W18.09 vs W22
W18.09 (Striking against other object with subsequent fall) compared with W22 (Striking against or struck by other objects), 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 W18.09: “striking against or struck by object with subsequent fall (W18.09)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
