ICD-10 Code D13.30 – Benign neoplasm of unspecified part of small intestine (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D13.30 – Benign neoplasm of unspecified part of small intestine
What it is
This code identifies a noncancerous tumor in the small intestine when the exact site is not documented. It tells you the lesion is benign, but the record does not specify duodenum, jejunum, or ileum.
Clinical signs
Clinical features vary; refer to documentation. Benign small-intestinal neoplasms may be found incidentally or during evaluation of abdominal pain, bleeding, obstruction, or anemia, but the specific presentation depends on the lesion and pathology.
When to use this code
Use D13.30 when the provider documents a benign neoplasm of the small intestine and does not name the involved segment. It is also appropriate when pathology or imaging confirms a benign lesion, but the report leaves the site unspecified. Code only when the documentation supports a neoplasm, not a nonspecific mass.
Do not use for
Do not use this code for malignant tumors, polyps without a neoplasm diagnosis, or inflammatory lesions. If the record identifies a specific small-intestine segment, check documentation for a more precise code.
Coding tip
If the site is unclear, query for the exact small-intestine location before defaulting to an unspecified code.
