D46.2Refractory anemia with excess of blasts [RAEB]

D46.2 is the ICD-10-CM diagnosis code for refractory anemia with excess of blasts [RAEB]. It belongs to category D46 (myelodysplastic syndromes), block D37-D48 (neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within D46 (myelodysplastic syndromes), D46.2 is specifically for refractory anemia with excess of blasts [RAEB]. Related codes cover refractory anemia without ring sideroblasts, so stated (D46.0), refractory anemia with ring sideroblasts (D46.1), refractory anemia, unspecified (D46.4), myelodysplastic syndrome, unspecified (D46.9), refractory cytopenia with multilineage dysplasia (D46.A), refractory cytopenia with multilineage dysplasia and ring sideroblasts (D46.B), myelodysplastic syndrome with isolated del(5q) chromosomal abnormality (D46.C) and other myelodysplastic syndromes (D46.Z).

To report this condition, pick the subcode that matches the documentation: D46.20 (unspecified), D46.21 (1) and D46.22 (2).

Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (title revised).
