About W16.02

W16.02 is the ICD-10-CM diagnosis code for fall into swimming pool striking bottom. It belongs to category W16 (fall, jump or diving into water), 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 2 subcodes must be used instead.

Within W16.0 (fall into swimming pool), W16.02 is specifically for fall into swimming pool striking bottom. Related codes cover striking water surface (W16.01) and striking wall (W16.03).

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.
