Techniker Krankenkasse

The Techniker Krankenkasse (TK) is the largest health insurance organization in Germany, providing general insurance as required by law compared to private health insurance companies. The TK is a Körperschaft des öffentlichen Rechts, meaning it's legally not a public company but its organization is defined by the Sozialgesetzbuch Fünftes Buch federal law. Since September 2016, the TK is also branding itself as Die Techniker.
