Summary & Overview
HCPCS E2359: Power Wheelchair Sealed Lead Acid Battery
HCPCS Level II code E2359 designates a sealed lead acid battery (group 34) used as a power wheelchair accessory, such as gel cell or absorbed glassmat batteries. The code identifies billed supply items that support mobility and independence for beneficiaries who rely on power wheelchairs. Nationally, proper coding of mobility device components affects beneficiary access to durable medical equipment and the accuracy of claims processing and payment for suppliers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for replacement batteries, common billing practices and modifiers used with durable medical equipment charges, payer coverage patterns where available, and benchmark perspectives. The publication summarizes documentation expectations and typical sites of service for these accessories, and it flags where supplemental policy details or medical necessity criteria may influence coverage decisions.
This summary is intended for coding, billing, and policy professionals seeking concise guidance on the purpose and billing context of E2359, plus what to expect when preparing claims for power wheelchair batteries nationally. Data not available in the input is noted where applicable in the detailed sections.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult or pediatric wheelchair user whose power wheelchair uses sealed lead acid batteries (gel cell or absorbed glass mat) and requires replacement of a single battery due to end of useful life, failure to hold charge, or damage. The clinical workflow begins with a wheelchair service evaluation by a durable medical equipment (DME) provider or rehabilitation therapist documenting functional need for the power mobility device. The patient or caregiver reports reduced range or power interruptions; battery testing (voltage and load testing) is performed by a qualified DME technician. When testing confirms a failed battery, the DME provider orders replacement of the battery accessory coded as E2359. The technician installs the replacement battery, verifies correct polarity and secure mounting, programs any battery-related settings if required by the manufacturer, and demonstrates operation to the patient. Documentation includes battery test results, reason for replacement, product model and group (sealed lead acid, gel cell/AGM), itemized invoice with E2359, and proof of delivery and patient acceptance. Typical sites of service are the DME supplier facility, the patient’s home, outpatient rehabilitation clinics, or skilled nursing facilities where the wheelchair is used and maintained.
