Without prejudice to any more favourable provisions in paragraphs 2 and 2a of this Article, Articles 17, 18(1), 19(1) and 20(1) shall also apply to benefits relating to accidents at work or occupational diseases.

A person who has sustained an accident at work or has contracted an occupational disease and who resides or stays in a Member State other than the competent Member State shall be entitled to the special benefits in kind of the scheme covering accidents at work and occupational diseases provided, on behalf of the competent institution, by the institution of the place of residence or stay in accordance with the legislation which it applies, as though he/she were insured under the said legislation.

The competent institution may not refuse to grant the authorisation provided for in Article 20(1) to an employed or self-employed person who has sustained an accident at work or has contracted an occupational disease and who is entitled to benefits chargeable to that institution, where the treatment appropriate to his/her condition cannot be given in the Member State in which the person resides within a time limit which is medically justifiable, taking into account his/her current state of health and the probable course of his illness.

Article 21 shall also apply to benefits falling within this Chapter.
