Calls for a European Health Union apparently challenge long-standing beliefs that national healthcare system organisation is a Member State competence. Interaction between Member State and European Union (EU) levels therefore fundamentally requires reflection in the design, overall structure and legal basis of any European Health Union. Article 168(7) Treaty on the Functioning of the European Union (TFEU) provides the current version of the seemingly limited EU competence with regards to national healthcare system organisation and has received surprisingly little attention thus far. On the one hand, within the wider EU health competence ‘web’, Article 168(7) TFEU constrains EU adoption of measures incentivising Member States to use particular treatments or to increase intensive care units in response to COVID-19. On the other hand, Article 168(7) TFEU is challenged by the perceived influence of Country-Specific Recommendations issued in the context of the European Semester on national health policies. This opinion piece provides an original assessment of Article 168(7) TFEU to argue that Treaty change to redress the balance between EU and Member State competence regarding national healthcare systems may be uncalled for given both the flexibility afforded by the provision and the complexity and diversity of Member State healthcare systems.
