Summary & Overview

HCPCS Q0495: Battery/Power Pack Charger for Ventricular Assist Device

HCPCS Level II code Q0495 designates a replacement battery/power pack charger for electric or electric/pneumatic ventricular assist devices (VADs). The code covers the supply of a charger component used to recharge VAD power sources and is relevant because VAD support is a growing area of advanced cardiac care where reliable equipment replacement is critical for patient safety and continuity of therapy. Nationally, proper coding ensures equipment is billed and tracked consistently across payers and care settings.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of code definition and clinical context, typical sites of service for billing, and the kinds of benchmarks and policy elements that commonly accompany durable medical equipment replacement codes. The publication outlines coverage considerations, common modifiers and billing practices (listed separately), and potential points of payer variation that affect claims processing and reimbursement. It also highlights where data was unavailable in the input so users can anticipate what additional information may be needed for claim submission and policy comparison.

Billing Code Overview

HCPCS Level II code Q0495 describes a battery/power pack charger for use with electric or electric/pneumatic ventricular assist device, replacement only. This code represents the supply of a replacement charger specifically intended to power external components of a ventricular assist device (VAD) system.

Service Type: Durable Medical Equipment (DME) supply — replacement part

Typical Site of Service: Outpatient setting, home use, or durable medical equipment supplier

Data not available in the input.

Clinical & Coding Specifications

Clinical Context

A patient with an implanted electric or electric/pneumatic ventricular assist device (VAD) presents to durable medical equipment (DME) services or a hospital biomedical engineering department because the external battery charger for the VAD power pack has failed or been lost. Typical patients are adults with advanced systolic heart failure supported by a left ventricular assist device (LVAD) or biventricular assist device who require continuous external battery management to maintain device operation during ambulation or transport. Workflow: clinician documents the need for a replacement battery/power pack charger after device interrogation and confirmation of charger failure; the DME supplier orders Q0495 as a replacement-only item; supplier documents device model, serial number, clinician prescription, and proof of prior charger loss/failure; training is provided to patient/caregiver on charger use, troubleshooting, and safe battery handling; billing is submitted with the appropriate modifier if required by payer policy.
