"They will always insist on collecting an advance payment even if you are covered by insurance. The usual trick is to charge you $700+ for a "Cone CT" scan that is unnecessary and generally not covered by your insurance. (I have BlueCross dental PPO who generally covers everything). In my case, for initial exam (usually covered at 100% by BlueCross), they insisted on collecting an advance payment of $355. Once I paid, they charged me $700+ for "Cone CT" and have not refunded the money. They subjected me to unnecessary radiation despite my telling them that I am a "cancer survivor" and didn't want the scan. For Dr. Stuparitz, it appears that making money takes priority over a patient's well being. Sad! By posting my experience, I hope I can save others from being fleeced. Even if I can save one person, I will consider my $355 loss had some redeeming value. Thanks!"

"I regret seeing him since he's very expensive & charged me $500 more after surgery saying it was a difficult surgery. The Billing Dept. is terrible!!!! They gave me a very hard time & would not send my bill to my Ins. Cos. at first. The lady I talked to several times was his wife & she was very rude & unprofessional DO NOT GO TO HIM!!!!"
