College students studying in other provinces can choose to pay medical insurance at their domicile. This is because the medical insurance system implements the principle of unified management and cross-regional mutual recognition, so that people can enjoy medical security in different regions. If college students go to school in other provinces and choose to pay medical insurance at the place where they are registered, they can ensure that they can enjoy the corresponding medical insurance benefits when they seek medical treatment. This policy arrangement is helpful to facilitate the medical security of college students during their study in different places, and also conforms to the overall operating mechanism of the medical insurance system.
