About W01
W01 is the ICD-10-CM diagnosis code for fall on same level from slipping, tripping and stumbling. It belongs to block W00-W19 (slipping, tripping, stumbling and falls) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: W01.0 (without subsequent striking against object) and W01.1 (with subsequent striking against object).
Don't report W01 together with the conditions in its Excludes1 note: fall due to bumping (striking) against object (W18.0-), fall in shower or bathtub (W18.2-), fall on same level NOS (W18.30), fall on same level from slipping, tripping and stumbling due to ice or snow (W00.0) and 3 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
