Summary & Overview
HCPCS L8624: Lithium Ion Battery for Cochlear Implant Speech Processor
HCPCS Level II code L8624 identifies a lithium ion replacement battery for ear-level speech processors used with cochlear implants and auditory osseointegrated devices. As a discrete supply code for a component essential to device function, L8624 matters nationally for access to ongoing device maintenance, out-of-pocket costs for patients, and durable medical equipment coverage policies across payers.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical role, typical sites of service, and payer relevance. The publication summarizes benchmark coverage practices, common billing modifiers used with this supply category, and policy considerations affecting replacement components. It also provides clinical context on why timely replacement batteries are necessary for continuous device function and patient communication outcomes.
This summary serves clinicians, billing staff, and policy analysts seeking a national perspective on coverage and coding for cochlear implant and auditory osseointegrated device replacement batteries. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A patient with a functioning cochlear implant or an auditory osseointegrated device presents to the audiology clinic reporting reduced runtime and intermittent loss of sound in the speech processor. The speech processor is an ear-level unit that uses a removable lithium ion battery. The audiologist inspects the processor, confirms the battery is depleted or fails quality testing, and documents the need for a replacement battery. The device manufacturer’s service or the clinic provides a replacement L8624 lithium ion battery, records the device lot/serial number, and updates the patient’s device inventory in the chart. Billing is submitted for the single replacement battery item, with the encounter coded to the patient’s underlying hearing disorder diagnosis (for example, sensorineural hearing loss or unilateral cochlear implantation status). Typical workflow steps include device inspection and testing by audiology, supply dispensing, documentation of battery model/serial, patient education on battery handling and charging, and billing of the replacement part using L8624.
