Summary & Overview
HCPCS L3984: Upper Extremity Wrist Fracture Orthosis, Prefabricated
HCPCS Level II code L3984 denotes a prefabricated wrist orthosis supplied for upper extremity fractures, including professional fitting and adjustment. The code reflects a common durable medical equipment (DME) intervention used to immobilize the wrist after fracture, reducing pain and supporting healing. Nationally, prefabricated orthoses are frequently used because they allow rapid provision and lower upfront cost compared with custom devices, while still enabling clinician-directed fit and adjustment.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for L3984, typical sites of service, and the types of documentation and coding circumstances that commonly accompany DME orthoses. The publication outlines pricing and coverage benchmark themes, common modifier usage patterns where available, and notable policy features that affect authorization and reimbursement for prefabricated wrist fracture orthoses.
This summary is intended for billing managers, DME suppliers, clinicians, and policy analysts seeking an authoritative reference on scope and practical considerations for HCPCS Level II code L3984. Data not available in the input is noted where applicable; the content focuses on nationally relevant guidance and coding context rather than state-specific rules.
Billing Code Overview

This item is a prefabricated wrist orthosis provided to support and immobilize the wrist following an upper extremity fracture. The service type is durable medical equipment supplying an orthotic device with included fitting and adjustment. The typical site of service is outpatient clinics, orthotics/prosthetics shops, ambulatory surgery centers (for post-procedure immobilization), and other ambulatory care settings where prefabricated orthoses are dispensed and fitted.
Clinical & Coding Specifications
Clinical Context
A 42-year-old right-hand–dominant patient presents to an outpatient orthopedics clinic after sustaining a distal radius fracture on the dominant wrist from a fall onto an outstretched hand. Radiographs confirm a nondisplaced distal radius fracture with acceptable alignment managed nonoperatively. The clinician determines a prefabricated wrist fracture orthosis is appropriate to immobilize the wrist, provide support during early healing, and allow limited functional use.
During the clinical workflow the orthotist or trained clinic staff selects a prefabricated upper extremity fracture orthosis described by billing code L3984. The device is fitted and adjusted for proper fit, straps, and padding. The provider documents the indication, device model, fitting details, patient tolerance, and care instructions. Follow-up visits include reassessment of fit, monitoring for skin issues, and progression of activity as healing permits. If clinical status changes (increased swelling, cast intolerance, need for custom device), the treatment plan is revised and documented.
