CPT code 99445 represents the supply of one or more devices used for remote physiologic monitoring (RPM) when monitoring occurs for two to 15 days in a 30‑day period. Nationally, this code reflects growing adoption of RPM technologies that enable clinicians to monitor patients outside traditional settings, supporting chronic disease management, early intervention, and continuity of care. Coverage and coding clarity for device-supply services affect billing workflows and access to RPM services across payers.

Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code's clinical purpose and service setting, along with benchmark and policy context where available. The publication covers typical billing considerations, payer coverage patterns, and how 99445 fits into the broader RPM service line. It also highlights where input data is not available and directs readers to sections detailing related codes, modifiers, and reimbursement guidance when present.

This summary is intended for health system revenue cycle staff, clinicians implementing RPM programs, and policy analysts tracking telehealth and remote monitoring code use and coverage trends nationally.
