About W10

W10 is the ICD-10-CM diagnosis code for fall on and from stairs and steps. 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 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: W10.0 (escalator), W10.1 (curb), W10.2 (incline), W10.8 (steps) and W10.9 (steps).

Don't report W10 together with the conditions in its Excludes1 note: Fall from stairs and steps due to ice and snow (W00.1).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
