Refunds for credit card payments during hospitalization are generally made after the discharge procedures are completed, and the hospital will refund the money to the original credit card. After the cardholder pays the hospitalization fee with a credit card, the excess amount will be directly refunded in cash when the patient is discharged from the hospital. If some small hospitals are unable to refund cash, the excess balance in the settlement needs to be returned to the original card, and the cardholder needs to take the credit card to the hospital's financial department to apply for a refund. It is recommended that cardholders do not use the hospital's refund of hospitalization fees to cash out a large amount of credit, because it is very likely to be frozen by the bank on the grounds of transaction risk. Just pay the hospitalization fee appropriately and do not transfer more money to the hospitalization fee.
