Statutory Framework & Jurisdiction

Applicable Legal System

At-Fault / Traditional Tort (MedPay Anti-Subrogation & Oklahoma Healthcare Lien Acts)

Oklahoma is an at-fault tort liability state that does not mandate Personal Injury Protection (PIP) insurance. Medical expenses incurred from motor vehicle collisions are billed to optional first-party Medical Payments (MedPay) coverage, private health insurance, or third-party automobile liability insurance. Under 36 O.S. § 6092, Oklahoma statute strictly forbids automobile insurers from including subrogation provisions for medical payments in auto policies. Healthcare providers secure treatment balances by filing statutory liens on third-party settlements under Title 42 of the Oklahoma Statutes.
