Ancylostomiasis

This code represents an infection of the small intestine caused by hookworms, specifically Ancylostoma duodenale or Ancylostoma ceylanicum. The parasites attach to the intestinal wall, feeding on blood and causing symptoms such as anemia, abdominal pain, and malnutrition.

Use this code when documentation confirms a diagnosis of hookworm infection due to Ancylostoma species. This diagnosis is typically established through microscopic examination of stool samples revealing hookworm eggs or larvae. It is commonly seen in patients from endemic regions with poor sanitation.

• Do not confuse with Necatoriasis (B76.1), which is caused by Necator americanus.
• Ensure the documentation specifies Ancylostoma species to differentiate from other hookworm infections.
• Consider co-occurring conditions like iron deficiency anemia (D50.0-D50.9) often associated with chronic hookworm infection.
