Out of State employers are required to cover all their employees, who are working in Massachusetts, with workers' compensation benefits under Massachusetts law. You do not need to buy a policy strictly for Massachusetts if in your existing workers' comp policy Massachusetts coverage is listed in Section 3.A of the policy's Information Page.

If Massachusetts is specifically listed in Section 3.C of the Information Page, the policy is acceptable only if the Insurer (Insurance Carrier) verifies the coverage in Massachusetts. The Insurer must forward a Form 154 verifying workers' compensation coverage in Massachusetts to the Office of Investigations. If the Insurer fails to meet this requirement, a Stop Work Order is immediately issued.

Furthermore, any notation in Section 3.C of the policy's information page that "all states are covered" or "all states are covered except those listed in Item 3.A and the States of: ND OH WA WY" or something similar is acceptable only upon verification of workers' compensation coverage in Massachusetts by the insurer. The insurer must forward a Form 154 verifying workers' compensation coverage in Massachusetts to the Office of Investigations. If the insurer fails to meet this requirement, a Stop Work Order shall be issued immediately.
