About D70

D70 is the ICD-10-CM diagnosis code for neutropenia. It belongs to block D70-D77 (other disorders of blood and blood-forming organs) and chapter 3 (diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D70.0 (agranulocytosis), D70.1 (chemotherapy), D70.2 (agranulocytosis), D70.3 (due to infection), D70.4 (neutropenia), D70.8 (neutropenia) and D70.9 (unspecified).

Don't report D70 together with the conditions in its Excludes1 note: neutropenic splenomegaly (D73.81) and transient neonatal neutropenia (P61.5).

Use an additional code for any associated: fever (R50.81).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
