Code Description

ICD-10 A18.32 is a billable code used to indicate a diagnosis of tuberculous enteritis.

Key Diagnostic Point:

Tuberculous enteritis is a form of extrapulmonary tuberculosis that primarily affects the intestines, particularly the ileum. It is caused by Mycobacterium tuberculosis, the bacterium responsible for tuberculosis (TB). The condition can manifest with a variety of gastrointestinal symptoms, including abdominal pain, diarrhea, weight loss, and malabsorption. Diagnosis typically involves a combination of clinical evaluation, imaging studies such as CT scans or ultrasounds, and microbiological tests, including stool cultures and biopsies. Sputum tests and chest X-rays may also be performed to rule out pulmonary involvement. Treatment usually consists of a multi-drug regimen, including isoniazid, rifampicin, ethambutol, and pyrazinamide, administered over a period of at least six months. Monitoring for drug resistance is crucial, as resistance can complicate treatment and lead to poorer outcomes. Public health implications are significant, as TB is a contagious disease, necessitating contact tracing and isolation procedures for infected individuals to prevent transmission. The management of tuberculous enteritis requires a multidisciplinary approach, involving gastroenterologists, infectious disease specialists, and public health officials.
