What's subrogation?

Subrogation is the process of getting the responsible party's insurance company to pay when someone is injured.

How it works

Subrogation protects members from paying medical costs that should be paid by whoever is responsible. Situations that may lead to subrogation include:

  • Being involved in a car accident that isn’t your fault
  • Being injured on the job
  • Someone hurts you; this is a personal injury
  • A doctor does something that hurts you; this could be medical malpractice

If you've gotten a subrogation letter from Blue Cross, then your next step is to log in and fill out the subrogation form.

What if I haven't received a subrogation letter?

You can request a subrogation letter by describing your injury in the subrogation request questionnaire and sending it to Blue Cross.
