D46

Myelodysplastic syndromes

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 9 more specific codes instead:

  • D46.0 Refractory anemia without ring sideroblasts, so stated
  • D46.1 Refractory anemia with ring sideroblasts
  • D46.2 Refractory anemia with excess of blasts [RAEB] (also a header)
  • D46.4 Refractory anemia, unspecified
  • D46.9 Myelodysplastic syndrome, unspecified
  • D46.A Refractory cytopenia with multilineage dysplasia
  • D46.B Refractory cytopenia with multilineage dysplasia and ring sideroblasts
  • D46.C Myelodysplastic syndrome with isolated del(5q) chromosomal abnormality
  • D46.Z Other myelodysplastic syndromes

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

  1. FY2012 Added to the draft code set draft Myelodysplastic syndromes
