(a) This chapter governs the eligibility requirements for Medicaid Buy-In for Children (MBIC), which is authorized under Texas Government Code §532.0353. MBIC provides Medicaid benefits under the option explained in §1902(cc) of the Social Security Act (42 U.S.C. §1396a(cc)). (b) MBIC is a Medicaid buy-in program for children with disabilities administered by the Texas Health and Human Services Commission (HHSC). It provides Medicaid benefits to eligible children with disabilities who are not eligible for Supplemental Security Income (SSI) for reasons other than disability. A child does not have to have applied for SSI in order to meet eligibility requirements for MBIC. (c) Nothing in these rules shall be construed to violate the maintenance of eligibility requirements of section 5001 of the American Recovery and Reinvestment Act of 2009 (Public Law 111-5) and make eligibility standards, methodologies, or procedures under the Texas State Plan for Medical Assistance (or any waiver under section 1115 of the Social Security Act (42 U.S.C. §1315)) more restrictive than the eligibility standards, methodologies, or procedures, respectively, under such plan (or waiver) that were in effect on July 1, 2008.
