We are having a bit of a conundrum with these codes sort of overlapping themselves in verbage. I want to do this clarify and code this out correctly. The biopsies were obtained in the gastric antrum, but the scope went on down to view up to the 4th portion of the duodenum. We originally billed 43239 which states Esophagus, stomach and duodenum with biopsy, but the provider wants us to bill 44361 (he obtained brushings in that duodenum). What is appropriate in this situation? Bill both? Bill only 44361 or 43239?
