Congratulations on your pregnancy!
I am starting to worry about my costs now, I am seeing a private ob and i was charged twice as much for my first appointment! (I did have an internal scan to find out my due date though, so maybe thats why)
I checked it all out with Medicare and also the midwife who sat down with us before our first appintment explained it all really well. We get a fair bit back from Medicare, we also have private health insurance. At the hospital we had to pay a deposit of $200, where patients with no private cover have to pay $4000, which is huge for a deposit IMO. At 20 weeks I have to pay the ob $1500 which is not claimable from medicare, but after that I get most of the actual birth cost back. And my excess is $250 for hospitalisation. I didnt have to pay for my blood tests as it was just done at a local pathology clinic, but I do pay for all my ultrasounds, and a standard fee for each appointment.
