About W17.3XXD
W17.3XXD is the ICD-10-CM diagnosis code for fall into empty swimming pool, subsequent encounter. It belongs to category W17 (other fall from one level to another), block W00-W19 (slipping, tripping, stumbling and falls) 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 E883.9 (accidental fall into other hole or other opening in surface).
