Obst due to fb acc left in body fol surgical op, sequela

This code signifies a long-term complication arising from a foreign object inadvertently retained within a patient's body after a surgical procedure. The retained object is now causing an obstruction. This represents a delayed or chronic effect of the initial surgical error.

Apply this code when a patient presents with symptoms of an obstruction (e.g., bowel obstruction, urinary obstruction) that is definitively attributed to a foreign body (e.g., surgical sponge, instrument fragment) left inside during a prior surgery. This code is appropriate for reporting the sequela, or late effect, of such an event.

• Requires a seventh character "S" to indicate sequela, meaning the complication is a late effect.
• Always sequence this code after the code for the specific type of obstruction (e.g., K56.60 for unspecified intestinal obstruction).
• Ensure documentation clearly links the obstruction to a retained foreign body from a previous surgical encounter.
