AmTrust asks medical providers and vendors to return the ACH enrollment form, signed W-9 and bank verification document to this address (one form per TIN). For payment setup only, not bill submission or claim questions. Workers' compensation: a claim number and the adjuster or injured-worker identification are usually required; coverage is determined by the claim (not by a member ID), and state fee schedules and rules govern billing.
