Okla. Admin. Code § 317:30-3-16
Providers must agree to furnish the medical information necessary for payment of a claim upon request by the Fiscal Agent or OHCA. A release of information for medical records is obtained at the time an application is made for medical assistance. The application specifically states: "For the purpose of determining whether any payment will be made in the behalf of the patient for any medical services, hereafter reported, I do hereby authorize the Authority, or any representative thereof, authorized for the purpose of determining compensability of claims in the patient's behalf, to inspect all hospital and medical records pertaining to such hospitalization or medical services; and I do further authorize the hospital, physician, or other medical provider to release and furnish to the Authority and its representatives, any information shown in such records".
