Tuberculosis of spleen

This code represents a mycobacterial infection specifically affecting the spleen, caused by Mycobacterium tuberculosis. It signifies a localized manifestation of tuberculosis within the splenic parenchyma, which can occur as part of disseminated disease or, less commonly, as an isolated finding.

Use this code when diagnostic imaging (e.g., CT, MRI) or biopsy confirms the presence of tuberculosis within the spleen. Documentation should clearly indicate splenic involvement by M. tuberculosis, often presenting with splenomegaly, abdominal pain, or systemic symptoms of tuberculosis.

• Always code the underlying tuberculosis infection (e.g., A15-A19) as the primary diagnosis if the splenic involvement is a manifestation of a more widespread disease.
• Ensure documentation specifies "spleen" to differentiate from other intra-abdominal or lymphatic tuberculosis sites.
• Consider additional codes for any associated complications or co-existing conditions, such as ascites or lymphadenopathy, if documented.
