L6640 Shoulder Abduction Joint HCPCS Reimbursement | OpenPayer

Summary & Overview

HCPCS Level II L6640: Upper Extremity Shoulder Abduction Joint, Pair

HCPCS Level II code L6640 identifies upper extremity additions for a shoulder abduction joint, billed as a paired component for prosthetic and orthotic devices. Nationally, this code is relevant to durable medical equipment suppliers, prosthetics and orthotics clinics, and outpatient orthopedic practices that provide componentry to restore or support shoulder abduction in patients with upper limb impairment. The code matters because it standardizes billing for a specific component set that can affect device configuration, clinical outcomes, and payer coverage determinations.

Key payers in this analysis include 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 the clinical context for use. The publication provides benchmarks and coverage patterns where available, notes common billing modifiers and administrative considerations, and summarizes how L6640 fits into prosthetic/orthotic service lines and supply chains. Data not available in the input is noted where applicable.

Billing Code Overview

HCPCS Level II code L6640 describes upper extremity additions for a shoulder abduction joint, sold as a pair. This code covers components used to add or augment a shoulder abduction joint in prosthetic or orthotic devices for the upper limb.

Service type: Prosthetic/orthotic component supply and fitting
Typical site of service: Durable medical equipment supplier, prosthetics/orthotics clinic, or outpatient orthopedic/prosthetic facility

Clinical & Coding Specifications

Clinical Context

A patient with a history of shoulder weakness and limited abduction due to a prior amputation, congenital limb deficiency, or prosthetic fitting need presents to a prosthetics clinic for component augmentation. The clinician evaluates the residual upper extremity anatomy and functional goals, documents range of motion limitations, and determines a shoulder abduction joint addition to the prosthetic socket is required. The prosthetist orders L6640 (upper extremity additions, shoulder abduction joint, pair) to be fabricated and integrated into a myoelectric or body-powered prosthesis. Typical workflow: initial evaluation and measurements; selection of appropriate shoulder abduction joint components; fabrication and assembly in the prosthetic lab; patient fitting and alignment; functional training and follow-up adjustments. Typical sites of service are outpatient prosthetics/orthotics clinics, rehabilitation hospitals, and specialized durable medical equipment (DME) suppliers that provide prosthetic fabrication and fittings.
