ICD-10 code for agranulocytosis

About coding agranulocytosis
The ICD-10-CM code for agranulocytosis is D70.9 (Neutropenia, unspecified). The official index lists 8 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D70.9.
Within D70, choose D70.9 (unspecified) only when documentation doesn't support a more specific option: congenital agranulocytosis (D70.0), agranulocytosis secondary to cancer chemotherapy (D70.1), other drug-induced agranulocytosis (D70.2), due to infection (D70.3), Cyclic neutropenia (D70.4) and other neutropenia (D70.8).
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.
