Articles 50 and 51: health data holders (bodies in healthcare or care, product and service developers for health, wellness-app makers, health researchers, mortality registries and Union bodies that process such data as controllers or control a product's data) make available the categories in Article 51(1): EHR data, health determinants, aggregated healthcare needs and spending, pathogen data, administrative and claims data, genetic and genomic data, other omics, device-generated data, wellness-app data, professional data, population and medical registries, clinical trial and study data, other device data, product registries, research cohort and survey data after first publication, and biobank data. Natural persons and microenterprises are exempt unless national law says otherwise (notified by 26 March 2029); Member States may add categories and set stricter safeguards for genetic, omics, wellness and biobank data.
