That would be for the first visit. I'm sure Masons first one was about $275. The next visits will be anywhere from $60 - $95 depending on the length of them.

The good news is (I hope it's good news for you ) depending on if you've reached the medicare safety net you can get most of it back. eg Masons most recent ped visit was a $95 one of which we got back $83.70. If not then you have contributed a hefty chunk toward the safety net and you will be closer to it for later on in the year.
(If you get FTB A & B your safety net should only be around $520 worth of out of pocket which you should be quite close to after having a bub )

Hope you can get for help with the reflux!
