HCPCS Level II code E0490 identifies the power source and control electronics unit for an oral appliance that delivers neuromuscular electrical stimulation to the tongue muscle, controlled by a hardware remote. This device-oriented code matters nationally as use of device-based neuromuscular stimulation expands for dysphagia and other tongue motor disorders, creating billing, coverage, and device classification considerations for clinicians, suppliers, and payers. Key payers in national analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find an overview of the clinical role of the device and the typical sites of service, followed by benchmarking and coverage patterns across major payers, common billing modifiers, and coding relationships. The publication summarizes reimbursement considerations, utilization benchmarks where available, and policy implications for DME suppliers and therapy providers. It also highlights gaps where input or additional documentation may affect coverage decisions. Data not available in the input is noted where applicable.
