I went to the hospital today to pay 152 yuan, using the Yuhuan County Personnel Labor and Social Security Bureau medical insurance card, they said they need 400 yuan to bottom out before reimbursement

It has nothing to do with how much money is on the individual account of the medical insurance card.

Everywhere in the social security health insurance reimbursement will set a starting standard, more than the starting standard after the expenses can be reimbursed proportionally.

Taizhou city stipulates that the starting standard for outpatient services is 400 yuan, and the annual cumulative amount of credit card swipes below the starting standard for outpatient services will be borne by the individual, and it is only after the cumulative amount exceeds the starting standard that reimbursement will be made on a pro rata basis.

Your case is that you can't be reimbursed because the annual accumulated expenses are within the starting standard of 400 yuan. After you have accumulated more than 400 yuan in the current year, you can enjoy the proportional reimbursement.
