In simple words: This code represents an inflamed appendix that has spread to the nearby lining of the abdomen, but hasn't ruptured or developed dead tissue.

Acute appendicitis with localized peritonitis, without perforation or gangrene. This condition involves inflammation of the appendix, affecting the localized peritoneum, but without rupture or necrosis of the appendiceal wall.

Example 1: A 25-year-old male presents to the emergency department with right lower quadrant abdominal pain, nausea, and fever.A CT scan reveals an inflamed appendix with localized peritonitis but no perforation or gangrene.He undergoes a laparoscopic appendectomy., A 40-year-old female experiences increasing abdominal pain, tenderness to palpation in the right iliac fossa, and a low-grade fever.Diagnostic imaging confirms acute appendicitis with localized peritonitis, and she is treated with intravenous antibiotics, with surgical intervention deferred due to the localized nature of the inflammation., A teenager presents with abdominal discomfort, initially diagnosed as gastroenteritis. The pain worsens, localizing to the right lower quadrant, with associated fever.Imaging suggests acute appendicitis with localized peritonitis, prompting surgical consultation for appendectomy.

Documentation should include details of the presenting symptoms, physical examination findings (e.g., tenderness in the right lower quadrant, rebound tenderness, Rovsing's sign), laboratory results (e.g., elevated white blood cell count), imaging findings (e.g., CT scan showing appendiceal inflammation and peritonitis), and the chosen treatment approach (surgical or non-surgical).
