About W16.331

W16.331 is the ICD-10-CM diagnosis code for fall into other water striking wall causing drowning and submersion. 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 3 subcodes must be used instead.

Within W16.33 (fall into other water striking wall), W16.331 is specifically for fall into other water striking wall causing drowning and submersion. Related codes cover causing other injury (W16.332).

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 W16.331 together with the conditions in its Excludes1 note: drowning and submersion while in other water without fall (W73).

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