Remote Physiologic Monitoring codes involve collecting physiologic patient data to guide treatment plans, according to the CMS 2021 final rule. The main differences between RTM and RPM codes are the types of data collected and how. RTM codes allow for monitoring “non-physiologic data” focusing on patient data through signs, symptoms, and functions of therapeutic response (e.g. therapy adherence and response). RPM codes focus on physiologic data generally understood to be parameters generated by the body (e.g. ECG, blood pressure, etc.) that are detectable by a signal acquisition medical device/system. RTM and RPM data can both be digitally uploaded. For both sets of codes, the device used must meet the FDA definition of a device as described in section 201(h) of the Federal Food, Drug, and Cosmetic Act (FFDCA). Hero meets this definition.
