Pinnacol asks first-time billers to complete a W-9 and fax it (with the bill) to this number. Payment-setup paperwork only; not a place for claims 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.
