What is the correct code for an office visit to screen a patient for anemia?

A) Z13.88
B) Z13.0
C) Z13.9
D) Z13.6

The correct code for an office visit to screen a patient for anemia is Z13.0 - Encounter for screening for disorders of the blood and blood-forming organs and immune mechanisms. Z13.0 is the appropriate code for encounters for screening for conditions that are not currently causing symptoms or for patients with no known exposure to the condition being screened for. Anemia is a disorder of the blood and blood-forming organs, so Z13.0 is the most specific code for this type of encounter.
