Kernrechtsfrage
Whether the insured's health had materially changed since the last substantive review.
Extrahierter Entscheid
No materially changed health situation was proven with the required degree of probability; the 2016 expert report remained decisive.
Extrahierte Begründung
Later hospital and treating-doctor reports did not reliably demonstrate a lasting deterioration. The recent hospitalizations were temporary, and the treating physician's assessment was insufficiently substantiated.
