About coding chemotherapy induced leukopenia
The ICD-10-CM code for chemotherapy induced leukopenia is D70.1 (Agranulocytosis secondary to cancer chemotherapy).
Within D70 (neutropenia), D70.1 is specifically for agranulocytosis secondary to cancer chemotherapy. Related codes cover congenital agranulocytosis (D70.0), other drug-induced agranulocytosis (D70.2), due to infection (D70.3), Cyclic neutropenia (D70.4), other neutropenia (D70.8) and unspecified (D70.9).
Use an additional code for adverse effect, if applicable, to identify drug (T45.1X5). Use an additional code for any associated: fever (R50.81).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
