Echinococcosis, unspecified, of liver

This code represents an unspecific form of echinococcosis, a parasitic infection caused by tapeworm larvae, affecting the liver. It indicates the presence of hydatid cysts or other manifestations of echinococcal disease within the hepatic parenchyma without further specification of the causative Echinococcus species.

Use this code when documentation confirms echinococcal infection of the liver but does not specify the species (e.g., Echinococcus granulosus or Echinococcus multilocularis). This code is appropriate when imaging studies (ultrasound, CT, MRI) or serological tests indicate hepatic echinococcosis, but the specific type of echinococcosis is not yet determined or documented.

• Always seek clarification from the provider if the specific Echinococcus species is known, as more specific codes exist (e.g., B67.0, B67.1).
• Do not use this code if the echinococcosis is specified as due to Echinococcus granulosus or Echinococcus multilocularis.
• Consider sequencing this code after any codes for associated complications, such as liver abscess (K75.0) or biliary obstruction (K83.01), if applicable.
