T24.7 — Corrosion of third degree of lower limb, except ankle and foot
Not billable
Is T24.7 billable?
No — T24.7 is a non-billable header code. T24.7 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 45 billable codes beneath T24.7.
