Tuberculosis of spleen

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

This is a serious infection caused by tuberculosis bacteria that has spread to the spleen, an organ that helps filter blood and fight infections. It's a form of extrapulmonary tuberculosis, meaning the infection has moved beyond the lungs to affect other parts of the body.

Coding Tips

  • This code should only be used when tuberculosis of the spleen is confirmed through clinical documentation, imaging, or pathology; do not code suspected or ruled-out cases
  • Verify that the documentation specifies splenic involvement and ensure this is not being confused with pulmonary TB or TB affecting other organs, which would require different codes
