2025 ICD-10-CM code A18.31
Tuberculous peritonitis. Tuberculous ascites.
Medical necessity for treatment is established by the confirmation of tuberculous peritonitis through appropriate diagnostic testing and the presence of clinical symptoms.
Diagnosis involves a review of medical history, physical examination, laboratory analysis of peritoneal fluid and biopsies, imaging studies (ultrasound, CT scan, chest X-ray). Treatment typically includes antituberculous medications.
In simple words: Tuberculous peritonitis is an infection of the lining of the abdominal cavity caused by tuberculosis bacteria. It can cause fluid buildup in the abdomen, pain, and other symptoms.
Inflammation of the peritoneum caused by Mycobacterium tuberculosis.This condition often presents with abdominal swelling, tenderness, and pain due to the accumulation of fluid (ascites). Other symptoms may include weight loss, fever, cough, and fatigue. It can sometimes lead to bowel obstruction or perforation.
Example 1: A patient with a history of pulmonary tuberculosis presents with abdominal pain, distension, and fever. Diagnostic tests confirm tuberculous peritonitis., A patient undergoing peritoneal dialysis develops abdominal pain and cloudy dialysate fluid. Cultures reveal Mycobacterium tuberculosis., An immunocompromised patient presents with ascites and constitutional symptoms.A laparoscopy with biopsy confirms tuberculous peritonitis.
Documentation should include evidence of infection with Mycobacterium tuberculosis affecting the peritoneum.This may include imaging findings (e.g., ascites, peritoneal thickening), laboratory results (e.g., positive cultures, AFB smear), and clinical findings (e.g., abdominal pain, fever).A history of tuberculosis exposure or prior infection should also be documented.
