Questione giuridica chiave
Whether the appeal was admissible despite the absence of a formal appealable decision by the insurer.
Decisione estratta
The appeal was premature because no decision had yet been issued; only decisions on opposition, or decisions where opposition is unavailable, may be appealed.
Motivazione estratta
Under Art. 56 LPGA, applicable via Art. 1 para. 1 LAMal, judicial review presupposes an appealable decision. Since the insurer had only given a position and was still drafting a formal decision, the filing was manifestly inadmissible.
