Inj r int carotid, intcr w LOC of 30 minutes or less, init

This code signifies a traumatic injury to the intracranial segment of the right internal carotid artery, not classified elsewhere, resulting in a brief loss of consciousness lasting 30 minutes or less. This injury can lead to significant neurological deficits due to compromised blood flow to the brain.

Use this code for patients presenting with a documented traumatic injury to the right intracranial internal carotid artery, confirmed by imaging (e.g., CT angiography, MRA), and a history of transient loss of consciousness (30 minutes or less) immediately following the injury. This code is appropriate for the initial treatment of the injury.

• Ensure documentation specifies the right internal carotid artery and its intracranial portion.
• Verify the duration of loss of consciousness is explicitly stated as 30 minutes or less.
• Confirm this is the patient's initial encounter for this specific injury; subsequent encounters will require a different seventh character.
