Major laceration of right innominate or subclav art, sequela

This code signifies a long-term complication or residual effect stemming from a severe tear in the right innominate (brachiocephalic) or subclavian artery. These arteries are critical for blood supply to the right arm, head, and neck. Sequelae can include chronic pain, pseudoaneurysm, stenosis, or other persistent issues resulting from the original injury.

Apply this code when documenting a patient presenting with a current condition directly attributable to a major laceration of the right innominate or subclavian artery that occurred in the past. This is appropriate for follow-up encounters addressing the chronic consequences of such an injury, rather than the initial acute trauma.

• Always sequence this sequela code after the code for the specific current condition being treated (e.g., chronic pain, pseudoaneurysm).
• Ensure documentation clearly links the current condition to the previous major arterial laceration.
• Do not use this code for acute injuries; use the appropriate acute trauma code for the initial encounter.
