Injury of r int carotid, intcr w/o LOC, subs

This code describes a traumatic injury to the intracranial segment of the right internal carotid artery, specifically when the injury did not result in a loss of consciousness. This diagnosis indicates a follow-up encounter for the management or healing of such an injury.

Apply this code for subsequent encounters when a patient is receiving ongoing care for a previously diagnosed injury to the right intracranial internal carotid artery, and the initial injury did not involve loss of consciousness. Documentation should clearly state "subsequent encounter" or indicate follow-up care, such as wound checks, medication management, or imaging to monitor healing.

• Ensure the documentation specifies the right internal carotid artery and its intracranial portion.
• Verify that the patient did not lose consciousness at the time of the initial injury.
• Confirm this is a subsequent encounter; for initial encounters, a different 7th character (A) would be used.
