About X96.2XXA

X96.2XXA is the ICD-10-CM diagnosis code for assault by letter bomb, initial encounter. It belongs to category X96 (assault by explosive material), block X92-Y09 (assault) 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 "A" means initial encounter: use it while the patient is receiving active treatment for the condition.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

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 E965.7 (assault by letter bomb).
