About W65.XXXD
W65.XXXD is the ICD-10-CM diagnosis code for accidental drowning and submersion while in bath-tub, subsequent encounter. It belongs to category W65 (accidental drowning and submersion while in bath-tub), block W65-W74 (accidental non-transport drowning and submersion) and chapter 20 (external causes of morbidity). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
The 7th character "D" means subsequent encounter: use it for encounters after active treatment, while the patient is healing or recovering.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as E910.4 (accidental drowning and submersion in bathtub).
