Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the B70 range.
Diphyllobothriasis
Infection with tapeworms of the genus Diphyllobothrium.
Sparganosis
Infection of animals, including fish and man, with a developmental stage of Diphyllobothrium. This stage has recently been referred to as a plerocercoid but the name sparganum has persisted. Therefore, infection of fish or other animals with the plerocercoid larvae is sparganosis. Fish-eating mammals, including man, are the final hosts.
About the B70 Code Range
ICD-10 code B70 is used to classify infections caused by specific tapeworm parasites, including both diphyllobothriasis (B70.0) and sparganosis (B70.1). These codes help healthcare providers document and report cases of these rare parasitic diseases effectively.
Diphyllobothriasis refers to the infection caused by tapeworms of the Diphyllobothriidae family, also known by names such as "infection by Diphyllobothrium latum," "intestinal diphyllobothriasis," or "megaloblastic anemia caused by fish tapeworm." This condition results from ingesting larvae through undercooked fish. In contrast, sparganosis involves infection by the larvae of Spirometra species and is sometimes called "infection by Spirometra larvae" or "dermatosis caused by tapeworm." Sparganosis often affects the skin or subcutaneous tissues. Understanding the synonyms connected to these infections helps medical coders accurately select ICD-10 code B70 when encountering related terms during diagnosis or documentation.
