T20.6 — Corrosion of second degree of head, face, and neck
Is T20.6 billable?
No — T20.6 is a non-billable header code. T20.6 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 33 billable codes beneath T20.6.
