CPT 99454: RPM Device Supply — 16+ Days of Data.
CPT 99454 covers the supply of a remote patient monitoring device with daily recording(s) or programmed alert(s) transmission, requiring a minimum of 16 days of data collection within a 30-day period. Each transmission day must include at least one physiologic reading from an FDA-cleared medical device. This code reimburses the ongoing device supply and data transmission infrastructure, not the clinical review of data.
Quick Answer
What is CPT 99454?
CPT 99454 is the Medicare billing code for RPM device supply, covering the provision of FDA-cleared monitoring devices with daily data transmission. It reimburses $52.11 per patient per month under the 2026 CMS fee schedule and requires at least 16 days of physiologic data collection within a 30-day period. The code is billed once per patient regardless of how many devices are used. For patients with fewer than 16 days of data, the new 2026 code 99445 covers the 2-15 day range.
Documentation
Documentation requirements.
Device type and FDA clearance documentation for each monitoring device
Daily transmission log showing specific dates and physiologic readings received
Evidence of 16 or more days of data transmission within the 30-day billing period
Type of physiologic data collected (e.g., blood pressure, weight, glucose, SpO2)
Documentation of any alert triggers generated by the device and clinical responses taken
Written patient consent for RPM services obtained prior to initiating monitoring
Scenarios
Common billing scenarios.
Patient transmits blood pressure readings 22 days in a month
BillableA patient with hypertension uses an FDA-cleared blood pressure cuff and transmits readings on 22 out of 30 days. The 16-day minimum is met, so 99454 can be billed for the month.
Patient only transmits data on 12 days
Not BillableA patient with a weight scale transmits weight readings on only 12 days within the 30-day period. The 16-day minimum is not met, so 99454 cannot be billed. Consider billing 99445 (2-15 days) instead.
Multiple devices for the same patient
BillableA patient uses both a blood pressure cuff and a weight scale, transmitting data from both devices daily. CPT 99454 is billed once per patient per 30-day period regardless of how many devices are used — it is not billed per device.
Patient uses a consumer fitness tracker (not FDA-cleared)
Not BillableA patient wears a consumer-grade smartwatch that tracks heart rate and transmits data daily. Because the device is not FDA-cleared as a medical device, 99454 cannot be billed. RPM requires FDA-cleared devices.
FAQ
Common questions about CPT 99454.
What is CPT 99454?
CPT 99454 is the Medicare billing code for Remote Patient Monitoring (RPM) device supply, covering the provision of an FDA-cleared monitoring device with daily data transmission. It requires at least 16 days of physiologic data collection within a 30-day period and reimburses $52.11 per month under the 2026 Medicare fee schedule.
How much does CPT 99454 reimburse in 2026?
CPT 99454 reimburses $52.11 per patient per month under the 2026 CMS national non-facility rate, based on an RVU of 1.56 and the 2026 conversion factor of $33.40. Geographic adjustments (GPCI) may cause the actual payment to vary by location.
What is the 16-day rule for 99454?
CPT 99454 requires that the patient's FDA-cleared device transmits physiologic data on at least 16 out of 30 days within the billing period. Each qualifying day must include at least one valid physiologic reading. If the patient transmits data on fewer than 16 days, consider billing the new 2026 code 99445 (which covers 2-15 days of data).
Can 99454 be billed per device or only per patient?
CPT 99454 is billed once per patient per 30-day period, regardless of how many monitoring devices the patient uses. A patient using a blood pressure cuff, weight scale, and pulse oximeter simultaneously still generates only one 99454 claim per month.
What is the difference between 99454 and 99445?
Both codes cover RPM device supply, but they differ in the data transmission threshold. CPT 99454 requires 16 or more days of data within a 30-day period, while 99445 (new for 2026) covers 2-15 days. The codes are mutually exclusive — only one can be billed per patient per 30-day period. Both reimburse $52.11 per month.
Does 99454 require FDA-cleared devices?
Yes, CPT 99454 specifically requires FDA-cleared medical devices that collect and electronically transmit physiologic data. Consumer wellness devices (fitness trackers, smartwatches, non-FDA-cleared apps) do not qualify. Common qualifying devices include cellular blood pressure cuffs, connected weight scales, pulse oximeters, and continuous glucose monitors.
