KKH Delivery Deposit

Hi! I am a subsidized patient in KKH, and planning to deliver in ward B2 or B2+. Just a few questions for mummies that recently delivered there. 1) Will there be a cash deposit? How much is the estimated deposit? 2) How much can medisave cover the total hospital bill? Does it include the deposit we placed (if there's any)? 3) In the event that i have to give birth, where should i go in KKH? Delivery suite straight? Or who/what number should i call if my water bag burst, i have contractions etc..? Will they advise me where to go? 4) How much does an epidural cost? Thank you in advance, and apologies if my questions seem silly, im a first time mom here. 😅
