We got a bill yesterday from a heart procedure dd had in November 2016. The total was $22K+ before any insurance. However it showed us owing about $2500. I thought that was high considering all the tests she had had earlier in the year. In fact, I thought it should have been about $0. So I called the billing office immediately and spoke to a very helpful lady named Dawn. She put me on hold while she looked into it. Apparently they billed Medicare, which dd has due to disability. However they did not bill Blue Cross. Dawn came back on the line to tell me she submitted while I was on hold! Thankfully I got someone with a brain who is also courteous. She said we would get a revised statement after BC has processed the claim. Be sure I wrote all this down on that statement including her name and the date in case we get a call.
