    Clinical & Coding Specifications

    Clinical Context

    A typical patient is a 68-year-old with congestive heart failure and an implanted remote monitoring device transmitting daily weight and thoracic impedance data. The clinician enrolls the patient in a remote physiologic monitoring (RPM) program; clinical staff review aggregated device data weekly and the billing clinician performs at least one real-time interactive communication with the patient or caregiver each month to review symptoms, medication adherence, and device findings. The service includes structured review of physiologic data, documentation of clinical interpretation, and adjustments to the care plan (for example, diuretic dose changes or urgent evaluation) based on trends. Each additional 20 minutes of professional or clinical staff time spent managing the RPM data during the month is reported with 99458 as an add-on to the primary RPM service.
