Are healthcare and health insurance expensive in Heidelberg?

"Healthcare and health insurance in Heidelberg can be expensive, depending on the type of coverage and services required. Generally, public health insurance is available to those who are employed or studying in Germany, and is usually subsidized by employers or the government. Private health insurance is also available, but can be more expensive. In addition, some medical services may not be covered by insurance, and may require out-of-pocket payment," remarked another expat who made the move to Heidelberg, Germany.
