Precautions for binding a baby's medical insurance card to a parent's medical insurance card are as follows:

1, the child's personal information must be accurate. If the child's personal information submitted by parents is incorrect, the child's medical insurance card cannot be bound to the parent's medical insurance card;

2. It is a prerequisite for the children's medical insurance card to be bound to the parents' medical insurance card. If the child does not apply for medical insurance in advance, the child's medical insurance card cannot be bound to the parents' medical insurance card;

3. When the child goes to see a doctor to pay for medical expenses or goes to a designated pharmacy to buy medicine to pay for medicine, parents should never disclose the payment password to avoid unnecessary losses.

4. The specific handling methods and requirements in different regions may be different. It is suggested to consult the local social security service center for detailed information and submit the required materials as required in order to successfully complete the binding procedures;

To sum up, children's medical insurance costs and parents' medical insurance costs can be paid together after binding. If the child goes to the hospital for medical treatment, he can directly swipe the child's medical insurance card, and the medical expenses will be directly deducted from the parents' personal medical insurance account.
