K03 — Other diseases of hard tissues of teeth

Not billable

Is K03 billable?

No — K03 is a non-billable header code. K03 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 11 billable codes beneath K03.
