About Y38.2X1S

Y38.2X1S is the ICD-10-CM diagnosis code for terrorism involving other explosions and fragments, public safety official injured, sequela. 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 "S" means sequela: use it for complications or conditions that arise as a direct result of the original condition.

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 E999.1 (late effect of injury due to terrorism).
