ICD-10 Code D13.1 – Benign neoplasm of stomach (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D13.1 – Benign neoplasm of stomach
What it is
D13.1 identifies a noncancerous tumor arising in the stomach. It means the growth is benign, but it may still need evaluation because location and size can affect care.
Clinical signs
Clinical features vary; refer to documentation. Some patients are asymptomatic, while others may have upper gastrointestinal symptoms, bleeding, or an endoscopically noted gastric mass.
When to use this code
Use D13.1 when the provider documents a benign neoplasm of the stomach, including a confirmed gastric polyp or other benign gastric tumor. Code it when pathology, endoscopy, or operative findings support a benign stomach lesion. Do not assume benignity from imaging alone unless documented.
Do not use for
Do not use this code for malignant gastric tumors or unspecified stomach masses. Check documentation if the lesion is inflammatory, ulcer-related, or if the pathology report does not confirm a benign neoplasm.
Coding tip
Verify the exact site and pathology wording before assigning D13.1.
