I've been keeping a running tally and I'm about $1000 out of pocket so far - but $400 of that is the gap on my PMF not covered by Medicare. That also includes my 19 week scan. I have reached my medicare threshold now so my OB visits are now only costing me $11 (he charges $81 per visit) so the rate at which I'm racking up expenses has slowed down now somewhat.

My OB does not charge a gap for delivery so I only have to pay him for pregnancy visits.

There will probably be out of pocket fees for an anesthesist (IF I have an epi) and pediatrician while we are in hospital.

I'm expecting to be out of pocket around 2K all up by the time it's all said and done.
We have top hospital cover with HCF.
