Other anemias (D64) ICD-10-CM

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 II is the most common of the 3 types; it is often referred to as HEMPAS, based on the Hereditary Erythroblast Multinuclearity with Positive Acidified Serum test.

About the D64 Code Range
These anemias include inherited forms, forms linked to disease or drugs and toxins, and forms identified by another type or cause.

Within other specified anemias, D64.81 identifies anemia due to antineoplastic chemotherapy, while D64.89 identifies other specified anemias. D64.9 identifies anemia without a specified type.
