Summary & Overview
HCPCS Level II L6708: Mechanical Voluntary-Opening Hand Terminal Device
HCPCS Level II code L6708 represents a mechanical, voluntary-opening prosthetic terminal device for the hand. These devices are a key component of prosthetic care for individuals with upper-limb amputation or limb difference and are used across rehabilitation, prosthetics, and outpatient durable medical equipment settings. Nationally, coverage and payment for prosthetic terminal devices influence access to functional restoration and long-term outcomes for beneficiaries who require upper-limb prostheses.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what L6708 denotes clinically, the typical sites of service, and the payer landscape addressed. The publication provides benchmarks on coverage patterns and payment considerations where available, a summary of relevant policy updates affecting prosthetic device coverage, and clinical context describing how a mechanical voluntary-opening terminal device fits into prosthetic care plans.
This summary is intended for clinicians, prosthetics providers, billing specialists, and policy analysts seeking a national-level reference for HCPCS Level II code L6708 and its implications for access, coverage, and device utilization. Data not available in the input will be noted in relevant sections.
Billing Code Overview
HCPCS Level II code L6708 describes a terminal device, hand, mechanical, voluntary opening, any material, any size. This device is a prosthetic terminal device intended to restore voluntary opening function of a prosthetic hand for users with upper-limb amputation or limb difference.
Service Type: Prosthetic upper-limb terminal device
Typical Site of Service: Prosthetics and orthotics clinics, outpatient rehabilitation centers, and durable medical equipment providers
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient with a transradial traumatic amputation distal to the wrist presents to a certified prosthetist in an outpatient prosthetics clinic for a functional terminal device. The patient retains wrist motion and forearm musculature and requests a voluntary opening mechanical hand for activities of daily living and light work tasks. The prosthetist performs a prosthetic evaluation, measures the residual limb, documents functional goals, and orders a custom or prefabricated mechanical voluntary-opening terminal device to attach to the existing prosthetic wrist or terminal adapter. Typical workflow includes initial evaluation, device selection and fitting, alignment and socket/adapter adjustments, patient training for voluntary opening control, and follow-up visits for fine tuning, maintenance, or replacement.
Typical site of service: Outpatient prosthetics clinic or orthotics/prosthetics department. In some cases, initial evaluation or urgent fitting may occur in a hospital outpatient department or rehabilitation facility.
Typical patient scenario: A patient with S48.091A (traumatic amputation of right forearm, initial encounter) or chronic residual limb following amputation seeks a L6708 voluntary-opening mechanical hand to restore grasp function for household tasks, work-related light lifting, and self-care. The device may be billed with applicable modifiers for laterality (LT/RT where used), repair or replacement circumstances, or professional/component distinctions when clinical documentation supports them.
