Traumatic brain compression with herniation, subs

This code signifies a brain injury where increased intracranial pressure has led to the displacement of brain tissue through an opening in the dura or skull, occurring during a subsequent phase of care. This indicates the patient is receiving active treatment for the sequelae of the initial brain compression with herniation, or for complications arising from it.

Apply this code for follow-up encounters when a patient is being treated for the ongoing effects or complications of a previously diagnosed traumatic brain compression with herniation. Documentation should clearly indicate active treatment for the injury itself, rather than just routine follow-up after full recovery. Examples include managing post-surgical complications, ongoing neurological deficits, or continued monitoring for intracranial pressure.

• Ensure documentation specifies "subsequent encounter" and active treatment for the injury.
• Distinguish from initial encounter codes (S06.A1XA) or sequela codes (S06.A1XS) which are used for late effects.
• Always code the underlying cause of the traumatic brain injury if known and applicable, following sequencing guidelines.
