Why this was flagged
Medicare paid far more per patient than peers
In 2022 this provider was paid $36,861 per patient, against a typical $17,106 for the same kind of provider in IL. A genuinely high-need patient mix can explain some of this, but extreme per-patient billing is a classic upcoding and phantom-patient pattern.
