Minor laceration of unsp innominate or subclav art, init

This code signifies a superficial tear or cut in either the innominate (brachiocephalic) artery or one of the subclavian arteries, where the specific artery involved is not documented. It indicates that the injury is minor and represents the initial treatment or evaluation for this specific trauma.

Use this code for patients presenting with a documented minor laceration to an unspecified major artery in the upper chest/shoulder region, such as from penetrating trauma (e.g., stab wound, gunshot wound). This code is appropriate when the medical record clearly indicates a laceration but lacks the specificity to identify whether it's the innominate or subclavian artery.

• Ensure documentation specifies "minor laceration" and "unspecified" for the artery.
• Confirm this is the patient's initial encounter for this injury; subsequent encounters will require a different seventh character.
• Always code the external cause of the injury in addition to this diagnosis code.
