Summary & Overview
HCPCS L6000: Partial Hand Prosthesis, Thumb Remaining
HCPCS Level II code L6000 represents a prosthetic or orthotic device for a partial hand amputation in which the thumb remains. This code identifies services and devices intended to restore hand function and dexterity when the thumb is preserved, a clinically significant scenario because thumb preservation often influences prosthetic design, functional outcomes, and coverage considerations.
Key payers in this national analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for partial hand prostheses when the thumb remains, common sites of service, and the types of benchmarks typically assessed for this service line. The publication outlines payer coverage patterns, utilization benchmarks, and policy considerations relevant to device provision and outpatient prosthetic services. It also summarizes coding inclusion for service lines where device fitting and follow-up care are billed.
This summary provides clinicians, billing professionals, and policy analysts with the essential facts about L6000, what it signifies clinically, which major payers are relevant, and what aspects of reimbursement and service delivery are commonly reviewed when this code is used. Data not available in the input are noted where applicable in detailed sections.
Billing Code Overview

The service represented by this code is the provision, fitting, or replacement of a prosthetic or orthotic device for a partially amputated hand where the thumb is preserved, focusing on functional restoration of hand use.
Service type: Prosthetic/orthotic device for partial hand amputation.
Typical site of service: Outpatient prosthetics clinic, specialty orthopedic or hand surgery clinic, or durable medical equipment supplier that provides prosthetic fittings and follow-up care.
Clinical & Coding Specifications
Clinical Context
A 54-year-old male construction worker presents to a hand surgeon after a crush injury that resulted in partial amputation of the dominant right hand with the thumb remaining. Initial care in the emergency department included hemorrhage control, analgesia, tetanus update, and sterile dressing. After stabilization and neurovascular assessment, the patient is scheduled for prosthetic evaluation and fabrication of a custom partial hand prosthesis coded as L6000 (Partial hand, thumb remaining). The clinical workflow includes: pre-prosthetic evaluation by a prosthetist and hand therapist; measurement and casting of the residual limb; selection of suspension and terminal device options to optimize pinch and grip given the preserved thumb; fabrication in the prosthetic lab; fitting and alignment; patient training in donning/doffing, hygiene, and functional use with occupational therapy; and follow-up adjustments and maintenance visits. Typical sites of service include an outpatient prosthetics clinic, hospital-based prosthetics department, or specialty rehabilitation facility. The typical patient scenario involves functional goal-setting for activities of daily living, return-to-work considerations, and interdisciplinary coordination among the surgeon, prosthetist, occupational therapist, and primary care provider.
