R55 vs R57.0
R55 (Syncope and collapse) compared with R57.0 (Cardiogenic shock), 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. R55 carries an Excludes1 note covering R57.0: “cardiogenic shock (R57.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
