Ac appendicitis w gen peritonitis, w abscs, unsp as to perf

This code signifies an acute inflammation of the appendix that has progressed to involve the entire abdominal cavity with peritonitis and has formed an abscess. The documentation does not specify whether the appendix itself has perforated.

Apply this code when the patient presents with symptoms and signs of acute appendicitis, and imaging or surgical findings confirm generalized peritonitis and an intra-abdominal abscess. Documentation must clearly state "generalized peritonitis" and "abscess" without specifying perforation of the appendix.

• Ensure documentation explicitly states "generalized peritonitis" and "abscess" in the context of acute appendicitis.
• Do not use this code if the documentation specifies localized peritonitis or if perforation is clearly documented as present or absent.
• Review operative reports and pathology findings carefully for details regarding perforation status and the extent of peritonitis and abscess formation.
