The ICD-10-CM code for Cyclic leukopenia is D70.0 (Congenital agranulocytosis).

Related codes cover agranulocytosis secondary to cancer chemotherapy (D70.1), other drug-induced agranulocytosis (D70.2), due to infection (D70.3), Cyclic neutropenia (D70.4), other neutropenia (D70.8) and unspecified (D70.9).
