W04 vs W28
W04 (Fall while being carried or supported by other persons) compared with W28 (Contact with powered lawn mower), 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. W04 carries an Excludes1 note covering W28: “fall (in) (from) machinery (in operation) (W28-W31)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
