Actually, you get this. Critical services are provided to all patients, regardless of nationality. All EU health insurances are accepted for urgent treatments. There's some time limit after which you'll need to register and get German insurance, but well, the way the system is set up (different payments and different paid-for treatments in the various countries), this is the only way things can currently work. It would be better if it was all unified across the EU, but that will take some time.
