Unsp intracranial injury w LOC of 1-5 hrs 59 min, sequela

This code describes the long-term effects or complications arising from an unspecified head injury that initially resulted in a loss of consciousness lasting between one hour and five hours and fifty-nine minutes. It indicates that the acute phase of the injury has passed, and the patient is now experiencing residual symptoms or conditions directly attributable to that original trauma.

This code is appropriate for documenting a patient's current condition when it is a sequela of a past intracranial injury with a documented loss of consciousness within the specified duration. It should be used for follow-up visits or when treating chronic issues stemming from the original trauma, after the initial injury has healed. Documentation must clearly link the current symptoms to the previous head injury and specify the duration of the initial loss of consciousness.

• Always sequence this sequela code after the code for the specific residual condition (e.g., post-traumatic epilepsy, cognitive deficits).
• Ensure the medical record explicitly states the duration of the loss of consciousness from the initial injury to support the 3rd character '3'.
• Do not use this code for acute injuries; it is strictly for sequelae. For acute injuries, use the appropriate S06.9X-A, D, or S codes.
