S06.A — Traumatic brain compression and herniation

Not billable

Is S06.A billable?

No — S06.A is a non-billable header code. S06.A 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 6 billable codes beneath S06.A.
