Tuberculous enteritis

This code identifies inflammation of the intestines specifically caused by Mycobacterium tuberculosis. It signifies an active infection affecting the gastrointestinal tract, often presenting with symptoms like abdominal pain, diarrhea, malabsorption, and weight loss. The infection can involve any part of the small or large intestine.

Apply this code when documentation confirms a diagnosis of tuberculous enteritis, typically supported by endoscopic findings, biopsy results showing granulomas or acid-fast bacilli, or positive cultures for M. tuberculosis from intestinal tissue. This diagnosis is often made in patients with a history of tuberculosis or those from endemic areas presenting with chronic gastrointestinal symptoms.

• Always confirm the infectious agent is Mycobacterium tuberculosis; other forms of enteritis require different codes.
• Code any associated manifestations of tuberculosis, such as pulmonary tuberculosis (A15-A16), if present and documented.
• Ensure documentation clearly distinguishes between active infection and a history of treated tuberculous enteritis.
