Injury of left internal carotid artery, intracranial portion, not elsewhere classified with loss of consciousness greater than 24 hours without return to pre-existing conscious level with patient surviving, subsequent encounter

📋Clinical Description

This code signifies a traumatic injury to the intracranial segment of the left internal carotid artery, resulting in a prolonged loss of consciousness exceeding 24 hours, from which the patient has not recovered to their baseline cognitive state. This indicates severe neurological damage following the initial insult.

🎯When to Use

Apply this code for subsequent encounters when a patient is being treated for the sequelae of a left intracranial internal carotid artery injury that initially caused a coma lasting over 24 hours, and they remain in a state of altered consciousness. Documentation must clearly state the specific artery involved, the duration of unconsciousness, and the patient's current neurological status indicating no return to pre-injury consciousness.

💡Coding Tips

Ensure documentation specifies "left" internal carotid artery and "intracranial portion."
Verify the duration of loss of consciousness exceeded 24 hours and the patient's current conscious level remains below baseline.
This "D" seventh character indicates a subsequent encounter for care after the initial active treatment phase.
