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

This code describes inflammation of the peritoneum that is not caused by infection, but rather by a non-infectious foreign material that was unintentionally retained within the body following a surgical or other invasive procedure. This condition typically presents with abdominal pain, tenderness, and distension, and is considered an initial encounter for treatment.

Use this code when a patient develops aseptic peritonitis directly attributable to a foreign object (e.g., surgical sponge, instrument fragment) inadvertently left inside the body during a previous medical procedure. This applies to the initial phase of care for this specific complication.

• Ensure documentation clearly states the peritonitis is aseptic and directly linked to a retained foreign body from a procedure.
• Verify this is the patient's first encounter for the treatment of this specific complication.
• Do not use for peritonitis due to infection or other non-procedural causes.
