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

Medical malpractice in Wyoming is a claim that a doctor, hospital, nurse, or other licensed health care provider departed from the accepted standard of care and harmed a patient. Wyoming has no cap on malpractice damages against private providers because the state constitution bars damage caps, although a claim against a governmental entity for a provider it employs is limited to $1,000,000 under the Wyoming Governmental Claims Act, and a major procedural step changed when the state repealed its medical review panel in 2022. This page explains the current deadlines, the no-cap status, and the pre-suit landscape under Wyoming law. It is general legal information, not legal advice for your situation.

Statute of Limitations in Wyoming

Under Wyo. Stat. 1-3-107, a claim arising from an act, error, or omission in rendering professional or health care services must generally be brought within two years of the act, error, or omission. A claimant may instead file within two years after discovery if the claimant can establish that the act, error, or omission was not reasonably discoverable within the original two-year period despite due diligence.

The statute also provides a short extension. Under Wyo. Stat. 1-3-107(a)(iv), if the malpractice is discovered during the second year of the original two-year period, the time to file is extended by six months. With discovery turning on the facts, ask a Wyoming malpractice lawyer in a free consultation to work out your filing deadline (attorney advertising).

No General Statute of Repose

Wyoming's current medical malpractice limitations statute does not contain a separate statute of repose or a fixed absolute outer deadline beyond the two-year period and the discovery rule. Latent injuries, including a foreign object left in the body, are handled through the general discovery rule rather than a distinct foreign-object statute.

This means the main timing questions in a Wyoming case turn on when the claim accrued and whether the discovery rule applies, rather than on a separate repose cutoff. The absence of a stated outer ceiling makes the accrual date especially important.

Deadlines for Minors

Wyoming's statute once set a special, shortened limitations rule for minors, but the Wyoming Supreme Court held that provision unconstitutional. In Kordus v. Montes, 2014 WY 146, 337 P.3d 1138, the court held that the minor limitations provision in Wyo. Stat. 1-3-107(a)(ii), and the related health-care carve-out, violated the open-courts guarantee in Article 1, Section 8 of the Wyoming Constitution.

Because the special minor rule was struck down, claims by injured children fall back under Wyoming's general tolling principles for minors. The exact deadline for a child's claim should be confirmed with counsel, since it differs from the adult two-year rule.

Damage Caps in Wyoming: None

Wyoming has no cap on medical malpractice damages, and it cannot enact one without amending its constitution. Article 10, Section 4(a) of the Wyoming Constitution states that no law shall be enacted limiting the amount of damages to be recovered for causing the injury or death of any person.

This constitutional bar applies to economic damages, noneconomic damages such as pain and suffering, and wrongful-death damages. Juries in Wyoming may award damages against a private provider without a legislative ceiling, which makes Wyoming one of the states where no cap applies. Because no legislative ceiling applies to a private provider, plugging your own numbers into our Wyoming settlement calculator still gives a rough range.

One important limit sits outside that rule. When the defendant is a governmental entity sued for the malpractice of a physician, physician assistant, nurse, optometrist, or dentist it employs, Wyo. Stat. 1-39-110(b) provides that the entity's liability shall not exceed $1,000,000 to any claimant for any number of claims arising out of a single transaction or occurrence, nor exceed $1,000,000 for all claims of all claimants arising out of a single transaction or occurrence. That limit reaches county and state hospitals, providers serving state institutions and county jails, and contract providers deemed public employees under Wyo. Stat. 35-31-101 through 35-31-103.

The Medical Review Panel Was Repealed

For years, Wyoming required a claim to go through a medical review panel before suit could be filed, under statutes including the former Wyo. Stat. 9-2-1518. That requirement no longer exists. The Wyoming Legislature repealed the medical review panel act through 2021 House Bill 195, enacted as Chapter 99 of the 2021 session laws, effective July 1, 2022.

As a result, a patient today files a medical malpractice action directly in district court without a mandatory pre-suit panel review. The panel continued only to finish claims that had already been filed with it before the repeal took effect, and it does not screen new cases. The Wyoming Constitution still permits the Legislature to create a panel in the future under Article 10, Section 4(b), but none is currently in force.

No Certificate of Merit or Pre-Suit Screening

Wyoming does not require a certificate or affidavit of merit before filing a medical malpractice case. With the medical review panel repealed, there is currently no statutory pre-suit screening step for malpractice claims at all.

This does not lower the proof burden at trial. A plaintiff still must prove the case with admissible evidence, which in most malpractice cases means qualified expert testimony, even though no expert paperwork is required before filing.

Standard of Care, Liable Parties, and Expert Testimony

Wyoming sets the standard of care by statute. Under Wyo. Stat. 1-12-601(a), a plaintiff alleging negligence by a health care provider must prove that a defendant certified by a national certificating board or association failed to act in accordance with the standard of care adhered to by that national board or association, or, if the defendant is not so certified, that the defendant failed to act in accordance with the standard of care adhered to by health care providers in good standing performing similar health care services. Under subsection (b), variations in theory of medical practice or localized circumstances regarding the availability of equipment, facilities, or supplies may be shown to contravene proof offered on the applicable standard of care. The plaintiff must also prove that the failure caused the injury.

Physicians, hospitals and medical facilities, nurses, and other licensed or certified health care providers can be defendants, and a facility may be liable for the conduct of its employees.

Because these questions turn on medical judgment, expert testimony is generally required to establish both the standard of care and causation. The narrow exception is a case so obvious that a layperson could recognize the negligence. Claims against government-employed providers or public facilities are handled under the Wyoming Governmental Claims Act (Wyo. Stat. 1-39-109 and 1-39-110), which has its own notice and procedural rules and, under Wyo. Stat. 1-39-110(b), limits the governmental entity's liability to $1,000,000 to any claimant and $1,000,000 for all claimants arising out of a single occurrence.

Comparative Negligence in Wyoming

Wyoming follows modified comparative negligence under Wyo. Stat. 1-1-109. A patient who is partly at fault can still recover, but the award is reduced by the patient's percentage of fault, and a patient whose fault is more than 50% of the total fault recovers nothing.

In practice, a patient who is 50% or less at fault can recover a reduced amount, while a patient who is 51% or more at fault is barred. A defense argument that the patient ignored medical instructions or delayed follow-up care can reduce or eliminate recovery.

Wrongful-Death Medical Malpractice

When alleged malpractice causes death, a claim may be brought under Wyoming's wrongful-death statutes, Wyo. Stat. 1-38-101 to 1-38-103. Under Wyo. Stat. 1-38-102, the action is brought by the decedent's wrongful-death representative for the benefit of the statutory beneficiaries, and it must be commenced within two years after the death.

This two-year wrongful-death deadline runs from the date of death and can differ from the timeline in an injury case. Because no constitutional damage cap applies, wrongful-death damages are not subject to a statutory ceiling either, unless the defendant is a governmental entity, in which case the $1,000,000 limit in Wyo. Stat. 1-39-110(b) applies.

How to Evaluate and Preserve a Possible Claim

If you suspect malpractice in Wyoming, request and preserve complete medical records promptly and write down the timeline of events, because those dates drive the deadline analysis. The two-year limit and the discovery rule are strict, and pinning down the accrual date matters because there is no separate repose period to fall back on.

Most Wyoming medical malpractice attorneys offer a free initial consultation and work on a contingency-fee basis, meaning a fee is owed only if the case recovers money. No attorney can guarantee an outcome or a dollar amount; the value of any case depends on the specific facts, the evidence, and how a court applies the law. Consult a licensed Wyoming attorney to evaluate the specific facts and deadlines in your situation.

Frequently Asked Questions

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

Generally two years from the act, error, or omission under Wyo. Stat. 1-3-107, or two years from discovery if the claim was not reasonably discoverable despite due diligence. A six-month extension applies if the malpractice is discovered during the second year of the original window. Deadlines are fact-specific, so consult a licensed Wyoming attorney quickly.

Does Wyoming cap medical malpractice damages?

Not for claims against private providers. The Wyoming Constitution, Article 10, Section 4(a), bars any law limiting the amount of damages recoverable for injury or death, so economic, noneconomic, and wrongful-death damages are not capped. There is one exception: when a governmental entity is sued for the malpractice of a physician, physician assistant, nurse, optometrist, or dentist it employs, Wyo. Stat. 1-39-110(b) limits that entity's liability to $1,000,000 to any claimant and $1,000,000 for all claimants arising out of a single occurrence.

What standard of care must a Wyoming plaintiff prove?

Wyo. Stat. 1-12-601 sets it. If the defendant is certified by a national certificating board or association, the plaintiff must prove the defendant failed to act in accordance with that national board's standard of care. If the defendant is not so certified, the plaintiff must prove a failure to act in accordance with the standard of care adhered to by health care providers in good standing performing similar health care services. Variations in theory of practice and the local availability of equipment, facilities, or supplies may be shown to contravene that proof.

Do I need an expert affidavit or medical review panel in Wyoming?

No. Wyoming does not require a certificate or affidavit of merit, and the former medical review panel was repealed effective July 1, 2022 (2021 HB 195). There is currently no mandatory pre-suit screening step, although expert testimony is generally needed at trial.

Is a medical review panel still required in Wyoming?

No. The Wyoming medical review panel act, including the former Wyo. Stat. 9-2-1518, was repealed effective July 1, 2022. A patient now files directly in district court. The constitution still permits the Legislature to create a panel in the future, but none is in force.

Does Wyoming have a statute of repose for medical malpractice?

No. Wyoming's current malpractice limitations statute does not include a separate statute of repose or a fixed absolute outer deadline. Timing turns on the two-year period and the discovery rule, so the accrual date is especially important.

How does comparative fault affect a Wyoming case?

Wyoming uses modified comparative negligence under Wyo. Stat. 1-1-109. Your recovery is reduced by your share of fault, and if you are more than 50% at fault you recover nothing.

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

Under Wyo. Stat. 1-38-102, the wrongful-death representative must commence the action within two years after the death. That deadline runs from the date of death and can differ from the timeline in an injury case.

How much is a Wyoming medical malpractice case worth?

There is no set figure, and no one can promise a value. Because Wyoming has no damage cap for claims against private providers, recovery depends on the specific economic losses, noneconomic harm, evidence, and comparative fault. If the defendant is a governmental entity, Wyo. Stat. 1-39-110(b) limits its liability to $1,000,000 per claimant and $1,000,000 for all claimants arising out of a single occurrence. A licensed Wyoming attorney can assess the facts after reviewing the records.
