C95.0 vs C95.10
C95.0 (Acute leukemia of unspecified cell type) compared with C95.10 (Chronic leukemia of unspecified cell type not having achieved remission), 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. C95.0 carries an Excludes1 note covering C95.10: “acute exacerbation of unspecified chronic leukemia (C95.10)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
