My doctor performed and EGD with biopsy. His report states "segmental continuous granularity, friability and erythema of the mucosa with no bleeding was noted in the antrum. These findings are compatible with gastritis. Cold forceps biopsies were performed". The pathology report comes back with a diagnosis of "Unremarkable antral-type mucosa". Because the doctor states finding were compatible with gastritis, could I use the unspecified gastritis code (535.50) or do I code the indication for the procedure, which was epigastric pain (789.06)? Thanks for you help!!
