W01 vs W18.1
W01 (Fall on same level from slipping, tripping and stumbling) compared with W18.1 (Fall from or off toilet), 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. W01 carries an Excludes1 note covering W18.1: “fall off or from toilet (W18.1-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
