Summary & Overview
HCPCS L3764: Elbow-Wrist-Hand Orthosis, Custom-Fabricated
HCPCS Level II code L3764 represents a custom-fabricated elbow-wrist-hand orthosis that includes one or more nontorsion joints, elastic bands or turnbuckles, and may include a soft interface and straps; the code encompasses fabrication plus fitting and adjustment. This orthotic is used to support, align, or protect the elbow, wrist, and hand in patients with neuromuscular weakness, post-surgical needs, or traumatic injury, and is relevant to durable medical equipment (DME) and rehabilitation services nationally.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of coverage and billing context for L3764, benchmarks where available, clinical indications that typically drive use, and relevant policy considerations affecting DME and orthotics reimbursement. The summary highlights common settings for service delivery—outpatient orthotics/prosthetics clinics, hospital outpatient departments, and rehabilitation facilities—and clarifies that the code covers both custom fabrication and the associated fitting and adjustment services.
This publication provides practical reference material for billing staff, orthotics providers, and policy analysts seeking a national-level understanding of L3764, including payer coverage considerations and areas where local or plan-specific policy differences commonly occur.

Clinical & Coding Specifications
Clinical Context
A 57-year-old right-handed patient presents to an orthopedic hand clinic four weeks after a distal radius fracture treated nonoperatively with closed reduction and casting. They report persistent wrist and distal forearm pain, weakness with gripping, and difficulty performing activities of daily living. The orthopedist assesses residual instability and restricted wrist/elbow motion and prescribes a custom-fabricated elbow-wrist-hand orthosis to immobilize the wrist and forearm while allowing controlled elbow movement. The orthotist performs measurement, fabrication or ordering of the L3764 device, fits the orthosis in clinic, adjusts straps and elastic components for comfort and function, and documents the fitting and adjustments.
Typical clinical workflow:
-
Referral from orthopedic surgeon or hand therapist for splinting after fracture, tendon repair, nerve injury, or chronic instability.
-
Initial assessment and measurements by an orthotist or occupational therapist.
-
Custom fabrication or customization of a prefabricated device that includes fitting, adjustment, and patient education on use and skin care.
-
Follow-up visits for adjustments, monitoring skin integrity, and documenting continued medical necessity for orthosis use or replacement.
Typical site of service: outpatient orthopedic clinic, hand surgery clinic, ambulatory surgery center (for perioperative fitting), or durable medical equipment supplier with clinical fitting area.
Typical patient scenario: adult recovering from distal radius fracture or wrist/forearm tendon repair requiring a custom elbow-wrist-hand orthosis with non-torsion joints, elastic bands or turnbuckles to control motion and support healing, fitted and adjusted by an orthotist or therapist.
