Every day, statutory health insurers receive tips. Anonymous reports. Audit findings. Billing irregularities. And on the other side of the desk: teams that, according to a PwC study, consist on average of around three full-time staff to handle all of it.
The imbalance is obvious. The consequences are serious.
The Real Problem Is Not a Lack of Commitment
Fraud investigation units at statutory health insurers do rigorous work. The problem is structural.
A single preliminary investigation to establish reasonable suspicion takes, depending on case complexity, four to eight hours of pure working time. Billing data must be reviewed, legal statutes must be assessed, a formal referral to the public prosecutor must be drafted. All of this in compliance with the German Criminal Code (§§ 263, 266, 299a/b StGB) and the statutory framework for fraud investigation in public health insurance (§197a SGB V).
And when that referral arrives at the prosecutor's office as a disorganized stack of documents, the case is frequently closed for lack of sufficient initial suspicion under §152 para. 2 of the German Code of Criminal Procedure. Not because no fraud occurred, but because the documentation does not hold up.
Germany's statutory health insurance association (GKV-Spitzenverband) last estimated the damage caused by misconduct at over €200 million. The AOK group alone recovered approximately €42.8 million in the last reporting period. The unrealized potential is substantial.
A New AI Agent for an Underserved Function
We built Ernst. An AI agent designed specifically to support preliminary fraud investigations under §197a SGB V.
Ernst accepts case documents, whether billing data, whistleblower reports, or care records, and automatically runs them through a five-stage decision framework. It identifies phantom billing, upcoding, time anomalies, and unauthorized delegation of medical services. It classifies the relevant criminal statute. And when initial suspicion is confirmed, it produces a print-ready draft referral to the public prosecutor, including a full evidence inventory and all legally required clauses under §459h of the Code of Criminal Procedure.
What previously took hours now takes minutes, including human review and sign-off.
Early Results from the Pilot
Ernst is currently in active pilot deployment with its first clients. Results are still being validated, but the directional evidence is clear.
Data review and fact extraction, which manually takes two to four hours, is completed by Ernst in one to two minutes. The legal indicator assessment, previously up to two hours of research, is reduced to under one minute. Drafting the referral document, which required one to two hours of writing, now takes around two minutes.
Overall time savings per qualified case currently stand at 80 to 90 percent. That means the same team can process substantially more cases, or redirect freed capacity toward the complex investigations that genuinely require experienced judgment.
What Ernst Is Not
This needs to be stated plainly.
Ernst does not replace investigators. It handles the administrative work, not the decision-making. The final legal judgment on any referral under §197a para. 4 SGB V always rests with the human professional. This Pilot-in-Command principle is not simply an ethical position. It is built into the workflow.
For sophisticated fraud networks where physicians, care providers, and pharmacies collaborate deliberately, traditional investigative work and the instincts of experienced case handlers remain irreplaceable. Ernst provides the structured foundation. The rest is human.
Every output is fully traceable. Nothing leaves the system that cannot be explained.
What This Means for §197a Units
More time for real investigative work. Consistent, legally sound referrals regardless of who handles the case. A significantly higher likelihood that a submission to the prosecutor's office will actually result in proceedings being opened.
And one point that is frequently underestimated: the mandatory reporting obligation under §197a para. 4 SGB V carries real liability risk when tips are not processed within appropriate timelines. Ernst turns a compliance burden into a manageable, documented process.
