<<Disclaimer: Verify this information before applying it to your situation.>> I am trying to decide whether it is worth to spend $800-900 to have a gastroscopy done by a doctor who is very knowlegeable about CD but, alas, out-of-network. The alternative would be to go with another doctor who's in the network, and then maybe have the out-of-network doctor examine the results. I am a diagnosed celiac, I'm having the gastroscopy as a check (still not absorbing calcium and vitamins). So my question is: has anybody had some negative experience with gastroscopy due to the choice of one doctor rather than another? or is it a routine procedure, like a blood test, that can be done practically anywhere?
