About the B65–B83 Code Range
ICD-10 codes B65 through B83 cover a group of parasitic infections caused by helminths, which are parasitic worms. These codes are specifically used to classify diseases such as schistosomiasis, fluke infections, tapeworm infections, filariasis, and other related worm infestations.
This range includes B65 for various forms of schistosomiasis, also known as bilharziasis, with distinctions made for infections by different Schistosoma species causing urinary, intestinal, or hepatic symptoms. For example, B65.0 describes urinary schistosomiasis (Schistosoma haematobium), while B65.1 refers to intestinal schistosomiasis (Schistosoma mansoni). Codes B66 to B69 identify infections by various flukes and cestodes (tapeworms), such as Clonorchiasis (B66.1) and Taeniasis (B68), which include conditions like cysticercosis with central nervous system involvement (B69.0). Filariasis and related infections are coded under B74, covering diseases like lymphatic filariasis caused by Wuchereria bancrofti (B74.0). Other notable infections like strongyloidiasis (B78), enterobiasis (B80), and additional specified and unspecified helminthiases are also included. These codes help in accurately identifying and reporting a wide spectrum of parasitic worm infections with diverse clinical manifestations affecting various organs.
