Traumatic brain compression without herniation, subs

This code signifies a traumatic brain injury where there is compression of the brain tissue due to an external force or internal swelling, but without evidence of brain herniation. It indicates that the patient is receiving follow-up care for this condition after the initial treatment phase.

Use this code for subsequent encounters when a patient is being treated for the ongoing effects or complications of a traumatic brain compression without herniation. Documentation should clearly indicate that the brain compression is a result of trauma and that there is no evidence of herniation. This code is appropriate for rehabilitation, medication management, or monitoring of the condition.

• Ensure documentation specifies "without herniation" to differentiate from codes involving herniation.
• Confirm this is a subsequent encounter; initial encounters would use the 'A' seventh character.
• Always sequence this code after the primary traumatic brain injury code, if applicable, or as the primary diagnosis if the brain compression is the focus of the encounter.
