Cancer of the fundus, which is the upper curved portion of the stomach.
Coding Tips
- •The fundus is the uppermost part of the stomach body; ensure it is not confused with the cardia
- •Document should specify fundus location to differentiate from other stomach regions
Clinical Significance
Malignant neoplasm of the gastric fundus is a cancer in the upper dome-shaped portion of the stomach, which can be particularly challenging to detect early due to its location. Fundal cancers may grow to significant size before causing symptoms, often presenting at advanced stages. This anatomical specificity is important for surgical planning and affects prognosis, as fundal tumors may require different operative approaches than cancers in other gastric regions.
Documentation Requirements
- ✓Documentation confirming fundus as the primary tumor location (upper dome of stomach)
- ✓Histological type (adenocarcinoma, gastrointestinal stromal tumor, lymphoma, etc.)
- ✓Stage of disease with depth of invasion
- ✓Current treatment status
- ✓Distinction from cardia (C16.0) and body (C16.2) involvement
