Definitions from the National Library of Medicine for conditions coded in the B76 range.
Ancylostoma
A genus of nematode intestinal parasites that consists of several species. A. duodenale is the common hookworm in humans. A. braziliense, A. ceylonicum, and A. caninum occur primarily in cats and dogs, but all have been known to occur in humans.
Ancylostomiasis
Infection of humans or animals with hookworms of the genus ANCYLOSTOMA. Characteristics include anemia, dyspepsia, eosinophilia, and abdominal swelling.
Necatoriasis
Infection of humans or animals with hookworms of the genus NECATOR. The resulting anemia from this condition is less severe than that from ANCYLOSTOMIASIS.
About the B76 Code Range
The ICD-10 code B76 represents hookworm diseases, parasitic infections caused by various hookworm species. These codes classify specific types of hookworm infections such as Ancylostomiasis (B76.0) and Necatoriasis (B76.1), as well as other less common or unspecified hookworm conditions.
These codes are used to document infections caused by hookworms like Ancylostoma and Necator americanus. For example, B76.0 covers conditions also known as Ancylostomiasis, which include inflammation and eosinophilic enteritis of the small intestine caused by species such as Ancylostoma caninum or Ancylostoma braziliense. This code also relates to cutaneous larva migrans, a skin condition caused by hookworm larvae. The code B76.1 identifies Necatoriasis, a parasitic infection specifically caused by Necator americanus. Code B76.8 includes other hookworm-related illnesses, such as infections by Uncinaria or Gnathostoma, which may present as visceral larva migrans syndrome. Lastly, B76.9 is used when the hookworm disease is unspecified. These ICD-10 codes for hookworm diseases help medical coders and healthcare providers accurately capture the exact type of parasitic infection for diagnosis, treatment, and reporting purposes.
