I had an MRI done on my hip a few years ago. Since I had a $5000 deductible I decided to pay cash and negotiated with the doctors billing department for $1200. When the bill came it was $2200. I fought with the billing department, they couldn't give me a good argument, basically called me a liar and said they wouldn't take a penny less than $2200, even if it meant a payment plan. I filed it with my insurance and although they didn't pay a penny they got the bill down to $1050. It makes no sense. I had to file a claim that will cause my premiums to go up and the doctor ended up getting less than I would have happily paid. It just seems so ass backwards how the system works.
