Künstlersozialkasse - What is the KSK? What kind of health insurance makes sense?

Individual expert consultation with Philipp Schmucker, Medien-Finanzservice.

What is the KSK? How can I reduce my health insurance costs by up to 50% with the help of the KSK? What gaps exist and how can these be covered affordably? What additional benefits do I receive from the KSK? Is it possible for me to join the KSK? What documents do I need for the application?
