About W18.2

W18.2 is the ICD-10-CM diagnosis code for fall in (into) shower or empty bathtub. 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 (other slipping, tripping and stumbling and falls), W18.2 is specifically for fall in (into) shower or empty bathtub. Related codes cover fall due to bumping against object (W18.0), fall from or off toilet (W18.1), other and unspecified fall on same level (W18.3) and slipping, tripping and stumbling without falling (W18.4).

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.

Don't report W18.2 together with the conditions in its Excludes1 note: fall in full bathtub causing drowning or submersion (W16.21-).

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