C92.1 vs C93.1
C92.1 (Chronic myeloid leukemia, BCR/ABL-positive) compared with C93.1 (Chronic myelomonocytic leukemia), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. C92.1 carries an Excludes1 note covering C93.1: “chronic myelomonocytic leukemia (C93.1-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
