About Y04.2XXS
Y04.2XXS is the ICD-10-CM diagnosis code for assault by strike against or bumped into by another person, sequela. It belongs to category Y04 (assault by bodily force), 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 "S" means sequela: use it for complications or conditions that arise as a direct result of the original condition.
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 E969 (late effects of injury purposely inflicted by other person).
