In 2022, I had a basic health insurance policy with a deductible (franchise) of 300 CHF starting from January. However, due to exceptional circumstances (which I cannot disclose for privacy reasons), I requested my insurance company to increase my deductible to 2500 CHF in September, and they agreed. Consequently, my deductible for September to December 2022 was 2500 CHF, resulting in lower premiums compared to the 300 CHF deductible for those three months.
Recently, I received a bill from my health insurance company requesting payment for the premium difference for those three months. They stated that the government informed them that “by law they are not allowed to change the deductible of basic health insurance during the year.”
My question is: Is there indeed such a law? While I understand that insurance companies are not obligated to change the deductible mid-year, does the law also prevent them from doing so as a favor upon my request?
