Does it matter the order or placement of V58.11, versus the cancer diagnoses? We have some payers that reject our chemo claims when V58.11 is primary. It is a system issue, and they aren't able to match the drug with an approved cancer dx, so the system denies, stating no auth or not covered. I am trying to work with our coding department to get some documentation to show that we can move this dx to the 2nd, 3rd, or 4th placement. They insist that the "reason for visit" is to receive chemo, so this has to be primary. This is causing a TON of needless appeals. Any suggestions? Any documentation? HELP!
