When billing a high risk screening colonoscopy for personal history of colon polyps (Z86.010), do you bill Z09 or Z12.11 as primary dx? As I understand it, per the ICD 10 guidelines, we should be billing Z09 as primary and Z86.010 secondary on claim. However, I am being told via an audit that Z12.11 should be billed as primary to Z86.010. The auditor is siting Coding Clinic 2017. I'm confused why they would be using guidelines so old to determine how to bill, especially since I believe this was prior to Z09 and Z08 codes being added to ICD 10. Thoughts? Has anyone else run into this and how are you currently billing these colonoscopies?
