I had an HSG a few weeks ago. I asked the hospital for the information to find out the cost ahead of time. The gave me the procedure code, and told me to call my insurance. They told me there was a facility fee of $70, a doctor fee of $70, and possibly a fee to read the test, but that would be "$100 at the absolute most." The hospital called me and told me later that the cost would be $1050. I told them what the insurance said, and the woman said she would put a note in the chart. Today I got a bill for $1050. I looked at my insurance website, and it looks like the original bill was for $2600, the allowed amount was $1200, insurance paid $150, and I supposedly owe $1050. I looked up the Healthcare Bluebook fair cost of the procedure, which is $140 for my area. Has anyone else successfully gotten a charge decreased? I'm going to call them tomorrow, but what is the best way to talk to them to get the cost to be more in line with what I was told?
