CPT 99454: Remote Patient Monitoring Device Supply, 16-30 Days
CPT 99454 covers the RPM device supply with daily recordings or programmed alert transmissions over a 30-day period, requiring at least 16 days of data. In 2026 Medicare pays about $52.11 (1.56 total RVUs times the $33.4009 conversion factor), the same in facility and non-facility.

What is CPT 99454 used for?
CPT 99454 covers the RPM device supply, the device with daily recordings or programmed alert transmissions, over a 30-day period. It is the recurring device charge that follows the one-time setup (99453) and pairs with the treatment-management codes. The device must be FDA-defined and monitor a physiologic parameter, and it is reported once per patient per 30-day period.
Unlike the management codes, 99454 pays for the equipment and data transmission itself, not for clinician time. Its billability turns entirely on how many days of readings the device actually captured in the period, which makes accurate day-counting the whole game for this code.
How much does 99454 pay in 2026?
99454 carries 1.56 total RVUs in both settings. At the 2026 conversion factor of $33.4009 that is about $52.11, facility and non-facility alike, per 30-day period. As the recurring backbone of RPM revenue, it repeats each qualifying period for as long as monitoring is medically necessary. Model your panel's recurring RPM revenue on the Medicare fee calculator.
The 16-day rule and what changed in 2026
The gating requirement is data days, not a calendar month. To bill 99454 for a 30-day period, the device must transmit at least 16 days of readings within that period:
- Count actual transmission days in the 30-day period.
- If 16 or more, bill 99454.
- If 2-15, bill the new 2026 shorter-duration device-supply code (99445) instead, at the same rate.
- If fewer than 2 days, there is nothing to bill for that period.
Example: a hypertensive patient transmits blood-pressure readings on 19 of 30 days; that clears the threshold and supports a 99454 at about $52.11 for the period. A month with only 12 readings is a shorter-code claim, not a denied 99454.
Frequently asked questions
To bill 99454 for a 30-day period, the device must transmit at least 16 days of readings within that period. Fewer than 16 days of data means the code is not billable for that period. This is the single most common reason RPM device-supply claims are denied or recouped.
The 2026 national allowed amount is about $52.11 (1.56 total RVUs times $33.4009), the same in facility and non-facility settings. It is billed per 30-day period, once per patient, and forms the recurring backbone of RPM revenue.
Yes. For 2026 CMS added a new shorter-duration device-supply code (99445) for 2-15 days of data in a 30-day period, priced at the same rate as 99454. The two are not additive; bill 99454 for 16 or more days and the new shorter code for 2-15 days. Verify the correct code against your actual transmission days.
