1. Unless otherwise provided for by this Regulation, an insured person travelling to another Member State with the purpose of receiving benefits in kind during the stay shall seek authorisation from the competent institution.

An insured person who is authorised by the competent institution to go to another Member State with the purpose of receiving the treatment appropriate to his/her condition shall receive the benefits in kind provided, on behalf of the competent institution, by the institution of the place of stay, in accordance with the provisions of the legislation it applies, as though he/she were insured under the said legislation. The authorisation shall be accorded where the treatment in question is among the benefits provided for by the legislation in the Member State where the person concerned resides and where he/she cannot be given such treatment within a time limit which is medically justifiable, taking into account his/her current state of health and the probable course of his/her illness.

In this case, for the purposes of paragraph 1, the institution of the place of residence of the members of the family shall be considered to be the competent institution.]
