Can Chenghai young women's health care be reimbursed by social security?

You can't. Chenghai young women's health care belongs to some private maternal and child health care institutions, not public hospitals. If your social security type is basic medical insurance for urban workers or basic medical insurance for urban residents, then you can only provide medical services and reimbursement in public hospitals and contracted medical institutions. Private maternal and child health care institutions are generally not covered by social security reimbursement.
