Someone gets to have a bad day... not me, though!

The anesthesia bill was clearly coded wrong. The very nice customer service rep I spoke with says they will re-code it, resubmit it to the insurer, return the payment the insurer already made, and "generate a new responsibility" for me.

Query: the CSR was able to pull up my diagnosis on the computer and see that it didn't match the type of surgery for which I was billed. Why couldn't any other parts of The System do that? It shouldn't take a programming genius to restrict the list of valid codes based on the diagnostic code.
