Missouri Claims Dispute & Statutory Guide
Missouri operates an At-Fault automobile insurance framework under Title XXIV and Title XXXVI of the Missouri Revised Statutes (RSMo). The state enforces pure comparative fault and features a strict common law prohibition against MedPay subrogation. Medical providers utilize optional first-party Medical Payments (MedPay) and enforce statutory hospital liens capped at 50% under RSMo § 430.230.
Statutory Framework & Jurisdiction
At-Fault / Traditional Tort (MedPay Anti-Subrogation & Missouri Hospital Lien Act)
Missouri is a traditional tort jurisdiction applying pure comparative fault (Gustafson v. Benda), permitting an injured party to recover damages diminished by their percentage of fault. Automobile liability coverage is compulsory, while first-party Medical Payments (MedPay) is optional. Missouri courts strictly prohibit insurance companies from subrogating or taking assignments of personal injury claims or first-party MedPay benefits (Benton House, LLC v. Cook & Younts Ins.). Hospitals protect unpaid balances against third-party liability proceeds under the Missouri Hospital Lien Statute (RSMo § 430.230).
PIP / MedPay Coverage & Medical Fee Rules

Under longstanding Missouri public policy and common law (Benton House; Schweiss v. Sisters of Mercy), personal injury claims and first-party medical payments are non-assignable and cannot be subrogated by an automobile insurer against third-party tort proceeds
