HB 2129 addresses school-based health services and the Medicaid reimbursement process for services provided to public school students. It allows school districts to contract with local mental health authorities to provide mental and behavioral health services on school campuses. It mandates written consent from parents or guardians for such services and requires that a summary of the services be shared with them and, upon consent, with the student’s primary care physician. Additionally, the bill enhances the oversight of the School Health and Related Services (SHARS) program by requiring risk assessments, audits, compliance measures, and the development of training materials. It also allows the Texas Health and Human Services Commission to retain a portion of federal funding for administrative costs. The bill includes provisions to ensure Medicaid reimbursement for mental and behavioral health services provided to eligible students, regardless of their individual education program status.
