Macrocytosis ICD-10-CM Codes

A macrocytosis ICD code should be used when a patient's blood test reveals the presence of abnormally large red blood cells and when there is a related medical diagnosis.

Treatment usually targets the underlying cause. This could range from vitamin supplementation (in the case of deficiency) to medication adjustments or addressing liver disease or alcohol consumption.

A diagnosis code for macrocytosis signifies the presence of larger-than-normal red blood cells in a patient, which can indicate various underlying conditions.
