W18.3Other and unspecified fall on same level

W18.3 is the ICD-10-CM diagnosis code for other and unspecified fall on same level. 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, choose W18.3 (Other and unspecified fall on same level) only when documentation doesn't support a more specific option: fall due to bumping against object (W18.0), fall from or off toilet (W18.1), fall in (into) shower or empty bathtub (W18.2) 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.

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