V74.4XXAPerson boarding or alighting from bus injured in collision with heavy transport vehicle or bus, initial encounter

V74.4XXA is the ICD-10-CM diagnosis code for person boarding or alighting from bus injured in collision with heavy transport vehicle or bus, initial encounter. It belongs to category V74 (bus occupant injured in collision with heavy transport vehicle or bus), 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 E824.8 (other motor vehicle nontraffic accident while boarding and alighting injuring other specified person).
