Medical Malpractice Laws in Massachusetts (2026): Deadlines

Massachusetts gives most patients three years to file a medical malpractice claim from the date the claim accrues, with a hard outer deadline of seven years from the negligent act under Massachusetts General Laws Chapter 260, Section 4. Massachusetts also caps noneconomic (pain-and-suffering) damages at $500,000 under Chapter 231, Section 60H, but that cap has broad exceptions and often does not apply to severe injuries. Every malpractice case must also clear a screening tribunal before it can proceed. This guide explains those rules in plain English, but it is general information and not legal advice about your situation.

This page is part of our Medical Malpractice Laws by State series.

What is the deadline to sue for medical malpractice in Massachusetts?

Massachusetts sets a three-year statute of limitations for malpractice claims against physicians, surgeons, dentists, hospitals, and similar providers under Chapter 260, Section 4. The three years run from the date the cause of action accrues, and Massachusetts applies a discovery rule, so the clock generally starts when the patient knew or reasonably should have known of the harm and that it was caused by the provider's conduct. That discovery rule can extend the practical start date, but it does not override the outer deadline described below.

Because accrual depends on what you knew and when, the safest approach is to seek advice as soon as you suspect malpractice and preserve all medical records.

Is there a statute of repose in Massachusetts?

Yes. Chapter 260, Section 4 also contains a seven-year statute of repose, which provides that no malpractice action may be brought more than seven years after the act or omission that caused the injury. Unlike the limitations period, the repose deadline is not extended by the discovery rule, so it can bar a claim even before the patient knows of the harm. The one exception is for a foreign object left in the body, which is not subject to the seven-year repose.

How minors are treated

Massachusetts tolls limitations periods during a plaintiff's minority under Chapter 260, Section 7, but malpractice claims for children have special outer limits. For a minor under the age of six, the action generally must be brought by the child's ninth birthday, and the seven-year statute of repose still applies, again except for a foreign object. Parents and guardians should not assume that minority tolling keeps the deadline open indefinitely.

Does Massachusetts cap medical malpractice damages?

Massachusetts caps noneconomic damages, which cover pain, suffering, loss of companionship, embarrassment, and similar non-financial harms, at $500,000 under Chapter 231, Section 60H. The figure has not been indexed for inflation. Crucially, the cap has broad exceptions: it does not apply if the factfinder determines there is a substantial or permanent loss or impairment of a bodily function, substantial disfigurement, or other special circumstances that would make the limit deprive the plaintiff of just compensation.

Because many serious malpractice injuries meet one of those exceptions, the $500,000 cap tends to bind only in less-catastrophic cases. Economic damages, such as medical bills and lost earnings, are never capped. Separately, under Chapter 231, Section 85K, the tort liability of a charitable or nonprofit organization, including some hospitals, is limited to $100,000 for claims arising from its charitable activities, which is a distinct defendant-specific limit.

Do I need a tribunal or expert review in Massachusetts?

Yes. Every malpractice action against a health care provider must be reviewed by a medical malpractice tribunal under Chapter 231, Section 60B. The tribunal consists of a single justice of the Superior Court, a physician, and an attorney. At the hearing the plaintiff presents an offer of proof, and the tribunal decides whether the evidence, if properly substantiated, raises a legitimate question of liability appropriate for judicial inquiry, or whether the case is merely an unfortunate medical result.

If the tribunal finds against the plaintiff, the case can still proceed, but only if the plaintiff posts a bond. Because the offer of proof must show a departure from the standard of care and resulting harm, expert support is effectively required from the outset of a Massachusetts malpractice case.

Pre-suit notice in Massachusetts

Massachusetts also requires advance notice before suit. Under Chapter 231, Section 60L, a claimant generally must give the health care provider 182 days' written notice of intent to file a malpractice claim before filing the complaint. The notice period can be shortened to 90 days in certain circumstances, and there are limited situations where notice is not required, such as when a provider could not reasonably have been identified before filing.

Who can be held liable, and the standard of care

A Massachusetts malpractice claim can target physicians, hospitals, nurses, and other licensed providers whose care fell below the accepted professional standard. To win, a plaintiff generally must prove what a reasonably competent provider in the same field would have done, that the defendant departed from that standard, and that the departure caused the injury. Expert testimony is normally required to establish the standard of care and causation, which is why the tribunal's offer-of-proof stage is so important.

Comparative negligence in Massachusetts

Massachusetts follows modified comparative negligence under Chapter 231, Section 85. A plaintiff's recovery is reduced in proportion to his or her share of fault, but a plaintiff who is more than 50 percent at fault, meaning the plaintiff's negligence is greater than the combined negligence of the defendants, recovers nothing. This rule can matter where a provider argues the patient contributed to the harm.

Wrongful-death medical malpractice in Massachusetts

When negligent care causes a death, the claim is brought as a wrongful-death action under Chapter 229, Section 2, by the executor or administrator of the estate. That action generally must be commenced within three years of the death, or within three years of when the executor or administrator knew or reasonably should have known of the factual basis for the claim. The same tribunal and notice requirements that apply to malpractice claims generally apply here as well.

How to evaluate a possible claim

If you believe you or a loved one was harmed by medical care in Massachusetts, practical first steps include gathering complete medical records, noting key dates, and consulting an attorney well before the three-year limitations period and seven-year repose deadline close. Most malpractice attorneys offer a free initial consultation and work on a contingency fee, meaning they are paid a percentage of any recovery rather than upfront. No attorney or website can guarantee that a case will succeed or predict a dollar amount, because outcomes depend on the specific facts, the records, the tribunal stage, and expert review. Consulting a licensed Massachusetts attorney early is the safest way to protect your rights.
