Why this was flagged
Medicare paid far more per patient than peers
In 2020 this provider was paid $21,693 per patient, against a typical $13,008 for the same kind of provider in OK. A genuinely high-need patient mix can explain some of this, but extreme per-patient billing is a classic upcoding and phantom-patient pattern.
