Kernrechtsfrage
Whether the insurer could revoke its prior full payment and demand restitution of CHF 1,708.
Extrahierter Entscheid
The insurer could not revoke the initial payment because it did not show that the full coverage decision was manifestly erroneous.
Extrahierte Begründung
Reconsideration of a final administrative decision requires a clear error and notable importance. The record did not establish whether the treatment was ambulatory or hospital-based, so the legal basis for applying the lower cantonal tariff was not sufficiently clarified.
