Kernrechtsfrage
What is the dispute scope: only further treatment after the initial six months or also the already paid first half-year?
Extrahierter Entscheid
Only the continuation of therapy beyond the initial six months was in dispute; the already paid first half-year was not part of the case.
Extrahierte Begründung
The earlier payment was based on a formless, final cost approval. The insurer had not validly reopened or revoked that payment; its later decision concerned only further coverage from June 2008 onward.
