Q92.2 vs Q92.5
Q92.2 (Partial trisomy) compared with Q92.5 (Duplications with other complex rearrangements), 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. Q92.2 carries an Excludes1 note covering Q92.5: “partial trisomy due to unbalanced translocation (Q92.5)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
