About V78.9XXA
V78.9XXA is the ICD-10-CM diagnosis code for unspecified occupant of bus injured in noncollision transport accident in traffic accident, initial encounter. It belongs to category V78 (bus occupant injured in noncollision transport accident), block V70-V79 (bus occupant injured in transport accident) 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 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 E816.9 (motor vehicle traffic accident due to loss of control, without collision on the highway, injuring unspecified person).
