W18.09Striking against other object with subsequent fall

W18.09 is the ICD-10-CM diagnosis code for striking against other object with subsequent fall. 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 W18.0, choose W18.09 (other object with subsequent fall) only when documentation doesn't support a more specific option: unspecified object with subsequent fall (W18.00), sports equipment with subsequent fall (W18.01) and glass with subsequent fall (W18.02).

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.
