Summary & Overview
CPT 64583: Hypoglossal Nerve Neurostimulator Electrode Revision
Headline: CPT code 64583: Revision or Replacement of Hypoglossal Neurostimulator Electrode Array
Lead: CPT code 64583 designates revision or replacement of a hypoglossal nerve neurostimulator electrode array and one or more distal respiratory sensor electrodes, including reconnection to an existing pulse generator. The procedure is clinically significant for managing obstructive sleep apnea by restoring or improving upper airway neurostimulation when implanted components fail, migrate, or require upgrade.
CPT code 64583 matters nationally because increasing utilization of implantable neurostimulation for sleep-disordered breathing intersects with device longevity, revision rates, and payer coverage policies. Major payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. BUCA is not listed as a payer.
Readers will find a concise overview of the code’s clinical intent and service setting, a summary of prevalent payer coverage frameworks, and benchmarks where available. The publication highlights common billing and coding considerations, typical sites of service, and clinical context for why revisions or replacements are performed. Data not provided in the input—such as specific coverage edits, frequency benchmarks, or ICD-10 pairings—is noted as unavailable in source materials.
Billing Code Overview
CPT code 64583 describes the revision or replacement of a hypoglossal nerve neurostimulator electrode array and one or more distal respiratory sensor electrodes, including connection to an existing pulse generator. The hypoglossal nerve innervates the tongue; this procedure is performed to manage obstructive sleep apnea by stabilizing upper airway musculature through neurostimulation.
-
Service type: Surgical implant revision/replacement of a neurostimulator electrode array with respiratory sensor electrodes, including device reconnection.
-
Typical site of service: Ambulatory surgery center or hospital operating room, often under general anesthesia for device revision and lead handling.
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with moderate-to-severe obstructive sleep apnea (OSA) and intolerance to continuous positive airway pressure (CPAP) presents for revision of an implanted hypoglossal nerve neurostimulator electrode array. The patient reports return of OSA symptoms with device alarms and loss of tongue stimulation on one side. Preoperative evaluation includes device interrogation by the implanting center, polysomnography review showing recurrent obstructive events, and focused neurologic and airway examination. The procedure is performed in an ambulatory surgery center or hospital operating room under general anesthesia with intraoperative neurophysiologic monitoring and device programmer support. The surgeon re-enters the previous submental/submandibular incision, identifies the hypoglossal electrode array and distal respiratory sensor electrodes, revises or replaces malfunctioning leads, tests electrode impedance and stimulation thresholds, and reconnects the revised electrode array to the existing pulse generator. Postoperative workflow includes device testing, wound care instructions, brief post-anesthesia monitoring, and scheduling for follow-up device programming and sleep testing.
