Remote Physiological Monitoring
Physiologic data, managed from home.
Remote Physiologic Monitoring (RPM) — sometimes called Remote Patient Monitoring — is the non-face-to-face collection and analysis of physiologic data used to understand a patient's health status and manage chronic or acute conditions.
The Basics
What RPM measures
RPM collects a wide range of health data at the point of care — vital signs, weight, blood pressure — and transmits it to clinicians in primary-care settings, hospitals, intensive-care units, and skilled-nursing facilities. The result: care teams can check in on patients and manage conditions between visits.
Commonly monitored conditions
- High blood pressure
- Diabetes
- Heart conditions
- Sleep apnea
- Asthma
- Weight loss or gain
Common RPM devices
- Blood pressure monitors
- Blood glucose monitors
- Pulse oximeters
- Weight scales
The Codes
RPM code families
RPM codes are classified as Evaluation and Management (E/M) services. Descriptors are simplified here — confirm exact wording and current rules before billing.
Set-up & data transmission
99453 covers initial device set-up and patient education; 99454 covers the device supply and transmission of readings. Each is billed once per patient, per 30 days — and only when at least 16 days of data have been collected on at least one device.
Interpretation & management time
99457 is the first 20 minutes of a clinician's interpretation and real-time, interactive communication with the patient or caregiver each month; 99458 is each additional 20 minutes. 99091 covers collection and interpretation of physiologic data requiring at least 30 minutes every 30 days.
Self-measured blood pressure (SMBP)
99473 covers patient education, training, and device calibration — billed once per device. 99474 is billed monthly for treatment decisions based on the average of the patient's self-reported readings.
Continuous glucose monitoring (CGM)
Set-up, calibration, training, and analysis for patient-provided (95249) or office-provided (95250) equipment, plus interpretation and report (95251). Use modifier -25 when reporting 95250 or 95251 alongside an E/M service on the same day.
Before You Bill
Requirements for billing RPM
RPM is reimbursed only when specific conditions are met. Miss one of these and the claim is at risk of denial.
- Established relationship — the patient must already have a relationship with the clinician, including a prior E/M service (which may be done via telehealth).
- 16-day minimum — monitoring must occur for at least 16 days of a 30-day period for codes 99453 and 99454.
- Once per 30 days — a patient's services are billed only once per 30-day period, even with multiple devices.
- Physician or supervised clinician — 99457 and 99458 may be billed only by a physician, or a clinician under general supervision, otherwise eligible to bill E/M services.
- FDA medical device — the device must meet the FDA's definition of a “medical device.”
