Summary & Overview
HCPCS L3981: Humeral Fracture Orthosis, Prefabricated
HCPCS Level II code L3981 identifies a prefabricated upper extremity fracture orthosis for the humerus featuring a shoulder cap design, optional joints, and an integrated forearm section. The code covers supply of the orthosis plus fitting and adjustments. Nationally, such orthoses are a common component of nonoperative fracture management and postoperative immobilization, with implications for durable medical equipment policies, reimbursement consistency, and clinical care pathways across payers.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Readers will find a concise overview of coverage characteristics and payment considerations for prefabricated humeral orthoses, typical sites of service where the device is dispensed and fitted, and the clinical contexts in which the device is used. The publication outlines pricing and billing benchmarks where available, common billing modifiers and service-line considerations, and notes policy elements that affect prior authorization and claim adjudication for orthotic supplies.
The report is designed for clinicians, durable medical equipment suppliers, coding and billing professionals, and policy analysts seeking a succinct national perspective on coding, site-of-service expectations, and administrative factors that influence delivery and reimbursement of humeral fracture orthoses under L3981. Data not available in the input are noted where relevant.

Clinical & Coding Specifications
Clinical Context
A 52-year-old male presents to an orthopedic clinic after a fall onto his outstretched arm. Radiographs confirm a displaced mid-shaft humeral fracture with shoulder involvement. The orthopedist determines the patient is an appropriate candidate for nonoperative management and orders an upper extremity fracture orthosis to immobilize the humerus and shoulder complex. The orthotist performs a face-to-face fitting visit in the outpatient orthopedic clinic, selects a prefabricated humeral fracture orthosis with shoulder cap design and a forearm section (L3981), adjusts straps and any soft interface, and documents measurements, patient education on donning/doffing, and functional restrictions. Follow-up visits at 1–2 weeks and 6 weeks include adjustments, assessment of skin integrity, and documentation of progress toward fracture union. Typical sites of service include outpatient orthopedic clinics, durable medical equipment provider offices, and hospital outpatient departments. The appliance is supplied with fitting and adjustments included in the service, and may be billed when criteria for a prefabricated humeral fracture orthosis are met.
