About V21.91XD

V21.91XD is the ICD-10-CM diagnosis code for unspecified electric (assisted) bicycle rider injured in collision with pedal cycle in traffic accident, subsequent encounter. It belongs to category V21 (motorcycle rider injured in collision with pedal cycle), block V20-V29 (motorcycle rider 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 was added in FY2023, effective October 1, 2022.
