Summary & Overview
HCPCS G9484: Remote In‑Home New Patient Evaluation and Management
HCPCS Level II code G9484 designates a synchronous, real‑time remote in‑home evaluation and management visit for a new patient, authorized for use within a Medicare‑approved CMS Innovation Center demonstration project. The service requires a comprehensive history, comprehensive examination, and medical decision making of moderate complexity, typically lasting about 45 minutes via interactive audio and video. Nationally, this code reflects expanding telehealth models that extend E/M services into patients' homes for moderate‑to‑high severity problems.
Key payers relevant to this code include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an explanation of the clinical service and operational context, payer coverage landscape, common billing modifiers, and where this code fits relative to telehealth E/M services. The publication also outlines typical sites of service, service type definitions, and practical considerations for coding consistency and claims adjudication within innovation demonstration settings. This summary is intended to inform clinicians, billing professionals, and policy analysts about the code's purpose, scope, and implications for remote new‑patient care delivery at a national level.
Clinical & Coding Specifications
Clinical Context
A 72-year-old Medicare beneficiary enrolled in a CMS Innovation Center demonstration presents for an initial remote in-home evaluation for new patient management due to progressive shortness of breath and new-onset cough over two weeks. The patient resides in a rural area with limited access to in-person specialty care. A primary care physician (family medicine) schedules a real-time interactive audio-video telehealth visit using secure telemedicine technology. The clinician conducts a comprehensive history (medical, social, medication, review of systems), a comprehensive examination adapted to virtual assessment (visual inspection of respiratory effort, pulse oximetry reading provided by caregiver, inspection of oropharynx and extremities), and performs medical decision making of moderate complexity (differential diagnosis including heart failure vs. pneumonia, ordering chest radiograph and pulse oximetry trends, initiating empiric treatment and arranging urgent in-person imaging). Counseling and coordination of care are completed with the patient and family, and with a local radiology center and home health agency to arrange follow-up. The encounter lasts approximately 45 minutes of face-to-face interactive time via real-time audio and video, consistent with the three required components for billing G9484 in the demonstration project.
