Echinococcus granulosus infection, multiple sites

This code identifies an infection caused by the larval stage of the tapeworm Echinococcus granulosus, specifically when the parasitic cysts are found in two or more distinct anatomical locations within the patient's body. This condition, also known as multi-organ cystic echinococcosis or hydatid disease, results from the ingestion of Echinococcus granulosus eggs.

Use this code when diagnostic imaging (e.g., ultrasound, CT, MRI) or surgical findings confirm the presence of hydatid cysts in multiple organs, such as the liver and lungs, or liver and brain. Documentation must clearly indicate the involvement of more than one site to support the use of this specific code.

• Ensure documentation explicitly states "multiple sites" or lists at least two distinct affected organs.
• Do not confuse with single-site echinococcosis codes (e.g., B67.0x, B67.1x, B67.2x).
• Code any associated complications (e.g., rupture, secondary infection) separately, if documented.
