A licensee shall not refuse for any reason to make the information contained in the medical records available upon valid request by authorized requesting party to another licensee presently treating the patient. The licensee has a right to request a written release from the patient or legal representative of the patient, authorizing the transfer prior to transfer of said documents. Upon receipt of the written release and authorization, the licensee must tender a copy of said documents to the other licensee within a reasonable period of time. Transfer of said documents shall not be withheld because of an unpaid bill for medical services, but the licensee is entitled to reasonable compensation paid in advance for any copy expenses as provided in Part 2635, Rule 10.6.
