OK HB3119

Extends the statute of limitations for health care liability claims (negligence, medical malpractice, lack of informed consent, medical battery) by 1 year after a claimant's good faith belief that federal immunity provisions blocked their lawsuit ceases to exist

Defines "good faith belief" as when a claimant or attorney could reasonably conclude from federal declarations, amendments, advisory opinions, or judicial interpretations that federal liability immunity applied to the alleged conduct

Specifically references the federal PREP Act (Public Readiness and Emergency Preparedness Act, 42 U.S.C. Section 247d-6d) as a qualifying federal procedural bar

Applies to all claims arising on or after February 1, 2020, but does not revive claims already barred by the statute of limitations before the act's effective date

Declared an emergency measure, taking effect immediately upon passage and approval
