D72Other disorders of white blood cells

D72 is the ICD-10-CM diagnosis code for other disorders of white blood cells. 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 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: D72.0 (leukocytes), D72.1 (eosinophilia), D72.8 (cells) and D72.9 (unspecified).

Don't report D72 together with the conditions in its Excludes1 note: basophilia (D72.824), immunity disorders (D80-D89) and preleukemia (syndrome) (D46.9).

The conditions in its Excludes2 note aren't part of D72, but may be coded alongside it if the patient has both: neutropenia (D70).

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