MAC Mental Health/Individuals with an Intellectual and Developmental Disability (MH/IDD)
Texas has operated the Medicaid Administrative Claiming (MAC) project since 1995. MAC is the cost-based reimbursement methodology Texas uses to draw down federal matching funds for activities that facilitate client access to medically necessary Medicaid-funded services. The Texas Health and Human Services Commission (HHSC) has partners with local Mental Health/Individuals with an Intellectual and Developmental Disability authorities throughout Texas to implement MAC program for providers of MH/IDD services. The purpose of this partnership is to assist HHSC in providing effective and timely access to care for Medicaid recipients, more appropriate utilization of Medicaid covered services, and to promote activities that reduce the risk of poor health outcomes for the state's most vulnerable populations.
All MAC expenditures subject to reimbursement are Title XIX funds. The MAC reimbursements payments received from Medicaid Administrative Claims CFDA #93.778 are subject to the Single Audit Act. Therefore, the funds should be included on the SEFA (Statement of Expenditures of Federal Awards) on each entity's audited financial statements. If the MAC award is identified as a major federal program, the entity's external auditor should perform work deemed necessary to reduce risk and report the funds appropriately in accordance with the Annual Single Audit. The auditor should research all other requirements to ensure that MAC funds are appropriately audited and reported.

The purpose of the Medicaid Administrative Claiming (MAC) program is to provide State affiliated public agencies in Texas the opportunity to submit reimbursement claims for administrative activities that support the Medicaid program. To participate in the MAC program, the MH/IDD provider must be a public entity and enter into a MAC contract with the Texas Health & Human Services Commission (HHSC).
In addition to the contracting process, each MH/IDD provider must also have an active Texas Provider Identifier (TPI) and/or National Provider Identifier (NPI), meet HHSC training requirements and participate in the Random Moment Time Study (RMTS), which includes the certification of the participant list and participation in the time study.
