Unsp injury of right innominate or subclavian artery, init

This code signifies an injury to the right innominate (brachiocephalic) or subclavian artery where the specific type of injury (e.g., laceration, contusion, dissection) has not yet been determined or documented. These are major arteries supplying blood to the right arm, head, and neck, and injury can result from trauma.

This code is appropriate for the initial encounter of a patient presenting with suspected or confirmed trauma to the right innominate or subclavian artery, and the precise nature of the arterial damage is still under investigation or not yet specified in the medical record. It is used when the documentation indicates an arterial injury but lacks further detail regarding its type.

• Only use this code for the initial encounter of the injury. Subsequent care would use a different seventh character.
• Avoid using this code if the specific type of arterial injury (e.g., laceration, puncture, rupture) is clearly documented.
• Always seek clarification from the provider if the documentation is vague regarding the specific artery or type of injury.
