosthetic device fabrication and fitting for hip disarticulation
Typical Site of Service: Prosthetics and orthotics clinic, prosthetic fabrication lab, or outpatient rehabilitation facility
Clinical & Coding Specifications
Clinical Context
A 58-year-old male with a history of chronic, nonhealing proximal femoral osteomyelitis following multiple failed limb-sparing surgeries presents with persistent deep infection, recurrent sepsis, and nonviable soft tissue over the hip girdle. After multidisciplinary assessment including infectious disease and rehabilitation medicine, the decision is made for hip disarticulation with provision of a prosthesis described by HCPCS Level II code L5250 (Canadian-type molded socket, hip joint, single-axis constant friction knee, shin, SACH foot). The clinical workflow includes preoperative evaluation (medical clearance, vascular and infectious workup), preprosthetic planning (socket design and casting, measurements), the surgical procedure (hip disarticulation), inpatient postoperative care (wound management, pain control, early mobility training), prosthetic fitting and alignment in the prosthetics clinic, and progressive rehabilitation with a physical therapist and prosthetist to achieve safe transfers, wheelchair mobility, and, when appropriate, gait training using the described prosthesis.
