Applicants for disability benefits filed pursuant to sections 507-a and 605 are required to identify all hospitalizations and all doctors who have treated the applicant in connection with his or her alleged disability. The determining authority may request that the applicant file a written waiver of confidentiality with respect to medical records relating to such doctors and hospitalizations. Upon receipt of such waiver, the Retirement System shall attempt to obtain all medical records available from each doctor and hospital identified by the applicant, and the determining authority shall review and consider all records so obtained in connection with determining each application.
