V44.6XXDCar passenger injured in collision with heavy transport vehicle or bus in traffic accident, subsequent encounter

V44.6XXD is the ICD-10-CM diagnosis code for car passenger injured in collision with heavy transport vehicle or bus in traffic accident, subsequent encounter. It belongs to category V44 (car occupant injured in collision with heavy transport vehicle or bus), 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 "D" means subsequent encounter: use it for encounters after active treatment, while the patient is healing or recovering.

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 E812.1 (other motor vehicle traffic accident involving collision with motor vehicle injuring passenger in motor vehicle other than motorcycle).
