I believe my former gastroenterologist and/or radiologist misinterpreted the ultrasound reading, & thus recommended to remove my gallbladder. The surgery did not occur because I sought a second opinion. And now I seek the refund of the coinsurance I paid while in the treatment of this gastroenterologist (it amounts to less than $700). My former gastroenterologist claims that the stone just passed out (even though I never experienced any symptoms associated with the gallbladder disorder) & the two ultrasound tests were done only days apart. I want to resolve this issue in the small claims court by presenting them the main evidence: first ultra sound report (stating that I have stones) & second (stating that I don't). What are my chances? Do I risk to pay def. attorney fees if I lose ?
