C09 — Malignant neoplasm of tonsil
Not billable
Is C09 billable?
No — C09 is a non-billable header code. C09 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 4 billable codes beneath C09.
