(a) Except as provided by Subsection (g), a person who is a member of a retirement system participating in the program provided by this chapter may reestablish service credit, including prior service credit if applicable, previously canceled in another retirement system that is participating in the program provided by this chapter if the person:
(1) is not a current member of the system under which the service was performed;
(2) in the case of the Texas County and District Retirement System, does not have an open account with the subdivision for which the person performed the service for which the credit is sought; or
(3) in the case of an employee to whom § 803.204 applies, does not have an open account with the employing hospital district, charitable organization, or administrative agency, as applicable, for which the person performed the service for which the credit is sought.
(b) A person may apply to reestablish service credit under this section by filing an application with the retirement system in which the service was originally credited and a certification that the applicant is currently a member of the certifying system.

(c) Except as provided by Subsection (f), the retirement system in which the service credit was originally credited shall grant the service credit after receiving an application and a certification required by Subsection (b) and:
(1) to reestablish service credit other than in the Texas County and District Retirement System, the Texas Municipal Retirement System, or the retirement system in which a hospital district, charitable organization, or administrative agency described by § 803.204 participates, a contribution in the amount generally required to reestablish service credit in the system, including any applicable interest and membership fees;
(2) to reestablish service credit in the Texas County and District Retirement System, the Texas Municipal Retirement System, or the retirement system in which a hospital district, charitable organization, or administrative agency described by § 803.204 participates, a statement that the applicant does not wish to make a contribution for the service credit; or
(3) at the applicant’s option, to reestablish current service credit in the Texas County and District Retirement System, the actuarial present value of the additional standard service benefits that would be attributable to the credit based on rates and tables recommended by the actuary and adopted by the board of trustees of the system.
(d) A subdivision participating in the Texas County and District Retirement System under Subchapter H, Chapter 844, or a municipality participating in the Texas Municipal Retirement System may make a one-time election to authorize the reestablishment of service credit under this section by payment by an applicant of a contribution in the amount provided by § 843.003 or 853.003, as applicable, for reestablishment of service credit generally in the particular system. If a subdivision or municipality makes an election under this subsection, the applicant has the choice of reestablishing service credit under Subsection (c)(2), (c)(3), if applicable, or this subsection.

Service credit reestablished in the Texas County and District Retirement System or the Texas Municipal Retirement System under Subsection (c)(3) or (d) has the same value as service credit performed for the particular subdivision or municipality at the time of deposit. The credit is creditable to the member’s and employer’s accounts in each subdivision or municipality for which the service was performed.

A person who is a member only of a system that has made an election under § 803.101(f) must pay the actuarial present value, as determined by the appropriate system, of the additional standard service retirement benefits that would be attributable to the service credit to be reestablished in any other public retirement system participating in the program provided by this chapter.
(g) Service credit may not be reestablished under this section:
(1) if it is subject to § 805.002(e); or
(2) in a subdivision participating in the Texas County and District Retirement System or a municipality participating in the Texas Municipal Retirement System if the person who seeks to reestablish the credit is a member only of a retirement system that the subdivision or municipality excludes from participation in the proportionate retirement program under § 803.103.
(h) This section applies to an employee described by § 803.204 on the date the federal government establishes as the effective date of the transfer of federally qualified health center status from a municipality described by § 803.0021(1) to a hospital district, charitable organization, or administrative agency described by § 803.204.
