If I use the system of direct payment of Childbirth and Childcare Lump-sum Grant to medical institutions and the cost of childbirth is 400,000 yen, what happens to the difference of 100,000 yen?

The difference of 100,000 yen will be paid to the insured person after the Health Insurance Society receives the claim for delivery expenses from the medical institution.

The insured person does not need to complete any application procedures.
