Aseptic peritonitis due to forn sub acc left dur proc, sqla

This code signifies inflammation of the peritoneum that is not caused by bacterial infection, resulting from a foreign object inadvertently retained within the body during a surgical or medical procedure. This aseptic inflammation is a long-term consequence or late effect of the initial procedural complication.

Apply this code when documentation clearly indicates a patient is experiencing non-infectious peritonitis that is directly attributable to a foreign body (e.g., surgical sponge, instrument fragment) left inside during a previous intervention. This code is appropriate for chronic or delayed presentations of such a complication, after the initial acute phase.

• Ensure the documentation specifies "aseptic" peritonitis and explicitly links it to a retained foreign body from a prior procedure.
• The "S" seventh character indicates a sequela, meaning this code is for complications or conditions arising as a direct result of an earlier injury or disease.
• Always code the specific type of retained foreign body if known and documented, in addition to this code.
