Summary & Overview
HCPCS L5824: Endoskeletal Knee-Shin Single-Axis with Fluid Swing Control
HCPCS Level II code L5824 denotes an addition to an endoskeletal knee-shin orthotic system: a single-axis knee joint with fluid swing phase control. The code identifies a specific orthotic component designed to modulate knee motion during swing, improving gait dynamics for patients who use lower-limb orthoses. Nationally, this code matters because precise coding influences coverage decisions for durable medical equipment and orthotic fittings and can affect patient access to advanced knee-shin components.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise guidance on the clinical role of the device, typical service settings, and the types of information payers commonly evaluate for coverage and billing. The publication summarizes benchmarks and policy considerations relevant to orthotic component additions, clarifies typical documentation expectations, and situates L5824 within prosthetics and orthotics service lines.
This summary is intended to give clinicians, billing professionals, and policy analysts a clear, national-level view of what L5824 represents, why it is used clinically, and which major payers are commonly engaged when claims for this orthotic addition are submitted. Data not available in the input will be noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 54-year-old male transtibial amputee presents to a prosthetics clinic for upgrade of his endoskeletal knee-shin component. The patient ambulates independently with a single-axis prosthetic knee but reports instability during the swing phase and increased energy expenditure on uneven terrain. The prosthetist evaluates gait, socket fit, and alignment in a dedicated outpatient prosthetics workshop. A trial demonstrates improved cadence and smoother limb advancement when a single-axis knee featuring fluid swing phase control is fitted. The addition is ordered to the existing endoskeletal knee-shin system to provide hydraulic damping during swing phase and improve gait symmetry. The clinical workflow includes prosthetist assessment, measurement and ordering of the L5824 component, fabrication and bench assembly, socket/component alignment and dynamic trial in the clinic, final adjustments, patient training in gait and safety, and documentation of functional outcomes and justification for the upgraded component.
