About Y38.0X2D
Y38.0X2D is the ICD-10-CM diagnosis code for terrorism involving explosion of marine weapons, civilian injured, subsequent encounter. It belongs to category Y38 (terrorism), block Y35-Y38 (legal intervention, operations of war, military operations, and terrorism) 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.
Use an additional code for place of occurrence (Y92.-).
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 E979.0 (terrorism involving explosion of marine weapons).
