Intcran inj w LOC of 30 minutes or less, sequela

This code signifies a long-term complication or late effect stemming from a specific type of intracranial injury. The initial injury involved the brain, was not otherwise classified, and resulted in a brief loss of consciousness lasting 30 minutes or less. The "sequela" indicates that the patient is now experiencing residual symptoms or conditions directly attributable to that past injury.

Apply this code when a patient presents with a current condition (e.g., post-concussion syndrome, cognitive deficits, chronic headaches) that is documented as a direct consequence of a previously sustained, specified intracranial injury with a brief loss of consciousness. Documentation must clearly link the current symptoms to the past injury and specify the initial injury type.

• Ensure the documentation explicitly states the current condition is a "sequela" or "late effect" of the specified intracranial injury.
• This code requires an additional code to identify the specific sequela (e.g., R51 for headache, F07.81 for postconcussional syndrome).
• Do not use this code for acute injuries; it is strictly for residual conditions occurring after the acute phase has passed.
