Inj r int crtd, intcrn portion, NEC LOC status unknown, subs

This code signifies a traumatic injury to the intracranial segment of the right internal carotid artery, where the patient's consciousness status following the injury is not documented. This specific code is used for follow-up care after the initial treatment of the injury.

Apply this code for subsequent encounters when a patient is receiving ongoing treatment or follow-up for a previously diagnosed intracranial right internal carotid artery injury with an unknown loss of consciousness status. Documentation should clearly indicate the injury's location, the "subsequent encounter" status, and the lack of information regarding consciousness at the time of injury.

• Requires documentation of "subsequent encounter" for ongoing care, not initial treatment.
• Ensure the laterality (right) and intracranial portion of the internal carotid artery are explicitly stated.
• Distinguish from codes for initial encounters or those with known consciousness status.
