The Health Care system is a vampire!

Let's have a review. I have recently undergone knee surgery that turned out to be a little more than expected. Weeks of physical therapy. A colonoscopy and CT scan for scar tissue in my abdomen from, now remember this next phrase, "MY COMPLETE HYSTERECTOMY." And last but not least a consult with a surgeon concerning the same issue. As you might would guess, what with this tick list of minor health concerns I have received a pile of medical bills thick enough to insulate a small dwelling. I am so thankful for health insurance! I go over each bill with a fine toothed comb to make sure that my insurance company agrees with the doctor's office on what my portion should be before I send out a check. I got the bill the other day from the doctor that I went to for the consult concerning (this is from the chart now), "adhesions due to hysterectomy".....on the itemized statement was a charge for $18.00 for a PREGNANCY TEST!! What? Are you kidding me? Surely this is a mistake, I thought. So, of course, I called the less than stellar employee at the doctor's office. I explained to the girl that my insurance company was being charged for a pregnancy test on a woman with NO uterus! She laughed, and said, "yeah, isn't that crazy, we do one on every one that comes in." Well, heck yeah ya do. It cost's sixty-seven cents to do one and then you get $18 dollars for it, that's good business anywhere you check. I said, "so I see how it works, you know you have an agreed upon amount that the insurance company is willing to pay, so you drum up every charge you can possibly come up with and hope in the end you'll get $185.00 of the $2000.00 you charged them. 'I see here where your chart says you've had a tonsillectomy Mrs. Patterson, open up and let's see if they're still gone, yep they're gone alright, that'll be $22.50, add that to the bill Nurse'.......her reply,,,"um, actually, yeah."
I give up!!
