About V25.21XA

V25.21XA is the ICD-10-CM diagnosis code for unspecified electric (assisted) bicycle rider injured in collision with railway train or railway vehicle in nontraffic accident, initial encounter. It belongs to category V25 (motorcycle rider injured in collision with railway train or railway vehicle), 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 "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 was added in FY2023, effective October 1, 2022.
