Can the baby use the mother’s medical insurance card? The baby can use the mother’s medical insurance card. According to medical insurance regulations, newborns can use the mother's medical insurance, and the reimbursement of medical expenses incurred is combined with the mother's. While parents have fulfilled their obligation to pay, they also have the right to use medical insurance pooled funds for treatment. Naturally, children can also use their parents' medical insurance when they are born. Moreover, according to the legal reimbursement standards, if a newborn is hospitalized when he is born, he can be reimbursed by supplementary medical insurance. If a female employee participates in social security in the year of childbirth, the newborn can be automatically included in the medical insurance from the date of birth and enjoy medical insurance benefits along with the female employee's social security. However, if your child is sick and hospitalized, you can only use your own medical insurance card and social security for reimbursement. If the child has not yet applied for medical insurance, he or she can be directly bound to the parents' medical insurance. After binding, you can directly use your parents' social security card to see a doctor in the outpatient clinic, and the personal account balance of your parents' social security card will be deducted. Children can use their parents’ medical insurance cards and only use the money from their parents’ personal accounts. If the parents have medical insurance, the baby can use the parents' medical insurance. However, adults still need to apply for a medical insurance card for the baby in time. After the application is successful, the baby can be reimbursed with the medical insurance card if he gets sick. Otherwise, all expenses need to be paid out of pocket.
