Remote Patient Monitoring (RPM)

Definition

Remote Patient Monitoring (RPM) is a Medicare-reimbursed care model where clinical staff review physiologic data (blood pressure, glucose, weight, SpO2, ECG, etc.) transmitted from a patient\u2019s connected medical device and conduct interactive communication with the patient at least monthly. RPM covers ongoing monthly care for patients with acute or chronic conditions where physiologic data informs clinical decisions, enabling proactive intervention before conditions worsen.

Core billing codes include: CPT 99453 covers one-time setup and patient education; CPT 99454 covers device supply billed each 30 days; CPT 99457 covers the first 20 minutes of RPM treatment management including required interactive communication per month; and CPT 99458 covers additional qualifying management time. In 2026, 99445 and 99470 also provide shorter collection-day and management-time pathways, subject to their own requirements. Verify payment for the actual service year, payer, locality, and setting.

Regulatory basis

RPM was established by CMS under the Medicare Physician Fee Schedule. RPM may address an acute or chronic condition using a device that meets the applicable medical-device definition and automatically collects and transmits physiologic data. Confirm an established relationship, consent, medical necessity, and eligible personnel. The device must collect and transmit physiologic data on at least 16 days per 30-day period for the supply code (CPT 99454) to apply.

Unlike some CMS programs, RPM does not impose a minimum number of chronic conditions \u2014 a single qualifying diagnosis is sufficient. The interactive communication required by CPT 99457 and 99458 must be with the patient or caregiver and must address the device data transmitted; it cannot be a generic check-in unrelated to the monitored readings.

Who uses it and when it applies

• Physicians and qualifying non-physician practitioners billing for ongoing chronic care under the Medicare Physician Fee Schedule
• Patients with an acute or chronic condition for which monitoring is medically necessary who have a connected monitoring device
• Care coordinators or clinical staff performing qualifying monthly interactive communication under the required supervision, with AI-powered systems supporting outreach, documentation, and escalation where appropriate
• Most common conditions: hypertension, diabetes, heart failure, COPD, CKD, post-surgical recovery
