Why this was flagged

Elevated
Suite stacking

Many providers in separate suites of one building

This building hosts providers registered across 3 different suite or unit numbers, a pattern seen when shell agencies are set up side by side.

Shared address

3 providers share this street address

This address is the registered location of 3 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.

Moderate
Owner cluster

Owner is tied to 6 providers

An owner or managing party of this provider (EMMALYN V ALCANTARA) is listed on 6 separate Medicare enrollments. Chains are legal, but rapid multi-entity accumulation is a common structure in healthcare fraud cases.
