Kernrechtsfrage
Whether additional interdisciplinary medical evidence had to be ordered.
Extrahierter Entscheid
No further neurological or neuropsychological assessment was required; the existing hand-surgery report was sufficient.
Extrahierte Begründung
The court found the specialist report by Dr. med. B. fully probative and adequate to assess functional limitations and residual work capacity, so the duty to investigate was not breached.
