Traumatic brain compression without herniation, sequela

This code signifies the long-term effects or complications arising from a past episode of traumatic brain compression that did not involve brain herniation. It describes persistent neurological or cognitive deficits directly attributable to the previous brain compression injury. This is not for the acute injury itself, but rather the lasting consequences.

Use this code when documenting a patient presenting with ongoing neurological or cognitive sequelae (e.g., persistent headaches, memory issues, motor deficits) directly linked to a previously sustained traumatic brain compression without herniation. Documentation should clearly state the prior injury and the current, related residual symptoms.

• Always sequence this code after the primary sequela code (e.g., G90.8 for other specified disorders of the autonomic nervous system if that's the sequela).
• Do not use this code for the acute phase of the traumatic brain compression; use an acute injury code from the S06 category instead.
• Ensure the medical record explicitly links the current symptoms to a past traumatic brain compression and confirms the absence of herniation at the time of the original injury.
