What is LTC = long term care (PVN = Pflegeversicherung)
Long-term care insurance was introduced as an independent branch of social insurance on January 1, 1995. It is a mandatory insurance for everyone with public or private health insurance. Everyone who is insured by the public health insurance is automatically insured in the social long-term care insurance. Those with private health insurance must take out private long-term care insurance.
The benefits of social long-term care insurance are financed by contributions, which employees and employers pay mostly equally. When and which benefits those in need of care receive from the insurance depends on the duration of the need for care, the degree of care and the type of care. You can find more information on the website of the federal ministry of health (in German).
