Myelodysplasia

Myelodysplasia is used to describe a group of disorders that result in the inability to produce enough healthy mature blood cells. Myelodysplasia can occur with benign (non-reportable) or malignant (reportable) diseases. The diagnosis of myelodysplasia by itself is not reportable because the term includes both non-malignancies and malignancies. Follow-back to the physician is necessary to determine whether or not this is a malignancy.


Non-reportable disorders include: Anemia, leukopenia and thrombocytopenia.

Reportable disorders include: MDS, refractory anemia, refractory anemia with excess blasts in transformation, refractory anemia with ring sideroblasts, refractory anemia with excess blasts, chronic myelomonocytic leukemia and acute myeloid leukemia.

Myelodysplasia and myelodysplastic syndrome (9989/3) are not the same disease. Myelodysplasia may be used as an alternate names for myelodysplastic syndrome; however, the terms MDS, or myelodysplastic syndrome should be used somewhere in the medical record
