Does the 2023 Comprehensive Guide to Medicaid Services and Administrative Claiming supersede previous guidance and apply to all entities participating in Medicaid Administrative Claiming (MAC)?

Yes, States are expected to apply the 2023 Comprehensive Guide to Medicaid Services and Administrative Claiming guidance to all MAC programs for all entities. Both previous guidance documents issued by CMS, including the 1997 School-based Services Technical Review Guide and the 2003 School-based Administrative Claiming Guide, are superseded by the 2023 Comprehensive Guide to Medicaid Services and Administrative Claiming.
