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

This code describes a long-term complication arising from an object inadvertently retained within a patient's body after an unspecified surgical or medical procedure. The retained foreign body subsequently causes an obstruction, leading to ongoing symptoms or conditions. This code is used when the patient is experiencing the lasting effects or sequelae of this event.

Use this code when a patient presents with symptoms of an obstruction that is definitively linked to a foreign object accidentally left inside their body during a prior, unspecified procedure. This applies to follow-up encounters where the sequelae of the retained foreign body are being managed, rather than the initial discovery or acute event.

• Requires a seventh character "S" for sequela, indicating a late effect.
• Ensure documentation clearly links the obstruction to a retained foreign body from a past procedure.
• Do not use for acute or initial encounters where the foreign body is first discovered or removed.
