We had an outside company do a coding audit and we were dinged on the following. On the Operative report the doctor states that patient presents for a diagnostic colonoscopy. History of family cancer. We were billing these as a screening - G codes. They said that this should be billed 45378 with the v code. We have contacted the Doctors office that do these and they insist that this should be a screening. On the scedule sheet they state that it is a "recall" which to them is screening. We have told them that in order for us to bill any procedure as a screening in must state this some place on the chart or Op Recport. Am I correct? By the way I work in an ASC. We were also using the G codes for all of our payers and they have been paying, we also got dinged on that. Any feedback would be helpful.
