Employees trained in billing fraud? Violent allegations against a large eye doctor chain. If these practices were actually used, they could possibly even be criminally relevant, say lawyers.

The affected chain is a leading player in the healthcare industry. In the report, NDR journalists quote from an online seminar that was allegedly led by one of the company's co-founders. For example, the seminar leader encouraged the participants to charge the maximum rate for cataract operations. This could result in around 250 euros more being billed than usual. With a different billing number, around 1000 euros more could be generated.
