Neutropenia (D70) ICD-10-CM
The D70 code range covers neutropenia with 8 ICD-10-CM diagnosis codes. 7 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- agranulocytosis
- decreased absolute neurophile count (ANC)
Code Also
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
- code for any associated:
- fever R50.81
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the D70 Code Range
Neutropenia means a decreased number of neutrophils in the blood. Its codes distinguish the conditions named in the subdivisions and their stated causes.
D70.0 identifies congenital agranulocytosis. D70.1 identifies agranulocytosis secondary to cancer chemotherapy, while D70.2 identifies other drug-induced agranulocytosis. D70.3 identifies neutropenia due to infection, and D70.4 identifies cyclic neutropenia. Separate codes identify other neutropenia (D70.8) and unspecified neutropenia (D70.9).
