Facts

Mr Kohll, a Luxembourg national, asked his health insurance fund for authorisation for his daughter to receive orthodontic treatment from an orthodontist in Germany. Under Luxembourg rules, such treatment would only be reimbursed if it had been authorised in advance. Authorisation was refused, because the treatment was not urgent and could be provided in Luxembourg.

Legal principle

The Court of Justice held that the requirement of prior authorisation was a restriction on the freedom to provide services, because it deterred insured persons from approaching providers of medical services established in another Member State. It could not be justified by the risk of seriously undermining the financial balance of the social security system, because reimbursement was at the same rates as in Luxembourg, or by the need to maintain a balanced medical and hospital service, because it concerned treatment outside a hospital. The protection of public health could not justify it either, because the conditions for practising as a doctor had been harmonised.
