Myelodysplastic syndrome with isolated del(5q) chromosomal abnormality
ValidICD-10-CM diagnosis code.
Valid for claims with a date of service in the current code year.
What has happened to this code
Every change the publisher made, from 2010 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.
- FY2010 Added to the draft code set draft Myelodysplastic syndrome with isolated del(5q) chromosomal abnormality
Official coding rules
Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
Inherited from D46 Myelodysplastic syndromes
Excludes2 - not included here
- drug-induced aplastic anemia (D61.1)
Use additional code
- code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
Inherited from the D37-D48 section Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes (D37-D48)
Excludes1 - never coded here
- neoplasms of unspecified behavior (D49.-)
Note
- Categories D37-D44, and D48 classify by site neoplasms of uncertain behavior, i.e., histologic confirmation whether the neoplasm is malignant or benign cannot be made.
