If there is no comparable price for domestic patients, Article 4(4) places an obligation on providers to charge a price calculated according to objective, non-discriminatory criteria.
Jekk ma jkun hemm l-ebda prezz komparabbli għall-pazjenti domestiċi, l-Artikolu 4(4) jobbliga lill-fornituri li jitolbu prezz ikkalkolat skont kriterji oġġettivi u nondiskriminatorji.
