All medical-treatment-related bills

ICW Group's workers' compensation claims FAQ: send all medical-treatment-related bills to the Clinton, Iowa P.O. box. Other claim-related bills and reimbursement requests use a different San Diego P.O. box or fax and are not medical bills. The page also gives 800.877.1111 for questions the FAQ does not answer. 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.
