W18.11Fall from or off toilet without subsequent striking against object

W18.11 is the ICD-10-CM diagnosis code for fall from or off toilet without subsequent striking against object. It belongs to category W18 (other slipping, tripping and stumbling and falls), 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 W18.1, choose W18.11 (without subsequent striking against object) only when documentation doesn't support a more specific option: with subsequent striking against object (W18.12).

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.
