Summary & Overview
HCPCS E2394: Power Wheelchair Drive Wheel Replacement
HCPCS Level II code E2394 designates a replacement drive wheel (excluding the tire) for power wheelchairs. As a DME accessory code, it covers individual replacement components necessary to maintain or restore powered mobility equipment. Nationally, such accessory codes matter because they affect device uptime, repair workflows, and claims processing for patients who rely on power wheelchairs for mobility and independence. Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. This publication provides a concise overview of what E2394 represents, typical sites of service, and which payers commonly reimburse replacement accessories. Readers will find benchmarks for coverage and reimbursement practices, common billing considerations for DME suppliers and repair vendors, and the clinical context for when a drive wheel replacement is billed rather than full-device replacement. Data on modifiers, associated taxonomies, and ICD-10 diagnoses are not provided in the input. Data not available in the input will be noted where relevant.
Billing Code Overview
HCPCS Level II code E2394 describes a power wheelchair accessory: a drive wheel (excludes tire), any size, replacement only, each. This item is a component replacement for powered mobility devices and is specific to the drive wheel assembly (the wheel hub and related non-tire parts) rather than the pneumatic or solid tire itself.
Service type: Durable Medical Equipment (DME) accessory, replacement part
Typical site of service: Durable medical equipment supplier, outpatient DME retail setting, or maintenance/repair facility for mobility devices
Clinical & Coding Specifications
Clinical Context
A power wheelchair user presents for a replacement drive wheel after the original wheel sustained damage from repeated curb strikes and wear. The patient is an adult with mobility impairment using a power-operated wheelchair as durable medical equipment. A supplier or durable medical equipment provider evaluates the wheelchair, documents the damaged drive wheel, photographs the defect, and confirms the need for a replacement drive wheel only (no tire). The supplier orders the replacement part coded as E2394 (power wheelchair accessory, drive wheel excludes tire, any size, replacement only, each). Billing typically occurs after receipt of the replacement part and delivery to the patient at an outpatient durable medical equipment facility, the patient’s home, or a skilled nursing facility. Documentation includes the patient’s mobility diagnosis, justification for replacement (e.g., broken hub, bent rim, stripped mounting), the wheelchair make and model, part serial numbers, and proof that the tire is not included in the billed item.
