If you suffer a work injury in Massachusetts, you have limited time to protect your right to benefits. Missing a deadline could prevent you from recovering compensation.
The four-year statute of limitations
Under MGL c. 152, § 41, you generally have four years to file a formal workers compensation claim with the insurer.
For most injuries, the four-year period begins when you become aware of the connection between your injury or illness and your job. This rule often applies to repetitive stress injuries or exposure-related conditions that develop over time. Key points to understand include:
- Date of awareness: The clock may start when you learn your condition is work-related.
- Occupational illness: You have four years from when you discover the work connection.
- Death claims: A claim must be filed within four years of the worker’s death.
- Appeals: You have four years from receiving a Form 104 denial to file an appeal.
If your injury occurred before Jan. 1, 1986, a one-year deadline may apply.
Workers compensation benefits can cover medical care and a portion of lost wages. If you file late, you may lose access to those benefits entirely.
Reporting your injury right away
Although you have up to four years to file a claim, you should notify your employer as soon as practicable. Delays in reporting can create disputes about whether your injury happened at work. Massachusetts law generally expects:
- Employee notice: Report the injury within seven calendar days.
- Employer report: The employer must notify the insurer and the Department of Industrial Accidents.
Prompt reporting helps preserve evidence and reduce disagreements about fault or timing.
What happens if your claim is denied
If the insurer denies your claim, you may receive a Form 104. You then have four years from the date you received that denial to file a claim with the Department of Industrial Accidents.
Appeal deadlines at later stages can be much shorter. Missing them may limit further review.
Why speaking with an attorney may protect your claim
Workers compensation deadlines can overlap with reporting rules and appeal limits. A mistake at any stage could affect your ability to receive benefits.
An attorney can review your timeline, identify when the statute of limitations began and help you gather the medical evidence needed to support your claim. Legal guidance may also help you respond to a denial or dispute over whether your injury is work-related.
