C14 — Malignant neoplasm of other and ill-defined sites in the lip, oral cavity and pharynx
Is C14 billable?
No — C14 is a non-billable header code. C14 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 3 billable codes beneath C14.

Excludes1 — never code together
