ICD-10 Code C16.2 – Malignant neoplasm of body of stomach (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C16.2 – Malignant neoplasm of body of stomach
What it is
C16.2 identifies a malignant tumor arising in the body, or middle portion, of the stomach. Use it when documentation specifies this gastric site and confirms cancer.
Clinical signs
Clinical features may include upper abdominal pain, weight loss, early satiety, nausea, or anemia. Findings vary; refer to documentation and pathology when available.
When to use this code
Use C16.2 when the provider documents primary gastric cancer in the body of the stomach. It also fits pathology or imaging reports that clearly localize the malignancy to this stomach segment. If the record only says “stomach cancer” without a site, check documentation.
Do not use for
Do not use this code for benign gastric lesions, metastatic disease to the stomach, or malignancy in another stomach site. If the anatomic location is unclear, check documentation.
Coding tip
Code the exact stomach subsite only when the record names it; otherwise, query for clarification before assigning C16.2.
