Medical Malpractice Laws in Oregon (2026): Deadlines & Caps

Oregon's medical malpractice rules are shaped as much by its Supreme Court as by its statutes, which is why the damages picture has to be stated carefully. A patient generally has two years from discovery to sue under ORS 12.110(4), with a five-year outer limit, and there is currently no enforceable statutory cap on noneconomic (pain and suffering) damages in a personal-injury malpractice case after the Oregon Supreme Court's ruling in Busch v. McInnis Waste Systems.

This page is general legal information, not legal advice, and it is part of our Medical Malpractice Laws by State series. Deadlines and the cap analysis depend on the facts and on whether the claim is for injury or for wrongful death, so confirm your situation with a licensed Oregon attorney.

What counts as medical malpractice in Oregon?

Medical malpractice in Oregon is a negligence claim arising out of medical, surgical, or dental treatment, where a health care provider failed to meet the standard of care and that failure caused injury. The plaintiff must prove the provider owed a duty, breached the applicable standard of care, and that the breach caused compensable harm. A disappointing outcome is not enough on its own; the care itself must have fallen below what a reasonably careful provider in the same field would have done.

The statute of limitations to sue in Oregon

Under ORS 12.110(4), an action for injuries arising from medical, surgical, or dental treatment, omission, or operation must be commenced within two years from the date the injury is first discovered or, in the exercise of reasonable care, should have been discovered. This discovery rule means the two-year clock can start later than the date of the treatment if a reasonable patient would not yet have known of the injury and its likely connection to the care. The same statute applies whether the claim sounds in tort or in contract.

Oregon's statute of repose

Oregon pairs the two-year discovery rule with a firm outer deadline. ORS 12.110(4) provides that every such action must be commenced within five years from the date of the treatment, omission, or operation on which the action is based. The one statutory escape is fraud, deceit, or misleading representation that prevented timely filing, in which case the action may be brought within two years from when that fraud or concealment was discovered or reasonably should have been discovered. Apart from that, the five-year repose period can bar a claim even if the injury was genuinely undiscoverable.

Damage caps in Oregon: the careful, current picture

This is the point most worth getting right for Oregon, because the answer is different for injury cases and death cases. Oregon's $500,000 cap on noneconomic damages lives in ORS 31.710(1). The Oregon Supreme Court has not struck the statute down in every setting, so a blanket statement that Oregon has no cap, or that it has a $500,000 cap, would both be wrong.

For a personal-injury medical malpractice case, there is currently no enforceable statutory cap on noneconomic damages. In Busch v. McInnis Waste Systems, Inc., 366 Or 628, 468 P.3d 419 (2020), the Oregon Supreme Court held that applying the ORS 31.710(1) cap to a personal-injury plaintiff violated the remedy clause of Article I, section 10, of the Oregon Constitution. That decision built on the analytical framework the court adopted in Horton v. OHSU, 359 Or 168, 376 P.3d 998 (2016). The legislature later amended ORS 31.710 (2021), and the statute as now codified addresses wrongful death rather than general personal injury.

For a wrongful-death medical malpractice case, a $500,000 cap on noneconomic damages still applies under ORS 31.710(1), subject to exceptions. The statute carves out claims under the Oregon Tort Claims Act (ORS 30.260 to 30.300) and workers' compensation matters under ORS chapter 656, and in Vasquez v. Double Press Mfg., Inc., 364 Or 609 (2019), the court held the cap does not apply where the plaintiff has received or will receive workers' compensation benefits for the injury. The cap does not apply to punitive damages, and there is no statutory cap on economic damages such as medical bills and lost income.

Watch out: Older sources sometimes say Oregon has a flat $500,000 noneconomic cap on all malpractice claims. After Busch (2020) and the 2021 amendment, that cap is not enforceable in a personal-injury malpractice case. It currently applies to wrongful-death claims, with the Tort Claims Act and workers' compensation exceptions noted above.

Certificate of merit and pre-suit requirements

Oregon does not require a pre-suit certificate or affidavit of merit, and there is no mandatory pre-suit notice of intent, screening panel, or review board that a private malpractice plaintiff must clear before filing. That is a meaningful difference from states like Pennsylvania or Florida. In practice, however, attorneys still arrange expert review early, because Oregon law requires expert testimony to prove the standard of care and causation in most malpractice cases, and a claim without expert support is unlikely to survive.

Who can be liable and the expert requirement

Oregon malpractice claims can be brought against individual clinicians and the institutions responsible for their care, including physicians, nurses, dentists, and hospitals. A hospital can be liable for its own negligence and, in many situations, for the negligence of its employees. Because the standard of care is a technical question, Oregon generally requires qualified expert testimony to establish what a reasonably careful provider would have done and to connect any breach to the patient's injury.

Comparative negligence in Oregon

Oregon uses modified comparative negligence under ORS 31.600. A plaintiff's damages are reduced in proportion to the plaintiff's own share of fault, but a plaintiff whose fault is greater than the combined fault of the defendants recovers nothing. In practice that means a patient who is found 51 percent or more at fault for the harm cannot recover, while a patient who is 50 percent or less at fault recovers a reduced award.

Wrongful-death medical malpractice in Oregon

When malpractice causes death, the claim proceeds under Oregon's wrongful-death statute, ORS 30.020, brought by the personal representative of the estate for the benefit of the statutory beneficiaries. Wrongful-death claims carry their own three-year filing framework tied to discovery of the death's cause, and, as explained above, the ORS 31.710(1) noneconomic cap applies to these claims with the Tort Claims Act and workers' compensation exceptions. Because the deadline and the cap analysis differ from an injury case, identifying the correct framework early matters.

How to evaluate and preserve a possible claim

While every situation is different and this is general information rather than legal advice, people who suspect malpractice in Oregon often start by gathering complete medical records and noting key dates, because the two-year and five-year clocks under ORS 12.110(4) can be unforgiving. Since Oregon requires expert testimony on the standard of care, an attorney typically arranges medical-expert review early even though no pre-suit affidavit is mandated. Malpractice cases are commonly handled on a contingency-fee basis, and consulting a licensed Oregon attorney promptly helps confirm the deadlines and the correct injury-versus-death framework, though no attorney can promise a particular outcome or dollar amount.
