Question juridique clé
Whether the appellant remained entitled to Krankentaggeld from 2016-09-01 onward
Solution extraite
The insurer could not rely solely on the earlier prognosis; it had to clarify the later course of incapacity before ending benefits.
Motifs extraits
The expert report provided only a favorable prognosis. Later medical certificates attested continuous 100% incapacity through 2016-12-16 and created relevant doubt. The insurer therefore breached its duty to investigate by not obtaining updated reports or other evidence.
