How long did kkh take to send the final bill?

I am just curious to know how long KKH takes to send you the final bill after you discharge from their wards? Recently gave birth under B1 at KKH paid the deposit during pre admissions but am curious to know if there will be additional charges and when they will send us the final bill. Because hubby recently had his medisave deducted of only 1k plus from kkh but total deduction for my B1 stay should be over 4k.#pleasehelp #advicepls #pregnancy
