Echinococcus granulosus infection, other sites

This code signifies an infection caused by the larval stage of the tapeworm Echinococcus granulosus, commonly known as hydatid disease or cystic echinococcosis, when the parasitic cysts are located in organs or tissues other than the liver or lung. These "other sites" can include the brain, bone, spleen, kidney, or heart.

Use this code when diagnostic imaging (e.g., CT, MRI, ultrasound) or histopathology confirms the presence of Echinococcus granulosus cysts in an extrahepatic, extrapulmonary location. Documentation should clearly specify the affected anatomical site(s) beyond the liver and lungs.

• Do not use for liver (B67.0) or lung (B67.1) involvement; specific codes exist for these sites.
• Ensure documentation specifies the exact "other site" for optimal specificity and to support medical necessity.
• Consider sequencing with codes for associated symptoms or complications, such as organ dysfunction, if applicable.
