About W74

W74 is the ICD-10-CM diagnosis code for unspecified cause of accidental drowning and submersion. It belongs to block W65-W74 (accidental non-transport drowning and submersion) 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: W74.XXXA (initial encounter), W74.XXXD (subsequent encounter) and W74.XXXS (sequela).

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