Benign carcinoid tumor of the stomach

This code signifies a non-cancerous, slow-growing neuroendocrine tumor originating in the stomach. These tumors arise from enterochromaffin-like cells and typically do not metastasize, though they can produce hormones.

Apply this code when documentation clearly states a benign carcinoid tumor located specifically within the stomach. This diagnosis is often made following endoscopic biopsy and subsequent histopathological examination confirming the benign nature.

• Ensure the documentation specifies "benign" to differentiate from malignant carcinoid tumors.
• Verify the tumor's primary site is explicitly stated as the stomach; do not use for carcinoids of other gastrointestinal sites.
• Do not confuse with other types of gastric polyps or adenomas; carcinoid tumors have distinct histological features.
