G93 — Other disorders of brain
Not billable
Is G93 billable?
No — G93 is a non-billable header code. G93 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 20 billable codes beneath G93.

How long has G93 existed?
G93 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
