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

This code signifies a long-term complication arising from an obstruction caused by a foreign object that was unintentionally retained in a patient's body after an endoscopic procedure. This is a delayed effect or condition directly resulting from the initial accidental retention.

Use this code when documenting a patient presenting with symptoms of obstruction (e.g., pain, difficulty swallowing, bowel obstruction) that is definitively linked to a foreign body left behind during a prior endoscopic examination. This code is appropriate for follow-up encounters addressing the persistent effects of such an event, not the initial discovery or removal.

• Requires a seventh character 'S' to indicate sequela, meaning it's a late effect of the initial injury.
• Ensure documentation clearly links the current obstruction to a foreign body from a previous endoscopic procedure.
• Do not use for acute or initial presentations of a retained foreign body; this code is specifically for the long-term consequences.
