I'm going to guess at that country being Germany. There's an edge case where if you have the "state" insurance, then leave the country, have private health care abroad, and then move back, the health insurance situation gets difficult. You're no longer allowed to get the "state" health insurance, and must go private. But the private ones can basically rack you for the maximum amount if you're old enough, so you can end up not being able to afford the insurance. At that point, you're now breaking the law, as I understood it, because you're without health care insurance in a country that mandates it by law.
