A18.7

What This Code Means

This is a serious infection caused by tuberculosis bacteria that affects the adrenal glands, which are small glands that sit on top of the kidneys and produce important hormones. This condition is a form of extrapulmonary tuberculosis (TB occurring outside the lungs) and can lead to adrenal insufficiency if not treated.

Coding Tips

• •This code should only be used when tuberculosis of the adrenal glands is confirmed through culture, histology, or clinical/radiological evidence; do not use for suspected cases without confirmation
• •Code A18.7 is part of the extrapulmonary TB category; ensure the primary TB site is documented and coded separately if pulmonary TB is also present, as this affects the severity and treatment approach
