Ma ma ma myyyy seroma

I had so many complications with bypass, I don't think anything could freak me out now! I am on meds for anxiety already. It's something I deal with. The shrink I had to see for bypass took me off of them before I could get approved. He said I was just depressed because I was fat and that I'd be okay. BAD MOVE. It took my primary care physician and me months to get me back on track.

I need to have an ultrasound and new drain out in due to my seroma after having a tummy tuck 4 weeks ago. My question is, did your insurance cover it? My doctor is telling me that I need to use my insurance for this procedure. 

Thank you!
