Medical re-imburs plans in additikon to a regular medical plan ?

My insurance is Aetna Healthcare. It WILL not cover WLS because of the plan we have.  My work picked up a "medcal Re-Imbursement " plan to try to help me re-cover some of the costs associated with my self pay.   The owner ( my lovely mother) signed up 5 of us.  The costis 250 $ per year per person and it's "SUPPOSED " to re-imburse up to 10K for various procedures and WLS is specified as ONEOF THEM.   Can someone maybe explain how these programs work ? While the idea of something so cheap re-imbursing me that much is ridiculous, I hope it's somewhat true ??
