Relating to the eligibility for and provision of benefits under Medicaid or the child health plan program for certain individuals committed, placed, or detained in certain facilities and settings.

HB 4121 requires Texas health officials to assess Medicaid and child health program eligibility for youth in juvenile facilities or foster care before their release. If eligible, they must be enrolled immediately and receive services like telehealth mental health care. The bill mandates that juvenile justice departments create release plans to ensure continuous health coverage after leaving custody, or document barriers if plans cannot be made. This applies specifically to youth under Title 3 of the Family Code, which governs juvenile justice and foster care placements.
