Definition
A supplier of a personal emergency response system (PERS), which is an electronic device that enables a patient to receive emergency assistance when needed. The PERS is one of two different methodologies of notification: (1) where the patient summons emergency assistance themselves directly through the device or (2) emergency assistance is summoned through secure activation by the caretaker/guardian, which sends the device location to emergency responders.

Using 333300000X
The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
