C17 — Malignant neoplasm of small intestine
Is C17 billable?
No — C17 is a non-billable header code. C17 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 6 billable codes beneath C17.
