3 years: 24 Me. Rev. Stat. Ann. § 2902: actions for professional negligence must be commenced within 3 years after the cause of action accrues. This section does not apply when the cause of action is based upon the leaving of a foreign object in the body, in which case the cause of action accrues when the plaintiff discovers or reasonably should have discovered the harm. For the purposes of this section, the term “foreign object” does not include a chemical compound, prosthetic aid or object intentionally implanted or permitted to remain in the patient’s body as a part of the health care or professional services. If the provision in this section reducing the time allowed for a minor to bring a claim is found to be void or otherwise invalidated by a court of proper jurisdiction, the statute of limitations for professional negligence is 2 years after the cause of action accrues, except that no claim brought under the 3-year statute may be extinguished by the operation of this paragraph.
