RKI data show documented mental disorder diagnoses rose from 33.4% in 2012 to 37.9% in 2022.

The Claim

A 2025 Robert Koch Institute report found that in Germany the share of adults with statutory health insurance outpatient claims who had at least one documented mental disorder diagnosis (ICD-10 F00–F99) increased from 35.0% in 2012 to 40.9% in 2022.

The Short Version

The RKI did report an upward trend, but not the one stated here. For 2012–2022, official RKI sources report 33.4% rising to 37.9%, while the 40.9% figure belongs to 2024 in a different RKI indicator series. The claim therefore combines real RKI numbers from different years and datasets, which materially changes the factual takeaway.

Caveats

  • The claim conflates two RKI data series: the 2012–2022 trend report and a broader adult administrative-prevalence indicator.
  • The 40.9% figure is linked to 2024, not 2022; using it as the 2022 endpoint is a substantive error.
  • The underlying source attribution is imprecise: later 2025 presentations may discuss the topic, but they do not make the claimed 2012–2022 finding.
