Inj r int crtd, intcr w LOC of 30 minutes or less, sequela

This code signifies a sequela (late effect) of a traumatic injury to the intracranial segment of the right internal carotid artery, which was associated with a brief loss of consciousness lasting 30 minutes or less at the time of the initial injury. It indicates that the patient is now presenting with a residual condition or complication directly attributable to that past injury.

Apply this code when a patient is being treated for a chronic or residual problem stemming from a previous traumatic injury to the right intracranial internal carotid artery, and the initial injury involved a loss of consciousness of 30 minutes or less. Documentation must clearly link the current condition as a sequela of the specified past trauma.

• Always sequence this sequela code after the code describing the specific residual condition or complication being treated.
• Ensure documentation explicitly states "sequela" or describes a chronic condition directly resulting from the past injury.
• Verify the laterality (right) and the specific vessel (internal carotid artery, intracranial portion) are clearly documented, along with the duration of initial loss of consciousness.
