Inj right innominate or subclavian artery, subs encntr

This code signifies a documented injury to the right innominate (brachiocephalic) or subclavian artery that is not further specified as a laceration, puncture, or contusion, and is being treated during a subsequent encounter. This could include injuries like a dissection, pseudoaneurysm, or other non-traumatic arterial compromise resulting from an initial event.

Apply this code when a patient presents for follow-up care, such as wound checks, medication adjustments, or imaging studies, related to a previously diagnosed and treated "other specified" injury of the right innominate or subclavian artery. This is appropriate for ongoing management after the initial acute treatment phase.

• Ensure documentation clearly states "other specified injury" and specifies the right innominate or subclavian artery.
• Verify that the encounter is indeed "subsequent" and not the initial treatment for the injury.
• Always review the medical record for any additional specific injury details that might allow for a more precise code (e.g., laceration, puncture).
