W22 vs W64
W22 (Striking against or struck by other objects) compared with W64 (Exposure to other animate mechanical forces), 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. W22 carries an Excludes1 note covering W64: “contact or collision with animals or persons (W50-W64)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
