The following codes were created for acute appendicitis:
- K35.20 Acute appendicitis with generalized peritonitis, without abscess
- K35.21 Acute appendicitis with generalized peritonitis, with abscess
- K35.30 Acute appendicitis with localized peritonitis, without perforation or gangrene
- K35.31 Acute appendicitis with localized peritonitis and gangrene, without perforation
- K35.32 Acute appendicitis with perforation and localized peritonitis, without abscess
- K35.33 Acute appendicitis with perforation and localized peritonitis, with abscess
- K35.890 Other acute appendicitis without perforation or gangrene
- K35.891 Other acute appendicitis without perforation, with gangrene
Appendicitis occurs when blockage of the appendix causes increased pressure and inflammation. There may be pain around the navel or the right side of the lower abdomen, loss of appetite, and nausea. Acute appendicitis progresses to gangrene as circulation to the appendix is obstructed and the lumen become necrotic. Profuse vomiting may be a sign that there is rupture or perforation with peritonitis as the peritoneal space becomes contaminated with bacteria.
Localized peritonitis involves a confined area of the abdominal cavity, usually around an abscess or collection of pus. General, diffuse peritonitis affects most of the peritoneum. Perforation, the presence of an abscess, and peritonitis are key complications of appendicitis that physicians use to describe the severity of acute appendicitis and to determine the most appropriate course of treatment. Percutaneous drainage of the abscess with the administration of antibiotics is one effective treatment of acute appendicitis with peritonitis. However, an appendectomy is the standard treatment for acute appendicitis, and is the most common reason for surgery in children.
