I delivered in Kandang Kerbau Hospital under TPS (Private Suite) It's like private so I may not be able to help you much regarding the subsidized system from what I understand in Kandang Kerbau Hospital if it's subsidized patient, where you see the doctors in the clinics other than TPS basically is the same system as NUH where you see a random gynae..
The minute you request to see a particular gynae, you are considered fully paying patient.
At TPS, same gynae all the time, scan every visit, short waiting time, but there is NO package offered, took a A1 ward, by C-sect, if you want more info then I go dig up the bill.
Just trying to offer what I know, might not help as much but that's what I know. Maybe soon more mummies with the same scenario will contribute.
