Contus/lac/hem brainstem with LOC status unknown, sequela

This code signifies a traumatic injury to the brainstem, characterized by bruising, tearing, and bleeding, where the patient's level of consciousness at the time of injury is not documented. It is specifically used to report the long-term effects or complications arising from such an injury, rather than the initial acute event.

Apply this code when documenting the sequelae of a brainstem contusion, laceration, or hemorrhage with an unknown consciousness status. This is appropriate for follow-up encounters addressing chronic neurological deficits, cognitive impairments, or other lasting consequences directly attributable to the past brainstem trauma. Documentation should clearly link the current condition to the previous brainstem injury.

• Always use an external cause code (V00-Y99) in conjunction with this code to describe the circumstances of the injury.
• Do not use this code for the initial acute injury; instead, use the appropriate acute S06.38A_ code.
• Ensure documentation explicitly states "sequela" or describes a chronic condition resulting from the past brainstem trauma.
