Like most of the non-student visas, you most likely need to show a proof of health insurance that will cover your entire stay for your visa application.
X-patrio presents 50+ years insurance expert DR-WALTER’s EDUCARE 24 insurance products. Each and every insurance product X-patrio presents has coverage that satisfies visa requirements. Moreover, EDUCARE24 is a German insurance which has no risk to be refused or rejected from visa authorities.

If you are studying at a German University but will do a language course before your University studies:
Your visa application states that you must be covered your whole stay, or it will be rejected. You must apply for Private Health Insurance first. This will cover you as a language student. Once you begin your studies, you can cancel the Private Health Insurance and then join the Public Health Insurance plan.
