Whenever a work-related injury occurs, it ideally should be reported to the employer immediately. Next the MCO should be contacted. The injured worker, employer, or provider may report the claim to their MCO by phone, fax, mail, or on-line. WorkStar Health Services will gather the necessary information for claim filing through conferring with all parties of the claim (injured worker, employer, and provider), and report the information to the Ohio Bureau of Workers’ Compensation. For injury reporting, you may call WorkStar Health Services at 1-800-256-8833 or fax First Report of Injury form to 1-800-256-9940. Claims may also be reported on-line via www.ohiobwc.com.
