(a) In this section, “governing body of a public retirement system” and “public retirement system” have the meanings assigned those terms by § 802.001.
(b) Except as provided by Subsections (c) through (i), the governing body of a public retirement system is subject to this chapter in the same manner as a governmental body.

(c) Records of individual members, annuitants, retirees, beneficiaries, alternate payees, program participants, or persons eligible for benefits from a retirement system under a retirement plan or program administered by the retirement system that are in the custody of the system or in the custody of an administering firm, a carrier, or another governmental agency, including the comptroller, acting in cooperation with or on behalf of the retirement system are confidential and not subject to public disclosure. The retirement system, administering firm, carrier, or governmental agency is not required to accept or comply with a request for a record or information about a record or to seek an opinion from the attorney general because the records are exempt from the provisions of this chapter, except as otherwise provided by this section.
(d) Records may be released to a member, annuitant, retiree, beneficiary, alternate payee, program participant, or person eligible for benefits from the retirement system or to an authorized attorney, family member, or representative acting on behalf of the member, annuitant, retiree, beneficiary, alternate payee, program participant, or person eligible for benefits. The retirement system may release the records to:
(1) an administering firm, carrier, or agent or attorney acting on behalf of the retirement system;
(2) another governmental entity having a legitimate need for the information to perform the purposes of the retirement system; or
(3) a party in response to a subpoena issued under applicable law.
(e) A record released or received by the retirement system under this section may be transmitted electronically, including through the use of an electronic signature or certification in a form acceptable to the retirement system. An unintentional disclosure to, or unauthorized access by, a third party related to the transmission or receipt of information under this section is not a violation by the retirement system of any law, including a law or rule relating to the protection of confidential information.
(f) The records of an individual member, annuitant, retiree, beneficiary, alternate payee, program participant, or person eligible for benefits from the retirement system remain confidential after release to a person as authorized by this section. The records may become part of the public record of an administrative or judicial proceeding related to a contested case, and the member, annuitant, retiree, beneficiary, alternate payee, program participant, or person eligible for benefits waives the confidentiality of the records, including medical records, unless the records are closed to public access by a protective order issued under applicable law.
(g) The retirement system may require a person to provide the person’s social security number as the system considers necessary to ensure the proper administration of all services, benefits, plans, and programs under the retirement system’s administration, oversight, or participation or as otherwise required by state or federal law.
(h) The retirement system has sole discretion in determining whether a record is subject to this section. For purposes of this section, a record includes any identifying information about a person, living or deceased, who is or was a member, annuitant, retiree, beneficiary, alternate payee, program participant, or person eligible for benefits from the retirement system under any retirement plan or program administered by the retirement system.
(i) To the extent of a conflict between this section and any other law with respect to the confidential information held by a public retirement system or other entity described by Subsection (c) concerning an individual member, annuitant, retiree, beneficiary, alternate payee, program participant, or person eligible for benefits from the retirement system, the prevailing provision is the provision that provides the greater substantive and procedural protection for the privacy of information concerning that individual member, annuitant, retiree, beneficiary, alternate payee, program participant, or person eligible for benefits.
