Small intestine carcinoma is among the rarest and most challenging cancers to diagnose—especially given its nonspecific symptoms and varied histologic presentations. In this month’s Oncology Coding Break, Monica Reece, ODS-C, RHIT, takes a deep dive into this uncommon disease, offering a comprehensive review of small intestine anatomy, histologic types, and the AJCC staging guidelines based on site and morphology.

Key Learning Highlights:

???? Anatomy Refresher: Understand the functional segmentation of the small intestine—duodenum, jejunum, and ileum—and how these sections relate to cancer diagnosis and staging.

???? Histologic Variability: Explore the wide range of histologies, from mucinous adenocarcinomas to neuroendocrine tumors and gastrointestinal stromal tumors (GISTs). The presentation also includes staging chapter guidance by histology and tumor location.

???? Staging & Coding Focus: Review staging details using the AJCC 9th edition and learn how histology impacts chapter selection. The break also covers how to assign Summary Stage 2018 and STORE-compliant surgery codes.

???? Real-World Application: A detailed case scenario highlights a mucinous adenocarcinoma of the terminal ileum with extension into the right ovary. The example walks through operative details, histologic findings, margin status, lymph node evaluation, and final staging (pT4, pN0, cM0 | Stage IIB).

Whether you’re refining your understanding of rare gastrointestinal tumors or seeking clarity on staging guidance, this session equips oncology data professionals with practical tools to abstract small intestine cancers accurately and confidently.
