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 an ordinarily careful provider in the same or similar circumstances would have done.

For physicians, that duty is codified rather than left to common law alone. ORS 677.095(1) provides that a physician licensed to practice medicine or podiatry by the Oregon Medical Board "has the duty to use that degree of care, skill and diligence that is used by ordinarily careful physicians in the same or similar circumstances in the community of the physician or a similar community." Subsection (2) imposes the same duty on licensed physician associates. Note the locality language: Oregon measures a physician against ordinarily careful physicians in the same or a similar community, not against a purely national benchmark. A separate provision, ORS 677.095(3), adds that in any suit, action, or arbitration seeking damages for professional liability from a health care provider, an issue may not be precluded because of a default, stipulation, agreement, or other outcome in a licensing investigation or administrative proceeding.

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. Even so, our Oregon settlement calculator can turn your own injury and expense figures into a rough range. 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 that the cap does not apply to third-party claims by or on behalf of workers injured in the course of their employment, because such claims are "subject to" provisions of ORS chapter 656. 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 an ordinarily careful provider would have done and to connect any breach to the patient's injury.

The statutory wording matters to that expert question. Because ORS 677.095(1) frames the physician's duty in terms of ordinarily careful physicians in the same or similar circumstances "in the community of the physician or a similar community," an expert is testifying to a same-or-similar-community benchmark rather than to a purely national one, so the expert's familiarity with a comparable practice setting can be contested.

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. ORS 30.020(1) requires the action to be commenced within three years after the injury causing the death of the decedent is discovered or reasonably should have been discovered. That discovery framework does not extend the window indefinitely. The same subsection adds that in no case may an action be commenced later than the earliest of three years after the death of the decedent, or the longest of any other period for commencing an action under a statute of ultimate repose that applies to the act or omission causing the injury, a list that expressly includes the five-year repose in ORS 12.110(4). In a malpractice case, that means the ORS 12.110(4) repose can cut off a wrongful-death claim even where the cause of death was discovered late. 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. With both clocks already running, get a free consultation with an Oregon malpractice lawyer to confirm your deadlines and set up that expert review (attorney advertising).

Frequently Asked Questions

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

Generally two years from when the injury was discovered or reasonably should have been discovered, under ORS 12.110(4), and never more than five years from the treatment, omission, or operation, except where fraud or concealment hid the claim. Tolling can apply for minors and incapacitated persons within limits. Confirm your deadline with an Oregon attorney.

Does Oregon cap medical malpractice damages?

It depends on the type of claim. There is currently no enforceable cap on noneconomic damages in a personal-injury malpractice case, because the Oregon Supreme Court held the ORS 31.710(1) cap unconstitutional as applied to personal injury in Busch v. McInnis Waste Systems (2020). A separate $500,000 noneconomic cap still applies to wrongful-death claims under ORS 31.710(1), with exceptions for Tort Claims Act and workers' compensation cases.

Do I need an expert affidavit to file in Oregon?

No. Oregon does not require a pre-suit certificate or affidavit of merit, and there is no mandatory pre-suit notice or screening panel. However, expert testimony is generally required to prove the standard of care and causation, so attorneys typically arrange expert review before filing anyway.

What standard of care applies to an Oregon physician?

ORS 677.095(1) sets it by statute. A physician licensed by the Oregon Medical Board has the duty to use that degree of care, skill and diligence used by ordinarily careful physicians in the same or similar circumstances in the community of the physician or a similar community. Subsection (2) applies the same duty to licensed physician associates. The community language means the benchmark is a same or similar community rather than a purely national one, which can matter to which experts may testify.

Is the old $500,000 Oregon damages cap still in effect?

Not for personal-injury malpractice claims. The Oregon Supreme Court held the ORS 31.710(1) cap unconstitutional as applied to personal injury in Busch (2020), and the statute was amended in 2021. The $500,000 noneconomic cap currently applies to wrongful-death claims, subject to the Tort Claims Act and workers' compensation exceptions, so the answer depends on whether the case is for injury or death.

What is the statute of repose for malpractice in Oregon?

Five years. Under ORS 12.110(4), a malpractice action generally must be commenced within five years of the treatment, omission, or operation, regardless of when the injury is discovered. The main exception is fraud, deceit, or misleading representation that concealed the claim.

How much is a medical malpractice case worth in Oregon?

There is no set figure. Because there is no noneconomic cap on personal-injury malpractice claims, value depends on the specific evidence of medical costs, lost income, and pain and suffering, and on disputed liability and causation. No attorney can guarantee a result or a dollar amount.

Does fault reduce my recovery in an Oregon malpractice case?

Yes. Oregon uses modified comparative negligence under ORS 31.600. Your damages are reduced by your share of fault, and if your fault is greater than the defendants' combined fault (more than 50 percent), you recover nothing.

What is the deadline for a wrongful-death malpractice claim in Oregon?

Wrongful-death claims proceed under ORS 30.020, brought by the estate's personal representative, and must be commenced within three years after the injury causing the death is discovered or reasonably should have been discovered. There is also a hard outer limit: in no case may the action be commenced later than the earliest of three years after the death, or the longest other period under a statute of ultimate repose that applies, which for malpractice is the five-year period in ORS 12.110(4). The ORS 31.710(1) noneconomic cap also applies to these claims with exceptions. Confirm the framework with an attorney.
