Medical bills related to your work injury are paid by Chubb. Medical bills should be sent to Chubb as soon as you receive them. Using your claim number, you can upload your medical bills directly through our online application by clicking here. If you would like to forward your medical bills via mail or fax, please contact your adjuster for the appropriate mailing address and fax number. Be sure to include your claim number on any documents you send. You should also provide your claim number and the billing information to each medical provider and inform them that you have a workers compensation claim.
