If you have insurance and plan on using it, I think your first step is to find an Ob that works for you. There are so many in HK, it may be a good idea to tell us where you are living and we might be able to recommend some close by. Then that Ob can recommend a hospital where they deliver. Most Obs deliver at 2 or 3 hospitals so you are likey to get a small choice, and I haven't heard any horror stories about any particular hospital. I would think that avenue would be easier then finding a hospital and then trying to locate a Ob that delivers there that you like.
To give an idea of costs, for the total number of Obstetrician visits including the standard blood tests, scans etc were approximately $30HKD. I then delivered in Matilda, private room, and all costs including delivery, Obstetrician, Pediatrician, tests in hospital etc (all the standard stuff) cost us $100HKD. I had a smooth pregnancy and delivery, and no complications with baby after delivery. It was a standard Vaginal Birth with no drugs or epi (so no Anesthetist costs) so I guess it is fair to say that for this hospital and Ob (Dr Alex Doo) this would be your basic costs. I was not aware of any 'package deals' available with any Obs besides the ones described earlier with Grace Cheung and Lucy Lord. Good luck and congratulations on your pregnancy.
