About W00.1

W00.1 is the ICD-10-CM diagnosis code for fall from stairs and steps due to ice and snow. It belongs to category W00 (fall due to ice and snow), 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 3 subcodes must be used instead.

Within W00 (fall due to ice and snow), W00.1 is specifically for fall from stairs and steps due to ice and snow. Related codes cover fall on same level due to ice and snow (W00.0), other fall from one level to another due to ice and snow (W00.2) and unspecified fall due to ice and snow (W00.9).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

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