Foshan stopped paying social security in August and paid it in September. Can medical care benefit afterwards?

No, the down payment for medical insurance needs to wait for half a year, and the medical expenses incurred after half a year are allowed to be reimbursed as usual.

For those who participate in medical insurance for the first time, the payment time is assumed to be 1 month, which requires continuous payment for 6 months, and the medical expenses incurred since July can be reimbursed. If the payment is interrupted for more than 3 months, that is to say, the individual is insured to participate in medical insurance, but later the payment is interrupted for more than 3 months, and it takes 6 months to be reimbursed. If you participate in medical insurance within two months after the termination or rescission of the labor contract with the employer, or if the unemployed participate in basic medical insurance within two months after the expiration of receiving unemployment insurance benefits, there is no waiting period for reimbursement and you will enjoy medical insurance benefits from the month of payment.
