HCPCS Level II code L4110 denotes replacement of a leather cuff for a KAFO-AFO device at the calf or distal thigh. This orthotic component code is used when a worn or damaged leather cuff on combined knee-ankle-foot/ankle-foot orthoses is replaced to restore fit and function. Nationally, orthotic component codes like L4110 are relevant to durable medical equipment suppliers, orthotists, outpatient rehabilitation providers, and payers managing prosthetic and orthotic benefits.

Clinical & Coding Specifications
Clinical Context
A 56-year-old patient with long-standing peripheral neuropathy and foot drop presents to an orthotics clinic for maintenance of a custom KAFO-AFO fitted with a leather calf or distal thigh cuff. The device has intact structural components but the leather cuff shows wear, cracking, and loss of padding leading to skin irritation and reduced suspension. An orthotist evaluates the limb, documents measurements, inspects the existing orthosis, and determines that replacing the leather cuff (calf or distal thigh) will restore fit and comfort without replacing the entire orthosis. The typical clinical workflow includes face-to-face assessment, removal of the worn cuff, fabrication or selection of a replacement leather cuff component, attachment and alignment to the existing KAFO-AFO, patient gait assessment, and documentation of medical necessity and functional improvement. Usual sites of service are outpatient orthotics clinics, durable medical equipment provider facilities, or hospital-based orthotics departments. Typical payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
