2025 ICD-10-CM code A18.3

Tuberculosis of intestines, peritoneum, and mesenteric glands.

Use additional code to identify resistance to antimicrobial drugs (Z16.-). Refer to iFrameAI for detailed coding scenarios.

Medical necessity for treatment and related procedures is established by the confirmed diagnosis of tuberculosis involving the specified sites.The documentation should support the need for interventions such as antituberculous medications, surgical procedures (if applicable), and other supportive care.

Diagnosis involves evaluating patient history, laboratory analysis of sputum, gastric washings, peritoneal fluid, and biopsies. Procedures like endoscopy, ultrasound, CT scans, fine-needle aspiration, and exploratory laparotomy may be necessary. Treatment typically includes antituberculous chemotherapy with medications like isoniazid, rifampin, rifabutin, pyrazinamide, and ethambutol.Surgical intervention might be required for complications such as bowel perforation, stricture, or obstruction.

In simple words: This code represents tuberculosis that affects the intestines, the lining of the abdominal cavity, and the lymph nodes in the abdomen.It can cause abdominal pain, swelling, and other digestive issues. It often occurs in people who also have tuberculosis in their lungs.

This condition encompasses tuberculosis affecting the intestines, peritoneum (the membrane lining the abdominal cavity), and mesenteric glands (lymph nodes associated with the intestines). It often presents with abdominal swelling, tenderness, pain, rectal bleeding, constipation, ascites (fluid accumulation in the abdomen), weight loss, and potentially bowel obstruction or perforation.Symptoms of pulmonary tuberculosis, such as fever, cough, and malaise, may also be present.

Example 1: A patient with a history of pulmonary tuberculosis presents with abdominal pain, ascites, and weight loss. Diagnostic tests confirm tuberculosis of the intestines, peritoneum, and mesenteric glands., A patient undergoing treatment for pulmonary tuberculosis develops bowel obstruction. Further investigation reveals tuberculous involvement of the intestines and mesenteric lymph nodes., An immunocompromised patient experiences abdominal swelling and tenderness. Biopsy and laboratory analysis confirm tuberculosis affecting the peritoneum and mesenteric glands, with no evidence of pulmonary involvement.

Documentation should include evidence of tuberculosis affecting the intestines, peritoneum, and/or mesenteric glands. This may include imaging studies (ultrasound, CT scan), laboratory results (AFB smear and culture), endoscopic findings, and/or histopathology from biopsies.Patient history, physical exam findings, and details of treatment should also be documented.
