Aetna Clinical Policy: Automated Ambulatory Blood Pressure Monitoring – Rules for ambulatory blood pressure monitoring, which is different from "home" blood pressure monitoring. Useful to know when thinking of connectivity in the California Healthcare Foundation project work. Because health plans and CMS already pay for this type of monitoring, there’s precedent for looking at home blood pressure monitoring. This type of monitoring (ambulatory) pays for itself because it can establish the presence of “white coat” hypertension, which is high blood pressure that only occurs in the doctor’s office. In that situation, it’s better for the patient not to undergo treatment, which saves them (and the system) time and money in unnecessary health care.
