All medical malpractice cases in Massachusetts have a statute of limitations of three years. But, sometimes the malpractice is hard or impossible to detect. Therefore, in such cases, the statute of limitations begins, or accrues when the victim learns or reasonably should have learned of the malpractice. But, no Massachusetts medical malpractice case can begin more than seven years from the date of the actual malpractice. The exception to this rule is when a foreign object is left inside the victim’s body.
