Summary & Overview
HCPCS L3924: Hand Finger Orthosis Without Joints, Prefabricated
HCPCS Level II code L3924 denotes a prefabricated, off-the-shelf hand finger orthosis without joints, intended to provide static support or positioning for the hand and fingers. As a common durable medical equipment (DME) orthotic, this code matters nationally because it guides reimbursement for widely used devices in post-injury, postoperative, and chronic hand condition management. Proper coding affects patient access to orthotic support and standardization of billing across outpatient and ambulatory care settings.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for use of L3924, typical sites where the device is provided, and what to expect in payer coverage patterns. The publication covers benchmarks for utilization and reimbursement structures, summaries of relevant payer policy features, and coding considerations for suppliers and billing teams.
This summary provides concise guidance on where L3924 fits within orthotic services: the device type, expected clinical indications for static support, and how it is delivered in outpatient and supplier settings. Data not available in the input will be identified within detailed sections.

Clinical & Coding Specifications
Clinical Context
A 52-year-old right-handed administrative assistant presents to an outpatient orthotics clinic after sustaining a work-related hyperextension injury to the ring and small fingers of the dominant hand. The patient reports localized pain, swelling, and difficulty performing fine motor tasks. The treating occupational therapist and hand surgeon assess for joint stability and range of motion and determine a prefabricated, non-jointed digital orthosis is appropriate to immobilize the fingers and protect soft tissue while allowing limited hand function.
The typical clinical workflow: the hand surgeon documents the diagnosis and medical necessity, writes an order for a prefabricated hand/finger orthosis L3924, and specifies laterality. An occupational therapist or certified orthotist performs a brief fitting and adjustment in the clinic, confirms fit and skin protection with a soft interface and straps, provides patient education on wear time and skin checks, and documents the fitting session. Follow-up visit is scheduled within 1–2 weeks to assess healing, fit, and need for continued immobilization or progression to a custom device.
