Necatoriasis

This code represents an intestinal infection caused by the hookworm Necator americanus. The parasites attach to the small intestine, feeding on blood and causing symptoms such as anemia, abdominal pain, and malnutrition.

Use this code when documentation confirms a diagnosis of necatoriasis, typically identified through microscopic examination of stool samples for hookworm eggs. This diagnosis is common in tropical and subtropical regions with poor sanitation.

• Differentiate from other hookworm infections (e.g., Ancylostoma duodenale) which have separate codes.
• Consider co-occurring conditions like iron deficiency anemia, which is a common complication and should be coded separately.
• Ensure the documentation specifies Necator americanus if possible, though "necatoriasis" alone is sufficient for this code.
