Strongyloidiasis (B78)
ICD-10 codes for Strongyloidiasis (B78) classify infections caused by the parasitic worm Strongyloides. These codes help specify whether the infection affects the intestines, skin, is widely spread, or remains unspecified, guiding accurate diagnosis and treatment.
The main code B78 covers all cases of strongyloidiasis, while B78.0 is used for intestinal strongyloidiasis, also called Strongyloides duodenitis, which involves inflammation of the small intestine and can affect the colon. The code B78.1 specifies cutaneous strongyloidiasis, characterized by skin infections such as strongyloidal ground itch or urticaria caused by Strongyloides stercoralis larvae. For cases where the infection spreads beyond the intestines and skin, B78.7 denotes disseminated strongyloidiasis, often occurring alongside immunosuppressive conditions like HIV. If the infection cannot be further classified, B78.9 captures unspecified strongyloidiasis, encompassing various clinical presentations including neurological or glomerular complications due to Strongyloides.
Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Strongyloides
A genus of parasitic nematodes widely distributed as intestinal parasites of mammals.
Strongyloidiasis
Infection with nematodes of the genus STRONGYLOIDES. The presence of larvae may produce pneumonitis and the presence of adult worms in the intestine could lead to moderate to severe diarrhea.
