About W32.1XXD
W32.1XXD is the ICD-10-CM diagnosis code for accidental handgun malfunction, subsequent encounter. It belongs to category W32 (accidental handgun discharge and malfunction), block W20-W49 (exposure to inanimate mechanical forces) 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 E922.0 (accident caused by handgun).
