A18.83

What This Code Means

This code describes tuberculosis infection that affects organs of the digestive system (such as the stomach, intestines, or other digestive organs) and doesn't fit into other more specific tuberculosis categories. It represents an active TB infection in the digestive tract rather than the more common lung tuberculosis.

Coding Tips

• •Verify the specific digestive organ affected in the clinical documentation; if a more specific site is documented (like TB of intestines or peritonitis), consider using a more specific code if available
• •Ensure the TB is confirmed as active tuberculosis and not latent TB; this code is for active disease only
