The following information provides an overview of the collection and processing of your data and the rights related thereto.

  • Why do we process your data, and on what legal basis?

    AOK, as a provider of solidarity-based health and care insurance, has the task of preserving, restoring or improving the health of its policy holders, as well as providing assistance to those in need of care who rely on solidarity support owing to the level of their need for care.

    The benefits and other expenditure are financed by collecting contributions from employers and members.

    In order to fulfil these statutory tasks, AOK processes the data required for this purpose. This data is collected from you on the basis of statutory duties of cooperation (see, e.g. Section 60 et seq. SGB I) or on the basis of consent. AOK also receives data from third parties in accordance with the SGB (e.g. from your employer or care providers). Your failure to cooperate could adversely affect you when it comes to the provision of benefits (refusal or withdrawal of benefits).

    For health insurance, the legal basis for data processing is Art. 6(1)(e) and (3)(b) and Art. 9(2)(b) and (4) EU-GDPR in conjunction with Section 284 of the German Social Code, Book V (SGB V), and for nursing care insurance it is Section 94 of the German Social Code, Book XI (SGB XI).
