Major laceration of left carotid artery, initial encounter

This code signifies a significant tear or cut in the left carotid artery, a major blood vessel supplying the brain. This injury is typically severe, often resulting in substantial hemorrhage and potential neurological compromise.

Apply this code for initial encounters involving a patient presenting with a confirmed major laceration of the left carotid artery, often due to penetrating trauma to the neck. Documentation should clearly specify the left side and the nature of the injury as a laceration, distinguishing it from a minor tear or contusion.

• Ensure documentation specifies "major laceration" versus other types of carotid artery injuries (e.g., puncture, contusion).
• Verify the laterality (left) is clearly documented.
• This code is for the initial encounter; subsequent encounters for the same injury will require a different seventh character.
