Minor laceration of left innominate or subclavian vein, init

This code signifies a superficial tear or cut to the left innominate (brachiocephalic) or subclavian vein, which are major blood vessels in the upper chest and neck. This type of injury is typically not extensive and does not involve significant disruption of the vessel wall.

Apply this code for initial encounters involving patients presenting with a documented minor laceration of the left innominate or subclavian vein. This often occurs due to trauma, such as a stab wound, penetrating injury, or iatrogenic injury during a medical procedure.

• Ensure documentation specifies "minor laceration" and the "left" side for accurate coding.
• Verify this is the patient's initial encounter for this specific injury; subsequent encounters will require different seventh characters.
• Distinguish from more severe injuries like transection or rupture, which have separate codes.
