Are healthcare and health insurance expensive in Hannover?

"Healthcare and health insurance in Hannover can be expensive, depending on the type of coverage and provider. Generally, public health insurance is more affordable than private health insurance, but it may not cover all medical expenses. Private health insurance can be more comprehensive, but it is usually more expensive. Additionally, some medical treatments may not be covered by either public or private health insurance, and these can be costly," remarked another expat who made the move to Hannover, Germany.
