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. It emphasizes that service providers must not be associated with abortion services and outlines specific criteria for their operation, including annual certification of compliance with the program's life-affirming mission.

Additionally, the bill specifies the types of services that can be provided through the program, such as counseling, care coordination, and educational resources, while explicitly prohibiting the use of program funds for any abortion-related services. It also establishes eligibility criteria for organizations seeking funding, ensuring that they do not have affiliations with abortion services providers. The bill mandates that the Health and Human Services Commission adopt necessary rules to implement these changes, with an effective date set for September 1, 2025.
