W03.XXXD vs Y01
W03.XXXD (Other fall on same level due to collision with another person, subsequent encounter) compared with Y01 (Assault by pushing from high place), 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. W03.XXXD carries an Excludes1 note covering Y01: “assault involving a fall (Y01-Y02)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
