Applying proper coding is important for doctors practicing gastroenterology. The coding systems established by various organizations define tumors differently. As a result of changing concepts of tumor classification, there are coding and reimbursement issues following the confirmation of malignant lesions by nationwide cancer screening in patients with intramucosal carcinoma and neuroendocrine tumors of the colorectum. In addition, there have been discrepancies between the views of endoscopists and pathologists regarding tumor coding. The Korean Society of Gastrointestinal Endoscopy held an expert meeting and established a consensus for the coding of intramucosal carcinoma and neuroendocrine tumor of the colorectum.
