V79.20XAUnspecified bus occupant injured in collision with unspecified motor vehicles in nontraffic accident, initial encounter

V79.20XA is the ICD-10-CM diagnosis code for unspecified bus occupant injured in collision with unspecified motor vehicles in nontraffic accident, initial encounter. It belongs to category V79 (bus occupant injured in other and unspecified transport accidents), 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 E822.9 (other motor vehicle nontraffic accident involving collision with moving object injuring unspecified person).
