Missouri Medical Malpractice Settlement Calculator
Estimate a medical malpractice settlement under Missouri law. The calculator applies this jurisdiction's own comparative fault rule and damages ceilings, and every figure below is the one our verified data holds, with the statute behind it and the date we checked it.
What Missouri law does to your claim
Four things in state law shape a malpractice claim: how long you have to file, what must happen before you file, what happens if you were partly at fault, and whether the state puts a ceiling on what a jury can award. Here is what we hold for this one.
Missouri uses pure comparative fault.

An affidavit filed with the court stating that the plaintiff has a legally qualified health care provider's written opinion that the defendant failed to use reasonable care and that this caused or contributed to the damages claimed. Mo. Rev. Stat. § 538.225.1 reads: “In any action against a health care provider for damages for personal injury or death on account of the rendering of or failure to render health care services, the plaintiff or the plaintiff's attorney shall file an affidavit with the court stating that he or she has obtained the written opinion of a legally qualified health care provider which states that the defendant health care provider failed to use such care as a reasonably prudent and careful health care provider would have under similar circumstances and that such failure to use such reasonable care directly caused or directly contributed to cause the damages claimed in the petition.” We read this section only, so it is not a complete list of what Missouri requires before a suit. Read from the Internet Archive's capture of the official page as it stood on 2026-06-10; an amendment after that date would not show in it.

None on record means our verified data holds no figure of this kind for this state. It is not a finding that no limit could apply to your claim.
What partial fault costs you in Missouri
The same claim, fracture with surgery, several months of recovery, run through the calculator above four times, with nothing changed but the share of fault assigned to the claimant. The numbers are the engine's output, not an editorial claim about what these cases are worth.
One case, run through the calculator above four times with only the claimant's share of fault changed, under Missouri law. No coverage ceiling is applied, because we would be inventing the at-fault party's policy. These shares illustrate the rule; they are not an estimate of your own fault.
Every Missouri deadline we hold
A claim can be more than one kind of case, and the clock is different for each. These are the Missouri periods in our verified data, with the statute behind each one. A deadline is the outside limit, never a target, and other rules can shorten it.

Every count below is read from our state-law data across all 51 jurisdictions, so it moves when the data does. What you will not find here is an average settlement figure: the only one we could compute is a model, and a model presented as a measurement is not a fact.
- 11 of the 51 jurisdictions we track apply the pure comparative negligence rule, and Missouri is one of them.
- Its 2 years to file is the same as the most common deadline in the country, which 31 jurisdictions use. Across the 51 jurisdictions the deadline for this case type runs from 1 year to 4 years.
- We have read the official text of 26 jurisdictions' rules on what must come before a malpractice suit, and 25 of them require something: a notice to the provider, an expert's affidavit, certificate or opinion, or a review panel. Missouri is one of them.
- 23 of the 51 jurisdictions limit medical malpractice non-economic damages in our data, and Missouri is one of them at $481,493, so a large non-economic award can be reduced to it.
Comparisons are drawn from the legal levers that actually move a case value, not from closed-case data, which we do not hold. See the full methodology
