Questione giuridica chiave
Whether the insurer's 8 May 2002 letter denying benefits was a formal decision or an informal disposition.
Decisione estratta
The letter was not a formal decision because it was neither designated as such nor accompanied by appeal instructions; it belonged to the informal procedure.
Motivazione estratta
Under the ATSG/UVG scheme, a formal decision is required for significant benefits or where the insured disagrees; absent decision form and appeal notice, the communication is treated as informal.
