Changing your public health insurance (Gesetzliche Krankenversicherung) in Germany is easier than many people think. Whether you’ve found a better service, moved to another state, or simply want lower premiums, switching your provider can save you money and improve your healthcare experience.

📌 Understanding Public Health Insurance in Germany

Germany has one of the world’s most comprehensive public healthcare systems, covering about 90% of residents. Public health insurance is managed by over 90 approved health funds (Krankenkassen) such as TK (Techniker Krankenkasse), AOK, Barmer, and DAK. While all public providers offer similar basic coverage, service quality, extra benefits, and additional contributions (Zusatzbeiträge) can vary. This makes comparing and changing providers worthwhile.

📅 When You Can Change Your Public Health Insurance

You can usually switch your Krankenkasse if:

• You’ve been with your current provider for at least 12 months.
• Your provider increases its additional contribution rate.
• You’re switching jobs and your new employer requires a different insurance provider.
• You’re moving to a different region or state.

Since 2021, the process has been simplified—no need for a cancellation notice to your old provider; your new provider handles it for you.
