What the Massachusetts Workers Comp Board Does

The DIA’s main office is at Lafayette City Center in Boston, with regional offices in Fall River, Lawrence, Springfield and Worcester. Coverage is verified through the MAPOC lookup. Administrative judges at the DIA hear disputes; the Reviewing Board hears appeals.

Three things the Massachusetts workers comp board does not do: it does not pay most claims (the employer’s insurer does, unless the state runs the fund), it does not give legal advice, and it does not choose a doctor for you. It is the referee and the record-keeper, which is exactly why its information line is the first free call for a confused claimant.

The Massachusetts Workers Comp Board for Injured Workers

Report the injury to your employer first — that deadline is set by Massachusetts law, not by the agency. Then the Massachusetts workers comp board comes in at three points: filing the worker’s claim form when the employer or insurer will not act, requesting a hearing when a claim is denied or benefits stop, and approving any settlement before it is final.

Bring the claim number, the date of injury, the insurer’s name and every letter you have received. Our Massachusetts claim guide walks through the deadlines and forms before you make the call.

The Massachusetts Workers Comp Board for Employers

Employers meet the Massachusetts workers comp board when they prove coverage, file the first report of injury after an accident, post the required notice in the workplace and — if they qualify — file an exemption. Coverage is bought from a private insurer or the assigned-risk plan; the agency checks that it exists. The threshold and penalties are in our Massachusetts requirements guide.

Massachusetts Workers Comp Board Coverage Lookup, Forms and Poster

Use the agency’s coverage-verification lookup to confirm an employer or contractor is insured: https://www.mapoc.org/. Forms are at the official forms page. The required workplace poster is free from the agency — the companies selling it are selling a free document.

Massachusetts Workers Comp Board Details at a Glance

Before You Call the Massachusetts Workers Comp Board

Agency lines are busiest Monday mornings and the first days of the month. Have the claim number ready, ask for the name of the person you spoke with, and follow up in writing. The Massachusetts workers comp board can explain the process and the deadlines, confirm whether a form was received and tell you how to request a hearing; it cannot tell you what your case is worth.

For that question, our Massachusetts settlement guide and a licensed attorney are the next stops.

District and hearing offices: larger states hear cases at regional offices rather than at headquarters. Where Massachusetts has them, they are listed on the agency site under locations, and the hearing notice names the office for your case.
