A18.10

What This Code Means

This code describes a tuberculosis infection affecting the genitourinary system (kidneys, bladder, reproductive organs) when the specific location is not documented. Tuberculosis is a serious bacterial infection that typically spreads through the lungs but can affect other body systems.

Coding Tips

• •Query the provider if a more specific site is documented (such as A18.11 for tuberculosis of kidney and ureter, or A18.12 for tuberculosis of bladder), as this unspecified code should only be used when the exact location cannot be determined
• •Ensure the patient has confirmed tuberculosis diagnosis and that this is not just a positive TB test; tuberculosis of the genitourinary system requires evidence of active disease in that organ system
