The bill amends Section 3009.1 of Title 12 of the Oklahoma Statutes, which pertains to personal injury lawsuits. It introduces several definitions, including "factoring company," "health plan," "health care provider," "letter of protection," and "medical services or treatment." The bill establishes that in civil actions for personal injury, the admissible evidence for damages will be limited to the actual amounts paid for medical services rather than the billed amounts. It also allows for the inclusion of signed statements from medical providers confirming that the amount paid is accepted as full payment. Additionally, it sets forth requirements for disclosing documents related to medical expenses, particularly when treatment is rendered under a letter of protection.

Furthermore, the bill stipulates that damages recoverable for medical services or treatment cannot exceed the amounts actually paid by or on behalf of the plaintiff. It outlines the types of evidence that can be used to establish the reasonable value of past and future medical services, including details about health plan obligations and any agreements made under letters of protection. The bill mandates that plaintiffs disclose specific information regarding their medical expenses and any relationships with health care providers when asserting claims for damages. The provisions of this act will apply to civil actions arising from personal injury filed on or after November 1, 2015, and it is set to take effect on November 1, 2026.
