Senate Bill No. 423 amends existing laws regarding access to medical records in Oklahoma. The bill updates the terminology from "doctor, hospital or other medical institution" to "health care provider or health care facility" and expands the definition of who can request medical records to include personal representatives of patients. It introduces a new provision that requires a court order or written release from an executor or responsible family member for the disclosure of medical records of deceased patients. Additionally, the bill allows health care providers to impose reasonable, cost-based fees for copies of medical records, with specific fee limits established for different types of requests, including those from attorneys and insurance companies.

The bill also modifies the fees associated with obtaining medical records, increasing the base fee for requests from third parties from $20 to $23, and adjusting per-page charges for paper and electronic copies. It clarifies that psychological, psychiatric, mental health, and substance abuse treatment records are subject to different access rules, and it specifies that the provisions do not apply to records of inmates in correctional institutions if their release poses a security threat. The act is set to take effect on November 1, 2025.
