I work in Urology and we have patients that come in the clinic that have a personal history of a problem ,such as history of UTI, Kidney stone, cancer , basically all "Z" codes, and the Z codes are the primary and only DX code assessed. Cigna is denying all of the Z codes as cannot be used as a primary DX code. When we researched them, the only documentation we can find is that the codes cannot be used as primary for Inpatient ONLY. I'm stumped about what to do since the patient comes in for a yearly follow up only. I've reviewed the HPI and the only thing discussed is previous problems that they are not currently having. They are only under surveillance. Any suggestions? Has anyone found a Cigna policy that addresses Z codes?
