Major laceration of unsp innominate or subclav art, sequela

This code signifies a significant tear or wound in an unspecified innominate (brachiocephalic) or subclavian artery, representing a long-term complication or residual effect of a previous injury. This could include issues like chronic pseudoaneurysm, persistent fistula, or other lasting vascular damage resulting from the initial laceration.

Use this code when documenting the sequela of a major laceration to an innominate or subclavian artery, where the specific artery (right or left) is not documented. This applies to encounters where the patient is being treated for a chronic condition directly resulting from the original arterial injury, long after the acute phase has passed.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., I72.8 for pseudoaneurysm).
• Ensure documentation clearly states the condition is a sequela of a previous major laceration and specifies the affected artery type (innominate or subclavian).
• Avoid using this code for acute injuries; instead, use the appropriate acute injury code from the S25.12- category.
