Summary & Overview
HCPCS E2384: Power Wheelchair Pneumatic Caster Tire, Replacement
HCPCS Level II code E2384 identifies a replacement pneumatic caster tire for power wheelchairs. As a DME accessory code, it is important for device maintenance, patient mobility, and supply chain workflows across the United States. Replacement parts such as pneumatic caster tires affect durable medical equipment (DME) suppliers, home medical equipment providers, clinicians overseeing mobility devices, and payers managing durable equipment benefits.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find national benchmarks for coverage and payment practices, contextual information on clinical and operational use, and references to typical sites of service for dispensing and replacement. The publication outlines coding implications for billing replacement parts versus complete device replacement, common documentation elements used to support medical necessity, and areas where policy updates commonly arise (for example, rules distinguishing accessory replacement from new device procurement).
The analysis provides practical payor coverage considerations, typical billing scenarios, and a concise overview of how E2384 is used in practice without offering clinical directives. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A patient who uses a power wheelchair presents to a durable medical equipment (DME) supplier or wheelchair service clinic for replacement of a worn or damaged pneumatic caster tire. Typical patients include individuals with mobility-limiting neuromuscular disorders, spinal cord injury, stroke-related hemiparesis, or severe arthritis who rely on a power wheelchair for community mobility and activities of daily living. The clinical workflow begins when the patient or caregiver reports vibration, reduced steering control, frequent flats, or visible tire damage. A wheelchair technician inspects the front caster assembly, documents the need for a replacement tire, confirms the power wheelchair make/model, and verifies warranty or payer coverage. The technician orders accessory part E2384 (power wheelchair accessory, pneumatic caster tire, replacement only, each), obtains any required prior authorization from payors such as Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, or Medicare, and schedules installation. The replacement is performed in the clinic or during a home visit by a certified technician; the repair is documented with device serial numbers, part numbers, date of service, technician taxonomy, and associated diagnosis code(s) to support medical necessity. Billing uses HCPCS E2384 with an appropriate modifier when required, and accompanying documentation supports coverage limitations for replacement parts vs. full wheelchair replacement.
