what in tarnation

Marissa
So I was diagnosed two weeks ago with an ovarian cyst and it was recommended I get an ultrasound. I got a phone call today from the office as a courtesy saying this ultrasound was going to call 190 dollars. With my insurance. Why?! Is it not considered preventative care since I have a history of ovarian torsions? I have really great insurance too so this super confused me. 
I ended up cancelling the appointment because I can't afford that at all. I guess I'm just gonna sit here and hope I don't die or something. 😒
