Perf due to fb acc left in body following punctr/cath, subs

This code signifies a new hole or tear in an organ or tissue that occurred because a foreign object, such as a medical device or material, was unintentionally left inside the body after a procedure like aspiration, a puncture, or catheterization. This specific code is for use during a follow-up visit after the initial treatment of the perforation.

Use this code when a patient presents for ongoing management or evaluation of a perforation that was caused by a retained foreign body from a previous invasive procedure. This applies to situations where the initial complication has already been addressed, and the patient is returning for subsequent care related to the perforation.

• Always assign an external cause code (V00-Y99) to identify the circumstances of the foreign body being left in.
• Ensure documentation clearly states the perforation is a direct result of the retained foreign body from the specified procedure type.
• Distinguish from initial encounter codes (T81.536A) and sequela codes (T81.536S).
