(a) Medicaid is considered the payor of last resort for a person's medical expenses. As a condition of eligibility, in accordance with 42 CFR §§433.138 - 433.148, an applicant or recipient must:(1) assign to the Texas Health and Human Services Commission (HHSC) the applicant's or recipient's right to recover any third-party resources available for payment of medical expenses covered under the Texas State Plan for Medical Assistance; and(2) report to HHSC any third-party resource within 60 days after learning about the third-party resource.(b) If HHSC determines that a person's employer-based health insurance is cost-effective, the person must participate in HHSC's Health Insurance Premium Payment program as a condition of eligibility. HHSC denies eligibility to a person who voluntarily drops his or her employer-based health insurance or fails to provide HHSC with the information needed to determine cost effectiveness.
