Injury of r int carotid, intcr w LOC of 6-24 hrs, subs

This code signifies a traumatic injury to the intracranial segment of the right internal carotid artery, not specified elsewhere, that resulted in a prolonged loss of consciousness lasting between 6 and 24 hours. This particular code is used for encounters following the initial treatment of the injury.

Apply this code for follow-up care of a patient who previously sustained a traumatic intracranial right internal carotid artery injury with an initial loss of consciousness of 6 to 24 hours. Documentation should clearly indicate the injury location, the duration of the initial loss of consciousness, and that this is a subsequent encounter for the condition.

• Ensure the documentation specifies "right" internal carotid artery and "intracranial portion."
• Verify the duration of loss of consciousness was precisely 6 to 24 hours for accurate code selection.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
