When you are injured and you or the at-fault party have insurance available for the injury, subrogation is a way to reimburse your health plan for all or some of the claims your health plan has paid related to the injury. Common cases are:

Work-related injuries
Motor vehicle accidents (whether you are hurt in or around a vehicle)
Slip and fall injuries on someone else’s property (such as a store)

If you are ever injured, let HPSM know right away by calling the number for your health plan below
