About W03

W03 is the ICD-10-CM diagnosis code for other fall on same level due to collision with another person. It belongs to 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.

To report this condition, pick the subcode that matches the documentation: W03.XXXA (initial encounter), W03.XXXD (subsequent encounter) and W03.XXXS (sequela).

Don't report W03 together with the conditions in its Excludes1 note: collision with another person without fall (W51), crushed or pushed by a crowd or human stampede (W52), fall involving pedestrian conveyance (V00-V09), fall due to ice or snow (W00) and 1 more.

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