Injury of l int carotid, intcr w/o LOC, init

This code signifies a traumatic injury to the intracranial segment of the left internal carotid artery, not specified as a dissection or other specific type, and occurring without any period of unconsciousness. It indicates an acute, initial presentation of such an injury.

This code is appropriate for patients presenting with an acute, non-dissecting injury to the left intracranial internal carotid artery due to trauma, where the patient remained conscious. Documentation should clearly state the laterality, intracranial location, and absence of loss of consciousness, as well as the traumatic etiology.

• Ensure documentation specifies "intracranial portion" and "left" internal carotid artery.
• Verify the absence of loss of consciousness; if present, a different code from the S06.82 series would be more appropriate.
• This "A" suffix indicates an initial encounter for active treatment; subsequent care would require a "D" or "S" suffix.
