About W13

W13 is the ICD-10-CM diagnosis code for fall from, out of or through building or structure. 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: W13.0 (balcony), W13.1 (bridge), W13.2 (roof), W13.3 (floor), W13.4 (window), W13.8 (structure) and W13.9 (specified).

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