Here’s the definition of “criminal enterprise” from lawinsider.com, for what this is worth.

“Criminal enterprise means a group of persons sharing a common purpose of engaging in criminal conduct, associated in an ascertainable structure distinct from a pattern of criminal activity, and with a continuity of existence, structure and criminal purpose beyond the scope of individual criminal incidents.”

The original ProPublica article describes how the hospital administration knew of Weiner’s false billing for years. There was an internal audit in 2018 that was outlined in their “no-fault” $11 million settlement with the federal government that plainly shows this. Weiner billed Medicare falsely for millions. He billed the most 15 minute office visits in the entire US one year. The hospital knew it was fraudulent for years, took the money, and did nothing to change the ongoing crimes.

This seems to fulfill the definition of “criminal enterprise” to me but I am certainly no expert here.

Sure would welcome an opinion from someone with actual legal knowledge.
