G92 — Toxic encephalopathy
Not billable
Is G92 billable?
No — G92 is a non-billable header code. G92 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 8 billable codes beneath G92.
