Injury of r int carotid, intcr w LOC of 1-5 hrs 59 min, subs

This code signifies an intracranial injury to the right internal carotid artery, not specified elsewhere, that resulted in a loss of consciousness lasting between one and just under six hours. This diagnosis indicates a subsequent encounter for this specific injury.

This code is appropriate for follow-up care of a patient previously diagnosed with an intracranial right internal carotid artery injury. Documentation must clearly state the injury location, the duration of the initial loss of consciousness (1-5 hours 59 minutes), and that the current visit is for subsequent treatment or monitoring.

• Ensure documentation specifies "right" internal carotid artery and "intracranial" portion.
• Verify the duration of loss of consciousness falls precisely within the 1 hour to 5 hours 59 minutes range.
• Confirm this is a subsequent encounter; an initial encounter would require a different 7th character.
