Damage caps
For 2026, Missouri's published noneconomic limits are $481,493 for ordinary personal injury and $842,614 for catastrophic injury or death claims under the medical statute. Economic losses are not capped by that noneconomic schedule. The jury is not told about the limit.
Not capped
Economic damages
RSMo 538.210 does not set a general ceiling on economic damages in a medical malpractice case. Economic losses are limited by proof.
Capped
Noneconomic damages
Noneconomic damages for non-catastrophic personal injury are capped and rise 1.7 percent each January 1. The statutory base is $400,000. The Missouri Department of Insurance publishes the indexed figure. For 2026 that published limit is $481,493, irrespective of the number of defendants.
Catastrophic personal injury and death use a higher indexed cap. The statutory base is $700,000. The 2026 published figure is $842,614. Catastrophic injury, defined in RSMo 538.205, includes quadriplegia, paraplegia, loss of two or more limbs, significant permanent cognitive impairment, irreversible major-organ failure, or significant vision loss. Death claims use the higher noneconomic limit. Use the Department of Insurance year table. Do not stop at the stale $400,000 and $700,000 bases. The jury is not told about the limit.
The ordinary 2026 noneconomic limit applies irrespective of the number of defendants. Confirm how a particular verdict is allocated before treating any defendant as having a separate full cap.
Watts v. Lester E. Cox Medical Centers. In 2012, the Missouri Supreme Court held the then-existing noneconomic cap unconstitutional as applied to a common-law personal-injury medical negligence claim, on jury-trial grounds. The General Assembly later replaced that common-law claim with a statutory health-care liability action and reenacted indexed caps. Sanders v. Ahmed (2012) upheld noneconomic limits in the wrongful-death setting. This page does not treat Watts as automatically voiding the current 2015 statutory framework. Counsel should still watch further constitutional challenges.
2026 published noneconomic limits
The figures below are the 2026 indexed amounts published by the Missouri Department of Insurance. They are not payment averages. The statutory bases are lower and are not the current-year limits.
| Milestone | Ordinary injury | Catastrophic or death |

The limits rise 1.7 percent each January 1 under RSMo 538.210. The 2026 row is the Department of Insurance figure for this review. The statutory base row is not the amount to use for a 2026 case. The higher track covers catastrophic injury, as defined in RSMo 538.205, and death. Punitive damages against a covered health care provider require clear and convincing proof of intentional damage or malicious misconduct. Ordinary negligence, including conscious disregard, is not enough under RSMo 538.210.8.
Punitive damages
Punitive awards against covered health care providers require clear and convincing proof of intentional damage or malicious misconduct. Evidence of ordinary negligence, including conscious disregard, is not enough under RSMo 538.210.8.
Filing deadlines
File within two years of the negligent act in most cases, with narrow discovery rules for foreign objects and certain test-result failures, and a ten-year outer limit. File the required affidavit within 90 days, or any court-approved extension.
- General rule
An action for malpractice, negligence, error, or mistake related to health care generally must be brought within two years from the date of the act of neglect complained of.
- Narrow discovery rules
A foreign-object claim is generally two years from discovery, or from when ordinary care should have discovered it. Failure to inform of medical test results has a separate discovery-based two-year rule, with statutory caveats.
- Minors and outer limit
A minor under 18 generally has until the twentieth birthday. In no event may the action be brought more than ten years from the act of neglect, or two years from a minor's eighteenth birthday, whichever is later.
- Service
After filing, service on a defendant generally must occur within 180 days or the action is dismissed. Dismissal is without prejudice unless there was a prior nonsuit.
- Affidavit of merit
The plaintiff or counsel must file an affidavit stating that a written opinion was obtained from a legally qualified health care provider that the defendant failed to use the care of a reasonably prudent provider and that the failure directly caused, or contributed to cause, the claimed damages. A separate affidavit is required for each defendant. It is due within 90 days after filing. The court may extend that time up to another 90 days for good cause. Failure to file leads to dismissal without prejudice on motion.

Two indexed noneconomic tracks
The valuation headline is the split between ordinary personal injury and catastrophic injury or death. Use the Department of Insurance figure for the year, not the statutory base alone.

The affidavit is an early trap
A separate affidavit of merit is due for each defendant within 90 days after filing, unless the court grants a good-cause extension of up to another 90 days. Missing it can end the case without prejudice.
Watts did not erase the current statute
Watts struck an older common-law personal-injury cap. The legislature then enacted a statutory cause of action and indexed caps. Do not describe Missouri as a state with no cap on the strength of Watts alone. Constitutional risk is still a question for counsel.
Payout context
Payment amounts vary by year, injury, and setting. This page does not state an average payout, a median, or a case count. To predict the payout for a Missouri case, use MedMalPredict AI - Medical Malpractice Outcome Prediction.
The ordinary or catastrophic cap track, and whether the affidavit of merit is filed on time, often shape the range. Watts struck an older personal-injury cap. It does not, by itself, erase the current statutory limits.
Sources
Official statute and agency pages checked September 22, 2026. First research pass on September 22, 2026. This summary still needs legal review before it is treated as legal advice. RSMo 538.210 is a post-2015 statutory health-care liability action with dual noneconomic caps that rise 1.7 percent each January 1. The Missouri Department of Insurance publishes 2026 amounts of $481,493 for non-catastrophic personal injury and $842,614 for catastrophic injury or death. Watts (2012) struck a prior personal-injury cap under the older common-law framework. Sanders (2012) upheld wrongful-death noneconomic limits. Watts is not treated here as voiding the current statutory framework, but further constitutional challenges remain a counsel question. An affidavit of merit is due under RSMo 538.225. The limitations period is two years, with a ten-year outer limit, under RSMo 516.105.
