K35.31

Acute appendicitis with localized peritonitis and gangrene, without perforation

Clinical Classification Guidelines

Medical Intelligence & Overview

ICD-10 Code K35.31 refers to a specific form of acute appendicitis characterized by inflammation of the appendix that has resulted in tissue death (gangrene) and localized peritonitis, but without the appendix rupturing (perforation). This condition requires prompt medical attention to prevent further complications. Recognizing the signs and understanding the nature of this illness can help in seeking early medical care.

Causes & Symptoms

Clinical Causes: Blockage of the appendix opening due to hard stool, foreign bodies, or tumors. Infections caused by bacteria, viruses, or parasites that lead to inflammation. Genetic factors or immune responses that predispose an individual to appendicitis. Dietary factors, such as low fiber intake, which may contribute to stool hardening and blockage.

Key Symptoms: Sudden abdominal pain that typically begins around the navel and migrates to the lower right abdomen. Pain that worsens with movement, coughing, or sneezing. Nausea and vomiting. Loss of appetite. Low-grade fever and chills. Tenderness when pressing on the affected area. Possibly localized swelling or redness over the abdomen.

Diagnostic & Treatment

Diagnosis Path: Physical examination to assess tenderness, swelling, and signs of guarding. Blood tests to identify elevated white blood cell counts indicative of infection. Urinalysis to rule out urinary tract issues. Imaging studies such as abdominal ultrasound or computed tomography (CT) scan to visualize the inflamed appendix and assess for gangrene or localized peritonitis.

Treatment Protocols: Management typically involves surgical removal of the inflamed appendix, known as an appendectomy, often performed laparoscopically. Antibiotics are administered to combat infection and prevent spread of infection to other parts of the abdomen. Postoperative care includes monitoring for signs of complications such as infection or the development of widespread peritonitis.

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
