HCPCS E2328: Power Wheelchair Head or Extremity Control Interface - OpenPayer

Summary & Overview

HCPCS E2328: Power Wheelchair Head or Extremity Control Interface

HCPCS Level II code E2328 represents an electronic proportional head or extremity control interface for power wheelchairs, including associated electronics and fixed mounting hardware. These interfaces are critical assistive technology for individuals with limited hand function, enabling independent mobility and participation in daily activities. National interest centers on access, appropriate device selection, and consistent coverage for necessary mobility aids.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the code’s clinical purpose, typical service settings, and payer coverage considerations. The publication summarizes benchmark topics such as common coverage policies, documentation expectations, and supply/installation contexts. It also highlights clinical context: intended users, functional goals, and how proportional head or extremity controls integrate into power wheelchair systems.

Data not available in the input includes specific payer policy language, utilization benchmarks, and associated ICD-10 diagnoses. The content is written for a national audience to clarify the code’s purpose and what to expect when seeking coverage for an electronic control interface under HCPCS Level II code E2328.

Billing Code Overview

HCPCS Level II code E2328 describes a power wheelchair accessory: an electronic, proportional head control or extremity control interface, including all related electronics and fixed mounting hardware. This device enables users to operate a power wheelchair through head movements or limited extremity motions by converting proportional input into wheelchair drive commands.

Service Type: Assistive mobility device accessory — electronic control interface

Typical Site of Service: Durable medical equipment setting, including supplier distribution sites, outpatient clinics that dispense mobility aids, and patient homes when fitted or installed by a supplier or clinician.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult with severe upper motor neuron or neuromuscular impairments (for example, advanced spinal cord injury, amyotrophic lateral sclerosis, cerebral palsy, or severe stroke) who cannot reliably operate a standard joystick on a power wheelchair. The patient has intact cognitive ability to control proportional electronic interfaces or has a caregiver trained to assist with setup and programming. Clinical workflow: evaluation by a rehabilitation physician or therapist to determine need for alternative control; assessment of residual voluntary movement (head, chin, tongue, breath, or extremity motion) and sensory/cognitive capacity; selection of an electronic proportional head or extremity control interface; trialing options (may include temporary mount or simulator); ordering the accessory using billing code E2328; device fitting and mounting on the power wheelchair by a durable medical equipment (DME) vendor; programming and tuning of proportional signals by a technician or assistive technology professional; occupational therapy training for the patient and caregiver; follow-up visits to document function, make adjustments, and verify continued medical necessity.
