Senate Bill No. 423 amends Section 19 of Title 76 of the Oklahoma Statutes, which governs access to medical records. The bill broadens the definition of who qualifies as a patient to include not only individuals but also their personal representatives, and it specifies that access to medical records for deceased patients requires a court order or written release from an appointed representative or responsible family member. Additionally, the bill introduces provisions for health care providers to impose reasonable, cost-based fees for copies of medical records, while also increasing the base fee charged to third parties for record requests from $20 to $23. The bill also modifies the maximum charge for electronically stored records from $200 to $270.

Furthermore, the bill clarifies that certain types of records, such as psychological and mental health records, are subject to different access rules, and it establishes that individuals involved in personal injury claims waive certain privileges regarding their medical communications. The act is set to take effect on November 1, 2025.
