Schistosomiasis, unspecified

This code represents an infection caused by parasitic flatworms of the genus Schistosoma, where the specific species of the parasite is not identified. It encompasses the systemic inflammatory response and organ damage that can result from schistosomiasis when the causative agent is unknown.

This code is appropriate when a patient is diagnosed with schistosomiasis, but the medical record does not specify the particular Schistosoma species (e.g., S. mansoni, S. haematobium, S. japonicum). It should be used when diagnostic testing confirms schistosomiasis, but further speciation is either not performed or not documented.

• Avoid using this code if the specific Schistosoma species is documented; instead, use the more specific code from the B65.0-B65.8 range.
• Consider sequencing this code after any associated organ manifestations (e.g., hepatic fibrosis, bladder calcification) if they are documented as a direct result of the schistosomiasis.
• Ensure documentation clearly states a diagnosis of schistosomiasis without further species identification to support the use of this unspecified code.
