I work for a GI group and we have recently run into an issue with UHC and the pre-colonoscopy visit. These are being billed with the appropriate level E/M code and dx code V76.51-special screening malignant neoplasm colon. We are being told by UHC (this is the only payer processing these claims this way) that this code combination is not considered preventive. We have always billed this way and they are usually covered under pt's preventive portion of plan. Can we bill Preventive Medicine codes99381-99397? If we can what is the doctor required to do and document during these visits? Has anyone else run into this recently?
