Major laceration of inferior vena cava, initial encounter

This code signifies a significant tear or cut in the inferior vena cava (IVC), the large vein that carries deoxygenated blood from the lower body to the heart. This type of injury is typically severe, often resulting in substantial hemorrhage and hemodynamic instability.

Apply this code for initial encounters involving traumatic injuries, such as penetrating wounds (e.g., stab wounds, gunshot wounds) or blunt force trauma, that directly result in a major laceration of the IVC. It is also appropriate for iatrogenic lacerations occurring during surgical procedures, when documented as a major laceration.

• Ensure documentation clearly specifies a "major laceration" of the IVC, as opposed to a minor tear or contusion.
• Verify that this is the initial encounter for the injury; subsequent encounters will require a different seventh character.
• Always code the external cause of the injury (e.g., W25.XXXA for contact with sharp glass) in conjunction with this diagnosis.
