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.

Owner is tied to 30 providers
An owner or managing party of this provider (THOMAS KNOBLACH) is listed on 30 separate Medicare enrollments. Chains are legal, and most are ordinary business — this is background context, not a fraud indicator on its own.
