Summary & Overview
HCPCS L6582: Preparatory Below-Elbow/Wrist Disarticulation Prosthesis
HCPCS Level II code L6582 represents a preparatory, below-elbow prosthetic socket assembly for patients with wrist disarticulation or below-elbow amputation. The device described is a single-wall socket with friction wrist, flexible elbow hinges, figure-of-eight harness, humeral cuff, Bowden cable control, and a USMC-style pylon, direct formed and supplied without a cover. Nationally, this code is significant for outpatient prosthetics services, rehabilitation programs, and payers managing durable medical equipment (DME) benefit design.
Key payers included in the scope are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise presentation of the clinical context for L6582, typical sites of service, and what to expect in coverage considerations. The publication outlines common billing considerations, typical modifiers used with prosthetic DME claims, and how this preparatory device fits into the patient care pathway from fitting through early training and adjustments.
The document provides benchmarks and policy context relevant to national payer programs and DME suppliers, highlights payment and billing patterns for preparatory upper-limb prostheses, and summarizes clinical use cases where L6582 is applicable. Data not available in the input is clearly noted where specific payer rates, taxonomies, or ICD-10 pairings would normally appear.

The item is a single-wall socket with a friction wrist and flexible elbow hinges, equipped with a figure-of-eight harness, humeral cuff, Bowden cable control, a USMC or equal pylon, and is direct formed with no cover.
Service Type: Upper-limb preparatory prosthesis, below-elbow/wrist disarticulation
Typical Site of Service: Outpatient prosthetics clinic or orthotics & prosthetics (O&P) facility
Clinical & Coding Specifications
Clinical Context
A 38-year-old patient presents to a prosthetics clinic following a traumatic below-elbow amputation at the wrist disarticulation level after an industrial accident. The patient requires a preparatory (pre-fabricated or pre-fabricated-derived) socket system to initiate prosthetic training and functional restoration. The device described by billing code L6582 is a single-wall socket with a friction wrist and flexible elbow hinges, controlled by a Bowden cable and figure-of-eight harness with a humeral cuff and pylon. Clinical workflow includes: initial prosthetic evaluation by a certified prosthetist, measurements and casting or digital scan for socket shaping, ordering of components and fabrication of the preparatory unit, fitting and alignment session, training with occupational therapy for donning/doffing, body-powered control (Bowden cable) training, follow-up adjustments for pressure relief or alignment, and periodic progression to a definitive prosthesis once residual limb maturation and patient goals are met. Typical site of service is an outpatient prosthetics/orthotics clinic or hospital-based prosthetics department. The expected patient scenario includes activity-based functional training, durability testing of the friction wrist and flexible elbow hinge, and documentation of functional gains to support transition to a custom definitive prosthesis.
