CPT code 64584 covers surgical removal of a hypoglossal nerve neurostimulator system, including the electrode array, pulse generator, and distal respiratory sensor electrode or array. This procedure is clinically significant because hypoglossal nerve stimulation is an established surgical therapy for obstructive sleep apnea; removal procedures are necessary for device complications, battery depletion, device upgrades, or infection management. Nationally, accurate coding for explantation affects surgical quality reporting, device management workflows, and payment integrity.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, expected sites of service, and common billing considerations tied to this service type. The publication provides benchmarks where available, notes on payer coverage patterns, and explanations of clinical scenarios that typically generate use of this code. It highlights operational implications for ambulatory surgical centers and hospital operating rooms handling device removal, and summarizes documentation elements that commonly support medical necessity for explantation.
