Ac appendicitis with gen peritonitis, with perf, w/o abscs

This diagnosis code signifies an acute inflammation of the appendix that has progressed to a rupture, leading to widespread infection and inflammation within the abdominal cavity. It specifically indicates that while perforation has occurred, there is no localized collection of pus (abscess) present.

Apply this code when documentation clearly states acute appendicitis with evidence of perforation and generalized peritonitis, but explicitly denies the presence of an abscess. This scenario often involves patients presenting with severe, diffuse abdominal pain, fever, and signs of sepsis.

• Ensure documentation specifies "generalized" peritonitis, not localized, to differentiate from other peritonitis codes.
• Confirm the absence of an appendiceal abscess; if an abscess is present, a different code would be appropriate.
• Always review operative reports and pathology findings for definitive confirmation of perforation and the absence of an abscess.
