What 99454 covers
This service covers supplying a connected medical device that collects and transmits physiologic data, such as blood pressure, weight, pulse oximetry, or blood glucose, from the patient's home. The device provides daily recordings or programmed alert transmissions. It is usually billed by primary care, cardiology, endocrinology, and nephrology practices managing hypertension, heart failure, diabetes, or COPD. Clinical staff or an RPM vendor working under the billing practitioner typically provide the equipment and track whether data arrives. Readings must be captured and sent electronically by the device. Readings the patient types in or reports by phone do not count.
Report one unit per 30-day period only when data was transmitted on at least 16 days. If data came in on 2 to 15 days, report 99445 instead. The service has no physician work RVUs; its value comes almost entirely from practice expense for the device and data transmission. Documentation should identify the device, monitoring order, condition being monitored, and transmission dates. Medicare expects an established patient relationship. Only one practitioner may bill device supply for a patient in a given 30-day period. Treatment management time is reported separately with 99457 and, when supported, 99458.

99454 billing questions
How do I choose between 99454 and 99445?
Count the days with transmitted readings in the 30-day period. Report 99454 for 16 to 30 days and 99445 for 2 to 15 days. Do not report both for the same period.
Can multiple devices generate multiple units of 99454?
No. Report one unit per patient per 30-day period, regardless of how many devices the patient uses. Only one practitioner may bill RPM device supply for that patient during the period.
Do patient-reported readings count toward the 16 days?
No. The device must capture and transmit the data electronically. Values the patient enters manually, phones in, or writes in a log do not qualify.
Can 99454 be billed without 99457?
Yes. Device supply and treatment management are separate services. Report 99457 only when at least 20 minutes of treatment management and the required interactive communication occur during a calendar month.
Can RPM device supply be billed alongside chronic care management?
Medicare allows RPM to be reported in the same month as care management services such as 99490. Time counted toward one service cannot be counted again toward the other.
Can 99454 be reported with remote therapeutic monitoring codes?
No. Medicare does not allow RPM and remote therapeutic monitoring to be billed for the same patient in the same period. Choose based on whether physiologic or therapeutic data is being monitored.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
