In simple words: This code indicates a severe form of appendicitis where the appendix has ruptured, causing infection and a contained pocket of pus in the surrounding abdominal area.

This code signifies acute appendicitis characterized by perforation, localized peritonitis (inflammation of the peritoneum, the membrane lining the abdominal cavity), gangrene (tissue death due to loss of blood supply), and the presence of an abscess (a localized collection of pus).

Example 1: A 15-year-old patient presents with right lower quadrant pain, fever, and elevated white blood cell count. Imaging reveals a perforated appendix with localized peritonitis and an abscess. The patient undergoes appendectomy and drainage of the abscess., A 25-year-old patient experiences sudden onset of abdominal pain migrating to the right lower quadrant. Physical examination reveals tenderness and guarding. CT scan confirms acute appendicitis with perforation, localized peritonitis, and a peri-appendiceal abscess. The patient is treated with antibiotics and percutaneous drainage of the abscess, followed by interval appendectomy., A 35-year-old patient with a history of abdominal pain is admitted to the hospital with worsening symptoms. Diagnostic laparoscopy reveals a gangrenous and perforated appendix with localized peritonitis and an abscess. The patient undergoes laparoscopic appendectomy and drainage of the abscess.

Documentation should include details of the patient's presenting symptoms (e.g., abdominal pain, fever, nausea, vomiting), physical examination findings (e.g., tenderness, guarding, rebound tenderness), imaging results (e.g., ultrasound, CT scan) confirming the diagnosis, operative findings describing the perforated appendix, localized peritonitis, gangrene, and abscess, and details of the treatment provided (e.g., appendectomy, drainage of abscess).
