Unsp intracranial injury w LOC of 6-24 hrs, sequela

This code signifies a long-term consequence or late effect stemming from an unspecified head injury that initially caused a loss of consciousness lasting between 6 and 24 hours. The original injury itself is not specified beyond its intracranial nature, and the sequela refers to any residual condition or complication arising from that past event.

Use this code when documenting a patient presenting with a current condition that is a direct result of a previous, unspecified intracranial injury where the initial loss of consciousness was explicitly documented as 6 to 24 hours. This code is appropriate for follow-up encounters addressing chronic issues related to the past trauma, such as post-concussive syndrome, cognitive deficits, or persistent neurological symptoms.

• Always sequence this sequela code after the code describing the specific current condition or symptom being treated.
• Ensure documentation clearly links the current condition to the past intracranial injury and specifies the duration of the initial loss of consciousness.
• Distinguish from acute injury codes (which would not have the "S" seventh character) and codes for specified types of intracranial injuries.
