What is the ICD-10-CM Diagnosis Code for Tuberculous enteritis?

The ICD-10-CM diagnosis code for Tuberculous enteritis is A18.32.

Enteritis is the inflammation of the small intestine, often caused by infections, irritants, or autoimmune conditions.

Tuberculous enteritis is a rare form of enteritis caused by Mycobacterium tuberculosis infecting the small intestine.

It usually spreads from the lungs or through ingestion of infected material. Common symptoms include abdominal pain, diarrhea, weight loss, fever, and sometimes intestinal obstruction.

The disease is more likely in people with low immunity or a history of tuberculosis. Diagnosis is made through imaging, endoscopy, and biopsy.

Treatment includes long-term use of anti-tuberculosis drugs. Early medical attention helps prevent serious complications.

Proper documentation using A18.32 ensures patients receive appropriate care and enables accurate healthcare reimbursement.

History Background of ICD-10-CM Diagnosis Code A18.32

The ICD-9-CM system, first introduced in 1979, provided the initial framework for coding diseases and health-related conditions in the United States.

The ICD-9-CM diagnosis code for Tuberculous enteritis is 014.80(Other tuberculosis of intestines, peritoneum, and mesenteric glands, unspecified) in 2015.This coding remained consistent from 1979 to 2015.

While the ICD-9-CM system offered a basic approach to disease classification, modern healthcare needs more detail and specificity.

To address this, the ICD-10-CM system was launched in 2015, introducing a more comprehensive and accurate coding structure.

The transition from ICD-9-CM to ICD-10-CM significantly improved the ability to document and analyze conditions such as Tuberculous enteritis.

The 2025 edition of ICD-10-CM A18.32 became effective on October 1, 2024.
