Ancylostomiasis due to ancylostoma ceylanicum

This code identifies an infection caused by the hookworm Ancylostoma ceylanicum. This parasitic infection typically affects the small intestine, leading to symptoms such as abdominal pain, diarrhea, and iron deficiency anemia due to chronic blood loss.

Use this code when documentation specifically identifies ancylostomiasis and further specifies the causative agent as Ancylostoma ceylanicum. This diagnosis is often confirmed through microscopic examination of stool samples revealing characteristic hookworm eggs or adult worms.

• Ensure the documentation explicitly states Ancylostoma ceylanicum as the etiologic agent; otherwise, a more general ancylostomiasis code may be appropriate.
• Code any associated manifestations, such as iron deficiency anemia (e.g., 280.0), as secondary diagnoses.
• Distinguish from other hookworm infections like those caused by Ancylostoma duodenale or Necator americanus, which have different specific codes.
