In 2025, Techniker Krankenkasse will increase its additional contribution rate to 2.45%, up from 1.2% in 2024. This rise is attributed to increasing healthcare costs and a lack of financial reserves. The average additional contribution for 2025 is set at 2.5%, prompting expectations of further increases among other health insurance providers. Health Minister Karl Lauterbach highlighted inefficiencies in the system, indicating that reforms are necessary. The BKK Dachverband predicts contributions may rise even higher than government estimates, marking the largest increase since the free choice of health insurers was introduced in 1996.
