In some cases, yes:

• Short-term visitors (less than 1 year) can use international health insurance instead of German insurance.
• Freelancers and remote workers can opt for international plans if they are not bound to German social security.
• Company employees on foreign assignments can use international group plans instead of national insurance.

However, if you plan to stay in Germany long-term, you will likely need to switch to German public or private health insurance.
