What This Code Means

Mansonelliasis is a parasitic infection caused by Mansonella worms, which are transmitted through insect bites and can cause skin irritation, itching, and other symptoms. This is a tropical disease primarily found in Africa and South America.

Coding Tips

• •Verify the specific type of Mansonella infection (M. streptocerca, M. ozzardi, or M. perstans) in the medical record, as some may have more specific codes available
• •Document the geographic location or travel history to endemic areas, as this supports medical necessity and helps establish the diagnosis
