Summary & Overview
HCPCS L2038: Knee-Ankle-Foot Orthosis, Full Plastic, Custom Fabricated
HCPCS Level II code L2038 denotes a custom-fabricated full-plastic knee-ankle-foot orthosis (KAFO), with or without a free-motion knee and featuring a multi-axis ankle. This orthosis provides comprehensive support for patients with significant lower-extremity instability, neuromuscular weakness, or deformity and is commonly used to improve alignment, mobility, and safety. Nationally, KAFOs like L2038 are significant due to their clinical impact on mobility and their role in durable medical equipment and orthotics expenditures.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise profile of the device and coding context, along with benchmarks and policy-relevant observations where available. The publication outlines expected sites of service, common billing considerations, and related HCPCS coding context. It also summarizes payer coverage patterns and reimbursement considerations at a national level.
This summary equips clinicians, billing professionals, and policy analysts with the essential coding definition, clinical use case, and the types of payer policy issues to expect when managing claims for custom-fabricated KAFOs under L2038.

Clinical & Coding Specifications
Clinical Context
A 56-year-old patient with post-polio residual weakness and progressive right knee instability is referred for a custom knee-ankle-foot orthosis. The patient reports frequent trips and recurrent falls due to knee buckling and an unstable multi-planar ankle. A physical medicine and rehabilitation physician evaluates gait, joint range of motion, and skin integrity. A certified orthotist performs a cast or 3D scan of the lower limb, documents measurements, and orders a custom-fabricated full-plastic knee-ankle-foot orthosis with a multi-axis ankle and optional free-motion knee to restore alignment and provide stance stability. The orthosis is manufactured in a facility and later delivered in an outpatient orthotics clinic; a fit visit confirms alignment, in-situ function, and patient education on donning, doffing, skin checks, and durable medical equipment care. Follow-up visits at two and six weeks address adjustments and functional outcomes.
