Intcran inj with LOC status unknown, sequela

This code signifies a long-term consequence or late effect stemming from a specific type of intracranial injury, where the initial injury involved a loss of consciousness of unknown duration. It is used when the acute phase of the injury has passed, and the patient is now experiencing residual symptoms or conditions directly attributable to that past trauma.

Apply this code when documentation clearly indicates a sequela (e.g., chronic headaches, cognitive deficits, post-traumatic epilepsy) resulting from a previously sustained "other specified intracranial injury" that included an unquantified period of unconsciousness. The medical record must explicitly link the current condition to the past head injury.

• Always sequence this sequela code after the code for the specific residual condition it describes.
• Ensure documentation specifies "sequela" or "late effect" and clearly links the current symptom to the past intracranial injury with unknown loss of consciousness.
• Do not use for acute injuries; this code is exclusively for chronic or residual effects.
