Why this was flagged
Medicare paid far more per patient than peers
In 2023 this provider was paid $15,224 per patient, against a typical $7,203 for the same kind of provider in TX. A genuinely high-need patient mix can explain some of this, but extreme per-patient billing is a classic upcoding and phantom-patient pattern.

2 providers share this street address
This address is the registered location of 2 separate Medicare-enrolled providers. Legitimate causes exist (shared medical office buildings, management companies), but dense clustering of billing entities at one address is a known fraud pattern.
