Summary & Overview
HCPCS L2134: KAFO for Femoral Fracture, Semi-Rigid Prefabricated
HCPCS Level II code L2134 designates a prefabricated, semi-rigid knee-ankle-foot orthosis (KAFO) intended as a femoral fracture cast orthosis and includes fitting and adjustment. Nationally, this code matters because it standardizes billing for a commonly used orthotic device that supports femoral fracture management and post-injury immobilization, influencing coverage, device availability, and clinical care pathways.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of what L2134 represents clinically and operationally, payer coverage considerations, and typical sites of service. The publication outlines benchmark elements such as common billing patterns and service-line classification for orthotics, summarizes relevant policy and coding considerations affecting reimbursement and documentation, and situates the device within typical clinical workflows for fracture management.
The report provides practical context for coding staff, billing managers, and orthotics teams: a clear definition of the product and service type, expectations for where fitting and adjustments occur, and an overview of topics to review with payers and clinical teams. Data not available in the input is noted where applicable.
Billing Code Overview
HCPCS Level II code L2134 describes a KAFO, fracture orthosis, femoral fracture cast orthosis, semi-rigid, prefabricated, includes fitting and adjustment. This item is a prefabricated knee-ankle-foot orthosis (KAFO) designed to manage femoral fractures by providing semi-rigid immobilization and support. The service type is orthotic device provision and fitting, and the typical site of service is outpatient orthotics/prosthetics clinics or hospital outpatient departments, where prefabricated orthoses are selected, fitted, and adjusted for patients.
Clinical & Coding Specifications
Clinical Context
A 46-year-old male presents to an orthopedic clinic after sustaining a mid-shaft femoral fracture in a motor vehicle collision. The orthopedist evaluates the patient in clinic, orders radiographs to confirm fracture alignment, and elects nonoperative management using a prefabricated semi-rigid femoral fracture cast orthosis (KAFO-type fracture orthosis) to immobilize the femur while soft tissues recover and healing begins. The device is selected, sized, fitted, and adjusted in the outpatient setting; the visit includes patient education on wear time, skin inspection, and activity restrictions. Follow-up visits at 1–2 weeks and 6 weeks include orthosis adjustment, wound/skin checks if applicable, and repeat imaging to assess healing. Typical sites of service are outpatient orthopedic clinics, ambulatory surgery centers for device application if performed in that setting, and inpatient hospital wards if device application occurs during hospitalization. The service described by L2134 includes the prefabricated semi-rigid femoral fracture cast orthosis and global fitting and adjustment performed by an appropriate orthotics provider or orthopedic clinician.
