The injury lasts a lifetime. The case has to be built to that scale.

Why does lifetime cost decide what a catastrophic case is worth?

Because in a catastrophic case, the bills you have received are the smallest part of the loss. The claim is priced on what the injury will cost for the rest of your life, and that number exists only if someone builds it.

The past medical number is set by statute. Since the 2017 amendment to RSMo 490.715 (effective August 28, 2017), the recoverable figure for treatment already rendered is the actual cost — what was paid plus what is still owed after contractual write-offs — not the hospital’s billed sticker price. Anyone who values your case off the raw billing statements is starting from a number Missouri law does not use.

The future number has no invoice yet. It is built through life-care planning: physicians and rehabilitation specialists project every element of future care — surgeries, attendant hours, equipment replacement cycles, medication, home modification — and an economist reduces the decades of cost, plus lost earning capacity, to a present dollar value that can be defended in a Missouri courtroom. In this region that record is typically assembled while treatment runs through a Level I trauma center and into rehabilitation, and the case should not resolve before the projection is credible. Settle before the life-care plan exists and the missing decades are simply donated to the insurer.

How long do I have to file a catastrophic injury lawsuit in Missouri?

Most Missouri personal injury claims must be filed within five years of the injury (RSMo 516.120, unchanged since 1939). A 2026 bill to shorten this deadline (HB 1645, folded into HCS HBs 1664, 1610, 1645 & 2182) passed the House but died in the Senate — the five-year period is unchanged as of August 2026. Our explainer on whether Missouri’s filing deadline changed covers the bill’s full path.

Two exceptions matter more in catastrophic cases than anywhere else. If the injury proves fatal, the family’s claim becomes a wrongful death case with a three-year deadline, not five. And if the responsible party is a government entity, everything shortens: before suing the City of St. Louis over a defective street, sidewalk, bridge, or thoroughfare, RSMo 82.210 requires written notice to the mayor within 90 days of the injury. Five years of runway does not mean five years to start.

Can a catastrophic injury case include punitive damages?

Rarely, and only through a gate the legislature rebuilt in 2020. Under RSMo 510.261 (effective August 28, 2020), punitive damages require clear and convincing evidence that the defendant intentionally harmed the plaintiff without just cause or acted with a deliberate and flagrant disregard for the safety of others.

The procedure is as strict as the standard. A punitive damages claim cannot appear in the initial petition at all: the court must grant leave to add it later, on a written motion supported by affidavits, exhibits, or discovery materials, filed no later than 120 days before the final pretrial conference or trial date. That is why we treat punitive damages as something the evidence must earn during the case — never as a promise made at intake.

Who gets paid out of the settlement besides you?

Medical lienholders will claim a share — and Missouri caps it. Under RSMo 430.225 (effective August 28, 2006), providers holding liens share at most 50% of the settlement’s net proceeds — what remains after attorney fees and case expenses — and a provider that takes lien payment releases the patient from the rest of that bill.

This matters most to people treated on a lien basis because they were uninsured after a catastrophic injury: the statute is what stops the providers from swallowing the whole recovery. Negotiating those liens down — along with health insurer, Medicare, and Medicaid claims — is part of the representation, not an extra, and it happens before anything is distributed to you.
