S.B. No. 1388 amends the Health and Safety Code to enhance family support services under the Thriving Texas Families Program, which is a continuation of the alternatives to abortion program. The bill introduces new definitions, including "abortion services provider," "affiliate," "governmental entity," "network contractor," and "program," which clarify the roles and relationships of various entities involved in providing support services. The bill emphasizes that service providers must not be associated with abortion services and outlines specific criteria for their eligibility, including the requirement to certify annually that they uphold the program's life-affirming mission.

Additionally, the bill expands the types of services offered through the program, including community outreach, care coordination, and various forms of support for women facing unexpected pregnancies. It prohibits the use of program funds for any abortion-related services and establishes measures to facilitate participation by smaller service providers with annual revenues under $2 million. The bill mandates that the executive commissioner of the Health and Human Services Commission adopt necessary rules to implement these changes, with an effective date set for September 1, 2025.
