BE AWARE. Dr. Wintersteen's employees do not hesitate to assure a patient that they do work with his/her medical insurance while the doctor, in fact, is an out-of-network provider. The combination of the affirmative statement 'we work with your insurance' and unmentioned 'out-of-network' status is merely unheard-of in a normal, non-fraudulent practice. They do not tell the patient that the doctor is an out-of-network provider, as if it was insignificant, or they just never knew what that means. Yet, it seems they do whatever they can to delay the processing of the first insurance claim, so the problems would not become obvious as long as possible. The claim for my surgery was properly filed with almost 2-month delay despite the numerous reminders.
