Injury to innominate and subclavian veins

This code signifies a traumatic injury affecting the major veins in the upper chest and shoulder region, specifically the innominate (brachiocephalic) and subclavian veins. These injuries can result from blunt or penetrating trauma and may lead to significant hemorrhage or vascular compromise.

Apply this code when documentation clearly indicates a laceration, contusion, rupture, or other traumatic damage to the innominate or subclavian veins. This typically occurs in scenarios involving severe chest trauma, such as motor vehicle accidents, stabbings, or gunshot wounds to the neck/upper thorax.

• Specify the type of injury (e.g., laceration, contusion) if documented, as this code is a general category.
• Always sequence this code after the primary external cause of injury (E-code).
• Consider additional codes for associated injuries to nerves, arteries, or surrounding tissues.
