Summary & Overview
HCPCS C8008: Hypoglossal Nerve Neurostimulator Array Revision or Replacement
HCPCS Level II code C8008 designates the revision or replacement of a hypoglossal nerve neurostimulator array with reconnection to an existing pulse generator. This code applies to surgical procedures addressing device leads or arrays used for hypoglossal nerve stimulation, a therapy increasingly used for select patients with obstructive sleep apnea and other neurostimulation indications. Nationally, accurate reporting of this code matters for device surveillance, reimbursement consistency, and tracking of revision rates.
Key payers included in the coverage and benchmarking discussion are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and the administrative uses of C8008. The publication provides benchmarks where available, summarizes relevant policy or coding updates affecting billing and coverage, and clarifies common billing considerations tied to revisions or replacements of implanted neurostimulator arrays.
The analysis is intended for coding professionals, device program managers, and policy analysts seeking a national perspective on coding practice, payment alignment, and clinical scenarios that prompt use of C8008. Data not available in the input is noted where applicable in detailed sections below.
Billing Code Overview
HCPCS Level II code C8008 describes the revision or replacement of a hypoglossal nerve neurostimulator array including connection to existing pulse generator. This procedure involves surgical revision or exchange of the electrode array that stimulates the hypoglossal nerve, with reconnection to an existing implanted pulse generator.
-
Service type: Surgical revision or replacement of neurostimulator array
-
Typical site of service: Hospital inpatient or outpatient surgical setting (including ambulatory surgery centers) depending on clinical indications and facility capabilities
Clinical & Coding Specifications
Clinical Context
A typical patient is a 55-year-old with an existing hypoglossal nerve neurostimulator implanted for obstructive sleep apnea who presents with focal lead malfunction or electrode migration resulting in loss of tongue stimulation and recurrent OSA symptoms. After device interrogation confirms abnormal lead impedance or intermittent stimulation and conservative measures fail, the patient is scheduled for a revision or replacement of the hypoglossal nerve neurostimulator array with reconnection to the existing pulse generator. The clinical workflow includes preoperative evaluation (history, airway assessment, device interrogation, imaging as needed), perioperative anesthesia and device programming planning, surgical exploration of the neurostimulator pocket and cervical subplatysmal region, removal or replacement of the defective electrode array along the hypoglossal nerve, intraoperative testing of lead function and stimulation thresholds, connection of the revised array to the existing pulse generator, wound closure, and postoperative device reprogramming and sleep study or device-driven titration as indicated. Typical follow-up includes wound check, device telemetry, and assessment of sleep parameters and symptom improvement.
