Perf due to fb acc left in body following endo exam, sequela

This code signifies a delayed complication where a foreign object, inadvertently retained after an endoscopic procedure, causes a perforation in an organ or tissue. This represents a long-term consequence or sequela of the initial event, not an acute or immediate perforation.

Apply this code when documentation clearly indicates a perforation occurring at a later date due to a foreign body that was unintentionally left inside the patient following an endoscopic examination. This is appropriate for follow-up encounters addressing the chronic or persistent effects of such an event.

• Always sequence this code after the primary diagnosis describing the specific perforation (e.g., perforation of colon, stomach).
• Ensure the documentation explicitly links the perforation to a retained foreign body from a previous endoscopic procedure.
• Do not use for acute perforations occurring during the endoscopic procedure itself.
