Unsp intcrn injury w LOC of 30 minutes or less, sequela

This code signifies a past, unresolved intracranial injury where the specific type of injury is not documented, and the patient experienced a brief loss of consciousness (30 minutes or less) at the time of the initial injury. It is used to report the long-term effects or complications arising from such an injury, rather than the acute event itself.

Apply this code when a patient presents for treatment of a sequela (e.g., post-concussive syndrome, cognitive deficits, chronic headaches) directly attributable to a previously sustained, unspecified intracranial injury with documented loss of consciousness of 30 minutes or less. Documentation must clearly link the current condition to the prior injury and specify that the initial injury was an "unspecified intracranial injury" with the stated duration of unconsciousness.

• This "S" code indicates a sequela, meaning it should be used for residual conditions after the acute phase of the injury has passed.
• Always sequence the code for the specific sequela (e.g., R51 for headache) first, followed by this code as a secondary diagnosis to indicate the cause.
• Ensure documentation explicitly states "unspecified intracranial injury" and the duration of loss of consciousness; avoid using this code if a more specific intracranial injury was diagnosed.
