V45.9XXAUnspecified car occupant injured in collision with railway train or railway vehicle in traffic accident, initial encounter

V45.9XXA is the ICD-10-CM diagnosis code for unspecified car occupant injured in collision with railway train or railway vehicle in traffic accident, initial encounter. It belongs to category V45 (car occupant injured in collision with railway train or railway vehicle), block V40-V49 (car 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 E810.9 (motor vehicle traffic accident involving collision with train injuring unspecified person).
