Injury of l int carotid, intcr w LOC of 31-59 min, sequela

This code signifies a past injury to the intracranial segment of the left internal carotid artery that was not otherwise specified, which resulted in a loss of consciousness lasting between 31 and 59 minutes. The "sequela" indicates that this code is used to report a late effect or complication of the initial injury, not the acute event itself.

Use this code when documenting a patient presenting with a current condition or symptom that is a direct result of a previously sustained injury to the left intracranial internal carotid artery, where the original injury involved a loss of consciousness of 31-59 minutes. Documentation should clearly link the current presentation to the past carotid injury and specify the duration of the initial loss of consciousness.

• Always sequence this sequela code after the code(s) for the current condition or symptom being treated.
• Ensure the medical record explicitly states the laterality (left) and the intracranial portion of the carotid artery was affected.
• Verify the exact duration of the loss of consciousness from the original injury documentation to differentiate from other S06.82- codes.
