0.000What This Code Means
Cancer of the body of the stomach, which is the central main portion of the stomach.
Coding Tips
- •The body is the largest section of the stomach between the fundus and antrum
- •Verify documentation specifies body location and does not describe fundus or antral involvement
Clinical Significance
Cancer of the gastric body represents malignancy in the largest portion of the stomach, where most gastric acid secretion occurs. This location is clinically important because body tumors may cause diffuse infiltration (linitis plastica) and can significantly impact nutritional status and gastric function. Accurate site-specific coding supports appropriate risk adjustment for the complex multimodal treatments these patients typically require.
Documentation Requirements
- ✓Confirmation of body of stomach as the primary tumor location
- ✓Histological type and grade
- ✓Stage of disease including extent of gastric wall invasion
- ✓Documentation of any associated conditions (Helicobacter pylori, atrophic gastritis)
- ✓Treatment plan and current status
Commonly Confused Codes
C16.1 — Fundus: located above the body; confirm documentation distinguishes these adjacent regionsC16.3 — Pyloric antrum: located below the body toward the outlet; verify anatomical specificityC16.8 — Overlapping sites: use when tumor spans body plus other gastric regionsC16.9 — Stomach, unspecified: use body code when documentation specifies this location
