Why this was flagged

Critical

Billing far above peers

Medicare paid this provider far more than its peers

In 2024 Medicare paid this provider $39,731,492, against a typical payment of $899,466 for the same kind of provider that year. High volume can be legitimate, but extreme outliers are where billing fraud shows up.

Moderate

Shared address

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.
