Summary & Overview
CPT 99454: Remote Physiologic Monitoring Device Supply, 16–30 Days
CPT code 99454 identifies the supply of one or more devices used for remote physiologic monitoring that occurs for 16 to 30 days in a 30‑day period. The code captures an increasingly important category of virtual care that enables continuous physiologic data collection outside traditional clinical settings, supporting chronic disease management and post‑acute monitoring at scale. Nationally, growth in remote physiologic monitoring reflects broader adoption of digital health tools and payer policy updates that recognize device supply and remote monitoring as distinct billable services.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of what CPT code 99454 represents, typical clinical and operational contexts for its use, and which payers commonly provide coverage. The publication outlines benchmark considerations, common billing modifiers and coding context, and how 99454 relates to other remote monitoring services.
This summary provides clinicians, billing professionals, and policy analysts with a concise reference on the code's clinical intent, service setting, and payer landscape.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with chronic heart failure is enrolled in a remote physiologic monitoring program. The clinic supplies a wearable device that continuously measures weight and thoracic impedance and transmits data to the clinician for 16 to 30 days within a 30-day period. The clinical workflow: the clinician or clinic staff orders and supplies the monitoring device; staff educates the patient on device use and confirms connectivity; the device collects physiologic data over the monitoring interval; staff or remote monitoring vendor reviews and screens incoming data; the clinician reviews abnormal alerts, adjusts therapy as needed, documents findings and care decisions in the medical record, and bills for the device supply and monitoring month using 99454 for the qualifying 16–30 day period. Typical site of service is the outpatient clinic or ambulatory care setting, with devices supplied to the patient’s home for remote use. Common clinical scenarios include management of heart failure, hypertension, chronic obstructive pulmonary disease with remote spirometry or oxygenation tracking, and post-discharge monitoring after cardiac procedures.
