Obst due to fb acc left in body fol oth procedure, sequela

This code describes a long-term complication arising from a foreign object inadvertently retained within the body after a surgical or other invasive medical procedure. The obstruction is a direct result of this retained foreign body, manifesting as a sequela, meaning it's a late effect or consequence of the initial event.

Use this code when a patient presents with symptoms of obstruction (e.g., bowel obstruction, urinary obstruction, vascular obstruction) that are definitively linked to a foreign object left inside the body during a prior medical intervention. This applies to situations where the retained object was discovered and is now causing a persistent or chronic obstructive issue.

• Always sequence this code after the code for the specific type of obstruction (e.g., K56.60 for unspecified intestinal obstruction).
• Ensure documentation clearly states the foreign body was "accidentally left in" and is causing an "obstruction" as a "sequela."
• Do not use for complications occurring during the initial encounter; this code is for late effects.
