HCPCS L3995: Addition to Upper Extremity Orthosis, Sock for Fracture

HCPCS Level II code L3995 denotes an addition to an upper extremity orthosis: a sock used for fracture care or equivalent purposes. This code captures discrete orthotic accessories supplied in addition to a primary upper extremity device and is relevant to clinicians, orthotics suppliers, and payers managing durable medical equipment (DME) claims. Nationally, orthotic accessory coding affects reimbursement, documentation requirements, and inventory tracking for upper-limb fracture management.

Key payers included in this overview are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what the code represents, typical sites of service, and which payers commonly cover such orthotic additions. The publication outlines benchmarking context, common billing modifiers and coding considerations, and clinical context for use with upper extremity fractures and protective orthoses. Where specific payer policy details are not provided in the input, the section notes "Data not available in the input." This summary equips billing managers and policy analysts with the core facts needed to locate more detailed payer policies and to align documentation and billing practices with national orthotic accessory standards.

Billing Code Overview

HCPCS Level II code L3995 describes an addition to an upper extremity orthosis in the form of a sock intended for fracture management or an equivalent purpose. This item is billed as a discrete accessory or addition to a primary upper extremity orthotic device.

Service type: Durable medical equipment / orthotic accessory
Typical site of service: Outpatient clinic, orthotics/prosthetics supplier, ambulatory surgical center, or other outpatient settings where orthoses are fabricated, fitted, or dispensed.

Clinical Context

A patient presents to an outpatient orthopedic clinic after sustaining a distal radius fracture of the dominant wrist in a fall. The fracture has been reduced and immobilized in a temporary splint. The treating orthopedic clinician or certified orthotist prescribes a removable upper extremity fracture orthosis with an accessory sock (cover) for padding, hygiene, or pressure redistribution. The orthotist measures the patient, fits an appropriate prefabricated or custom-molded orthosis, and adds L3995 as the line-item charge for the additional sock component supplied with the orthosis. Typical workflow includes evaluation, measurement and fitting, patient instruction on wear and care, and documentation of medical necessity and delivery. Typical sites of service are outpatient orthopedic clinics, ambulatory surgery centers (when dispensed post-procedure), and durable medical equipment supplier locations where upper-extremity orthoses are dispensed and adjusted.
