Pinnacol's published customer service line. Pinnacol's provider pages direct providers here when a bill has gone more than 30 days without an explanation of review. Toll-free 800.873.7242 and toll-free fax 888.329.2251 also appear on the contact page. 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.
