I had something kind of similar happen. Called my NorthShore doctor for a HCG beta (blood pregnancy test), went in for what I thought was just a draw for that. Looked at the bill the next day and was shocked to see a bill for $607. Looked carefully at the
lab and saw that my doctor had ordered a CBC, T4 Free, and TSH without telling me. The bill would have only come to $214 had it been just the pregnancy test, which was all I requested or consented to. Insurance paid for it all.
I love my doctor and he's pledged to make sure to tell me about tests beforehand in the future, but had I been paying for this out of my own pocket, I probably would have contested the bill.
If I were you, I would look into contesting the bill. The NorthShore Patient Rights and Responsibilities (http://www.northshore.org/UploadedFiles/PatientRights_English.pdf) say that you have the right to consent to and participate in your treatment. If you
didn't consent to these tests, then you didn't consent to being billed.
And from now on, whenever anyone wants blood, urine, or any other sample from you, be sure to ask what tests they're performing. If you go to one of the NorthShore blood labs, ask when you check in what tests they have orders for. You can then cancel any
tests you don't want to do. My doctor ordered another CBC and TSH at my first OB appointment on February 4th, and I canceled them when I went to the lab because we had just done the other CBC and TSH on January 12th. I have to draw the line at testing for
those things more than once a month.
