We have a post transplant patient who had a colonoscopy in 2016. We used Z12.11 and Medicare paid. Patient did not have any other dx findings on report. Our transplant patients need to have routine colonoscopies every 5 years. Medicare denied her recent claim with Z12.11 and G0121. What ICD 10 code and CPT code should I use to get Medicare to pay?
