    Our knowledge and expertise – combined with a powerful coverage solution – can help prevent injuries to your employees by promoting safe operations and help protect your business by effectively addressing injuries when they occur. To manage workers compensation costs once injuries occur, we recommend:

    1. Prompt, caring responses to injuries.
    2. Channeling injured employees to appropriate medical providers.
    3. Immediately reporting the claim to OneBeacon.
    4. Providing transitional duty options for a prompt return to work.
    5. Containing medical costs.

    Injury Response

    Adopt a formal program for both point-of-injury response and post-injury follow-up and contact.  This includes displaying a positive and concerned response to an injury and maintaining regular contact with the employee until he or she is back on the job.

    Channeling to Medical Providers

    Promote and publicize your Medical Provider Panel before workplace injuries occur. Ensure your Supervisors and Managers are familiar with the designated medical providers and train them to recommend the Occupational Medicine provider for initial care in non-emergency situations.


    On-the-job accidents can occur despite an employer’s best efforts to avoid them. In the event of an injury, it is critical to report the claim immediately.  Early reporting means earlier care and more controlled costs. For guidance with reporting a claim, use our Workers Compensation Reporting Checklist.

    Return to Work

    OneBeacon manages workers compensation claims to promote your employee’s recovery and quickest possible return to work.  OneBeacon also works directly with employers to return employees to transitional work whenever possible.  Getting injured employees back to work is our primary focus.

    Medical Cost Containment/Pharmacy First Fill program

    • Management of the medical expense portion of a claim is critical.  Medical claim costs can escalate quickly, so OneBeacon works with key partners to deploy a full array of cost containment programs.  These programs begin immediately after an injury occurs and will continue as long as treatment is medically necessary.  Our cost containment programs include:
