About W18
W18 is the ICD-10-CM diagnosis code for other slipping, tripping and stumbling and falls. 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: W18.0 (object), W18.1 (toilet), W18.2 (bathtub), W18.3 (level) and W18.4 (falling).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
