Wyoming Claims Dispute & Statutory Guide
Wyoming operates an At-Fault automobile insurance framework under Title 26 and Title 31 of the Wyoming Statutes. Motor vehicle liability is governed by modified comparative fault with a 51% bar under Wyo. Stat. § 1-1-109. Medical providers bill optional first-party Medical Payments (MedPay) and enforce statutory hospital liens on third-party settlements under Wyo. Stat. § 29-8-101.
Statutory Framework & Jurisdiction
At-Fault / Traditional Tort (Modified Comparative Fault & Wyoming Hospital Lien Act)
Wyoming is an at-fault tort liability state that does not mandate Personal Injury Protection (PIP) insurance. Medical costs resulting from motor vehicle collisions are funded through optional first-party Medical Payments (MedPay) coverage, private health insurance, or third-party automobile liability insurance. Under Wyo. Stat. § 1-1-109, an injured claimant may recover damages if their contributory fault is not more than 50%. Licensed hospitals secure unpaid inpatient and outpatient medical balances by filing statutory hospital liens with the county clerk pursuant to Wyoming Statutes Title 29, Chapter 8.
PIP / MedPay Coverage & Medical Fee Rules
optional Med Pay Coverage
MedPay is optional in Wyoming (commonly written in limits of $1,000 to $10,000+ per person), providing no-fault reimbursement for reasonable medical, surgical, dental, hospital, and ambulance expenses resulting from an automobile collision
made Whole Doctrine
Under Wyoming equitable principles, an automobile insurer's right of subrogation for MedPay benefits is subject to the Made-Whole doctrine, preventing recovery from a third-party settlement until the insured's total losses are compensated
