About This Calculator
This calculator finds your exact filing deadline for a medical malpractice claim in Massachusetts. It applies Massachusetts's specific statute of limitations period, checks whether the discovery rule extends your deadline, accounts for tolling if the injured party was a minor, and flags any special notice requirements if your claim involves a government entity. Enter your incident date — or discovery date if the harm wasn't immediately apparent — and the calculator counts forward using Massachusetts's exact rule to show your filing deadline, the time remaining, and an urgency status. Results are based on verified state statute citations, not general estimates.

- Statutory Period: 2 years (730 days)
- Discovery Date (if delayed discovery applies): September 1, 2024
- Standard Filing Deadline: June 1, 2026 (2 years from incident)
- Discovery-Extended Deadline: September 1, 2026 (2 years from discovery)
How Massachusetts's Medical Malpractice Deadline Works
Under Massachusetts Rev. Stat. § 68, Massachusetts provides 3 years to file a medical malpractice lawsuit. The clock typically begins when the injury was discovered — or when it reasonably should have been discovered — rather than on the date the harm occurred. This is known as the discovery rule. Massachusetts extends the filing window by up to 1 additional year under the discovery rule.
Massachusetts's medical malpractice statute of limitations is governed by the state's civil procedure and limitations statutes. Claims against government-owned hospitals or healthcare facilities in Massachusetts are subject to the applicable government tort claims act in addition to the standard medical malpractice procedural requirements. Under state law, the limitations period is tolled for minor claimants until they reach the age of majority at 18.
Special Circumstances
Government entity claims: If the defendant is a government entity, Massachusetts requires a formal administrative claim notice to be filed within 6 months of the incident before a lawsuit may be filed. Missing this notice deadline permanently bars the claim. After the claim is rejected, you have 12 months to file suit.
Minor claimants: If the injured person was a minor at the time of the incident, Massachusetts tolls the statute of limitations until they reach age 18.
Absolute repose period: Massachusetts imposes an absolute repose period of 7 years from the date of the alleged malpractice, regardless of when the injury was discovered.
What Happens If You Miss the Deadline
If a lawsuit is filed after the statute of limitations expires, the defendant can ask the court to dismiss the case as time-barred — and courts almost always grant this motion, regardless of how strong the underlying claim is. The right to sue is lost permanently; there is no general exception for not knowing the deadline existed. A small number of circumstances can pause or extend the clock, covered in the Special Circumstances section above if they apply to your claim type and state. If your deadline is approaching or may have already passed, contact a licensed attorney immediately — some exceptions are themselves time-sensitive.
Frequently Asked Questions
How does Massachusetts determine the clock trigger for medical malpractice?
Massachusetts applies the discovery rule to medical malpractice claims, triggering the statute of limitations when the plaintiff learns, or reasonably should have learned, that they were harmed by the defendant's conduct. This standard protects patients from losing their right to sue before they even realize a clinical error occurred. Prompt investigation is mandatory once a patient suspects their medical care was deficient.
What is the medical malpractice statute of repose in Massachusetts?
Massachusetts imposes a strict seven-year statute of repose that acts as an absolute ultimate deadline for medical malpractice claims. This repose period runs directly from the date of the negligent act or omission and permanently bars the lawsuit once it expires, regardless of the discovery rule. The only significant exception to this harsh cutoff is for foreign objects left in the body.
How does minor tolling apply to medical malpractice in Massachusetts?
Massachusetts law specifically removes the standard minor tolling protections for medical malpractice claims involving young children. A child injured by clinical negligence must have a lawsuit filed on their behalf within the standard timeframe, though the absolute statute of repose may provide a slight extension for infants. Relying on minority to pause the clock will result in the claim being irrevocably barred.
Does Massachusetts require a pre-litigation tribunal for medical malpractice?
Massachusetts law mandates that every medical malpractice lawsuit be screened by a medical malpractice tribunal shortly after the defendant answers the complaint. The plaintiff must present an offer of proof to show there is a legitimate question of liability appropriate for judicial inquiry. If the tribunal finds for the defendant, the plaintiff must post a significant cash bond to continue the litigation.
How are foreign object cases handled under Massachusetts malpractice law?
Massachusetts explicitly exempts cases involving a retained foreign object, such as a surgical sponge, from its strict seven-year statute of repose. For these specific errors, the statute of limitations relies entirely on the discovery rule, allowing patients to sue when the object is finally found. This ensures accountability for blatant surgical mistakes regardless of how much time has passed.
