Why this was flagged

Elevated
Extreme per-patient billing

Medicare paid far more per patient than peers

In 2020 this provider was paid $32,992 per patient, against a typical $15,480 for the same kind of provider in MA. A genuinely high-need patient mix can explain some of this, but extreme per-patient billing is a classic upcoding and phantom-patient pattern.
