Injury of r int carotid, intcr w LOC of 6-24 hrs, sequela

This code signifies a chronic or late effect of a traumatic injury to the intracranial segment of the right internal carotid artery, specifically when the initial injury resulted in a loss of consciousness lasting between 6 and 24 hours. This diagnosis indicates that residual symptoms or conditions are being addressed long after the acute phase of the original trauma.

Apply this code when documenting follow-up care for a patient experiencing sequelae from a past intracranial right internal carotid artery injury. The medical record must clearly state that the initial injury involved a loss of consciousness for 6 to 24 hours and that the current encounter addresses a chronic complication or residual effect.

• Requires a seventh character "S" to indicate sequela, meaning the patient is receiving care for the late effects of the injury.
• Do not use for acute injury encounters; this code is exclusively for chronic or residual conditions.
• Ensure documentation specifies the side (right) and the intracranial portion of the internal carotid artery.
