About coding secondary agranulocytosis

The ICD-10-CM code for secondary agranulocytosis is D70.4 (Cyclic neutropenia). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D70.4.

Within D70 (neutropenia), D70.4 is specifically for Cyclic neutropenia. Related codes cover congenital agranulocytosis (D70.0), agranulocytosis secondary to cancer chemotherapy (D70.1), other drug-induced agranulocytosis (D70.2), due to infection (D70.3), other neutropenia (D70.8) and unspecified (D70.9).

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.
