Other disorders of white blood cells (D72) ICD-10-CM
The D72 code range covers other disorders of white blood cells with 28 ICD-10-CM diagnosis codes. 22 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
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.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the D72 range.
Eosinophilia
Abnormal increase of EOSINOPHILS in the blood, tissues or organs.
Hypereosinophilic Syndrome
A syndrome characterized by persistent eosinophilia, for which no underlying cause can be found, and which is associated with signs of organ involvement and dysfunction. This term has often been applied to cases of chronic eosinophilic leukemia. (WHO, 2001)
Leukemoid Reaction
A peripheral blood picture resembling that of leukemia or indistinguishable from it on the basis of morphologic appearance alone. (Dorland, 27th ed)
Leukocytosis
A transient increase in the number of leukocytes in a body fluid.
Leukopenia
A decrease in the number of LEUKOCYTES in a blood sample below the normal range (LEUKOCYTE COUNT less than 4000).
Lymphocytic Variant Hypereosinophilic Syndrome
A hypereosinophilic syndrome characterized by the presence of a clonal T-cell population. Patients present with cutaneous findings including eczematous dermatitis, nodules, papules, and pruritis, rheumatological symptoms, gastrointestinal symptoms, and lymphadenopathy. Lymph node biopsies show eosinophilia, atypical lymphocytes, clonally rearranged T-cells, and architectural distortion. Skin biopsies may also show the clonally rearranged T-cell population.
Lymphocytosis
Excess of normal lymphocytes in the blood or in any effusion.
Lymphopenia
Reduction in the number of lymphocytes.
Plasmacytosis
A morphologic finding indicating the presence of plasma cell infiltrates in tissues, or the presence of plasma cells in the peripheral blood.
About the D72 Code Range
These disorders affect white blood cells. They include genetic anomalies, eosinophilia, and decreased or elevated white blood cell counts.
D72.0 identifies genetic anomalies. D72.1 groups eosinophilia by named syndrome or type, other type, and unspecified type. Within it, D72.11 separates named, other, and unspecified forms of hypereosinophilic syndrome.
D72.8 groups other specified white blood cell disorders. Its subdivisions separate decreased from elevated counts, then distinguish named findings from other and unspecified findings. D72.9 identifies an unspecified white blood cell disorder.
