Intcran inj w LOC of 6 hours to 24 hours, sequela

This code signifies a long-term consequence (sequela) resulting from a traumatic brain injury (TBI) that involved an intracranial injury other than those specifically classified as diffuse, focal, or epidural/subdural/subarachnoid hemorrhage. The initial injury was characterized by a prolonged period of unconsciousness, lasting between 6 and 24 hours. The sequela could manifest as cognitive deficits, neurological impairments, or other lasting effects directly attributable to the original trauma.

Use this code when documenting the residual effects or late complications of a past intracranial injury where the patient experienced a loss of consciousness for 6 to 24 hours. Documentation should clearly state the connection between the current condition and the prior TBI, specifying the nature of the intracranial injury and the duration of the initial loss of consciousness. This code is appropriate for follow-up visits addressing chronic issues stemming from the original trauma.

• Always sequence this sequela code after the primary diagnosis for the current manifestation of the sequela (e.g., cognitive deficit, epilepsy).
• Ensure the medical record explicitly links the current condition to a past TBI with a documented loss of consciousness of 6-24 hours.
• Distinguish from acute injury codes (without the "S" seventh character) which are used for the initial encounter of the injury.
