What that means for your claim

Gallagher Bassett runs the claim. It does not fund it. A third-party administrator is an agent under contract to administer the claims of an insurer, a self-insured employer, a legally uninsured employer or a self-insured joint powers authority.

The person handling your claim works for the payer, not for you. Every benefit notice must tell you that you have a right to disagree with decisions affecting your claim and a right to be represented by an attorney of your choice.
