Are healthcare and health insurance expensive in Dortmund?

"Healthcare and health insurance in Dortmund can be expensive, depending on the type of coverage and services needed. Generally, public health insurance is required for those living and working in Germany, and the cost of this insurance is based on income. Private health insurance is also available, but it can be more expensive than public insurance. Additionally, out-of-pocket costs for medical services can be high, and some services may not be covered by insurance," mentioned another expat when asked about moving to Dortmund, Germany.
