Kernrechtsfrage
Whether the clinic stay was hospital treatment or ambulatory treatment under health insurance law
Extrahierter Entscheid
A stay of less than 24 hours can still be hospital treatment if an overnight bed was occupied because of the treatment; duration alone is not decisive.
Extrahierte Begründung
The distinction depends on the nature of the treatment and, for stays under 24 hours, on whether overnight accommodation resulted from the medical intervention. Here, surgery under general anesthesia and an overnight stay supported hospital treatment.
