Acute appendicitis with gen peritonitis, with perf and abscs

This code signifies an acute inflammation of the appendix that has progressed to a severe stage, characterized by a rupture of the appendix (perforation), widespread infection within the abdominal cavity (generalized peritonitis), and the formation of a localized collection of pus (abscess). This represents a life-threatening intra-abdominal infection requiring urgent surgical intervention.

Use this code when documentation clearly indicates acute appendicitis with evidence of both perforation and a generalized peritonitis, along with the presence of an abscess. This typically occurs in cases of delayed diagnosis or severe progression of appendicitis. Supporting documentation would include operative reports detailing these findings, as well as imaging reports (e.g., CT scan) confirming the abscess and peritonitis.

• Ensure documentation explicitly states "generalized" peritonitis, not just localized.
• Verify the presence of both perforation and abscess; all three elements must be present.
• This code is highly specific and should only be used when all components are clearly documented.
