Summary & Overview
HCPCS L8623: Lithium Ion Battery for Cochlear Implant Speech Processor, Replacement
HCPCS Level II code L8623 identifies a replacement lithium ion battery used with a cochlear implant device speech processor when the power unit is not ear-level. As a component-level durable medical equipment item, this code matters nationally because batteries are essential consumable parts that enable long-term function of speech processors for recipients of cochlear implants. Coverage, reimbursement, and billing practices for replacement batteries affect device usability, patient out-of-pocket costs, and supplier workflow across payers.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical and billing context, typical sites of service, and common billing considerations. The publication provides benchmarks on coverage patterns and prior authorization tendencies, summarizes relevant policy updates affecting component replacement supplies, and outlines typical clinical scenarios in which replacement batteries are billed.
This summary equips billing staff, audiology providers, and DME suppliers with a national view of where L8623 fits in coding and coverage practices, and what operational and policy factors commonly influence reimbursement for replacement lithium ion batteries for cochlear implant speech processors.
Billing Code Overview
HCPCS Level II code L8623 describes a lithium ion battery for use with cochlear implant device speech processor, other than ear level, replacement, each. This item represents a replacement power source designed for non–ear-level speech processor configurations that are part of an implanted cochlear system.
-
Service type: Durable medical equipment component — replacement battery for cochlear implant speech processor
-

Clinical & Coding Specifications
Clinical Context
A 45-year-old adult with a surgically implanted cochlear implant presents to an outpatient audiology clinic when the external speech processor fails to power on due to a depleted or damaged non–ear-level lithium ion battery. The device is an off-body (body-worn or table-top) speech processor that uses a replaceable lithium ion battery. The clinical workflow includes verification of the speech processor model and battery type, confirmation that the internal implant remains functional via device telemetry or patient-reported hearing performance, replacement of the battery with a manufacturer-specified lithium ion battery (L8623) on-site, testing of processor function and sound quality, and documentation of the battery replacement in the medical record. The service is billed as a supply/replacement item using HCPCS Level II code L8623 for the single replacement battery. Typical sites of service are outpatient audiology clinics, hospital outpatient departments, or durable medical equipment suppliers. Typical patients include adults and children with established cochlear implants requiring a replacement external battery due to routine wear, accidental damage, or battery failure.
