Complete guide to remote patient monitoring (RPM) for US hospitals — RPM devices, CMS CPT billing codes, chronic care management integration, readmission reduction, and RPM software.
RPM reduces hospital readmissions by 38% and generates $300K-$600K per year in Medicare reimbursement for a 200-bed hospital. CMS expanded RPM coverage in 2026, making it a revenue-generating program.

Frequently Asked Questions
- What is remote patient monitoring (RPM) in hospitals?
- RPM uses connected devices to monitor patients' vital signs and health data remotely — blood pressure, glucose, weight, heart rate, SpO2. Data flows to the hospital in real-time, enabling early intervention. RPM reduces readmissions by 38% and is reimbursed by Medicare.
- How much does Medicare pay for RPM services?
- Medicare pays $50-120/month per patient for RPM services. CPT 99453 (initial setup, $19), CPT 99454 (device supply, $55), CPT 99457 (first 20 min monitoring, $50), CPT 99458 (additional 20 min, $40). A 200-bed hospital with 500 RPM patients can generate $300K-$600K per year.
- What devices are used for hospital RPM?
- Common RPM devices: blood pressure cuffs, glucose meters, pulse oximeters, weight scales, ECG monitors, spirometers, and wearable activity trackers. Devices must be FDA-cleared and connect via Bluetooth/cellular to transmit data to the hospital platform.
