1) New card, new claim.
2) Confirmation can mean paying or not paying provisional, but it isn't required for the claim itself (see Randy's cite).
3) Consider not reissuing a card unless there are compelling reasons why. I'd guess it's her kids or stored info being used. There is a cost in the claim amount paid as well as the time to do these claims.
