Encntr screen for oth protozoal diseases and helminthiases

This code signifies a patient encounter specifically for the purpose of screening for parasitic infections caused by protozoa or helminths, excluding those affecting the intestinal tract. It is used when a patient is asymptomatic but is being tested due to risk factors or public health initiatives.

Apply this code when a patient undergoes screening tests for conditions like malaria, Chagas disease, toxoplasmosis, or filariasis, without presenting with symptoms of these diseases. This often occurs in individuals traveling to endemic areas, immigrants, or during public health screening programs.

• Ensure the documentation clearly states "screening" and specifies the type of parasitic disease being screened for, if known.
• Do not use this code if the patient has symptoms or a confirmed diagnosis of a protozoal or helminthic disease; instead, code the specific condition.
• Remember the Excludes2 note: for screening of intestinal protozoal diseases, refer to Z11.0.
