G25.5 vs R25.1
G25.5 (Other chorea) compared with R25.1 (Tremor, unspecified), 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. R25.1 carries an Excludes1 note covering G25.5: “chorea NOS (G25.5)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
