I had a sports-related injury a few months back, and I recently received a letter from a company named Vengroff, Williams & Assoc. asking me to self-report if the injury was due to a third party, and if so provide details. It goes on to state in extended legalese that I agree to reimburse the FedEx/Anthem plan any benefits or damages I receive from a third party. It also threatens that if they don't receive the requested info, my "medical bills related to any claim may not be considered for payment."

None of this applies in my case since there wasn't a third party involved in my injury, but am I even obligated to fill out & return this form? I haven't heard anything back from ALPA R&I folks on the matter, but I generally don't like the idea of agreeing to legally-binding Subrogation Agreements I just randomly receive in the mail...
