Why this was flagged
Medicare paid far more per patient than peers
In 2021 this provider was paid $24,900 per patient, against a typical $16,388 for the same kind of provider in NH. A genuinely high-need patient mix can explain some of this, but extreme per-patient billing is a classic upcoding and phantom-patient pattern.
