Medicaid and CHIP Program (MACPro) Portal

The Center for Medicaid and CHIP Services (CMCS) and the Centers for Medicare & Medicaid Services (CMS) regional offices adjudicate more than 2,000 actions annually, including state plan amendments (SPAs), waiver applications, advanced planning documents, and more. CMCS also engages in extensive work in the oversight of current programs and the development of new policy (regulations, state Medicaid director letters, ongoing technical assistance to states, etc.) to keep pace with state and industry innovations.

Medicaid and Children's Health Insurance Program (CHIP) represent a federal and state partnership. As part of Medicaid and CHIP Business Information Solution, CMS has built a new state-facing system to capture states’ submissions of SPAs, waivers, advanced planning documents, etc. This system, the Medicaid and CHIP Program (MACPro) system, has been live as of December 2015 and continues to expand to include new authorities and state actions for CMS review.

CMS is developing the MACPro system, to make the process of modifying state plans, demonstrations, and waivers more streamlined, efficient, and transparent for state partners and researchers.

Explore the currently available systems and documents to apply for a change to state Medicaid plans, waivers, and demonstrations.

One Medicaid and CHIP Program System (OneMAC)


OneMAC allows CMS and states to collaborate online to process Medicaid business, such as SPAs, more efficiently and effectively. Beginning February 1, 2022, paper-based submissions will be processed in OneMAC. SPAs and Waivers currently submitted through existing systems (e.g., MACPro & WMS/MMDL) will remain in those systems. OneMAC supports paper-based Medicaid SPAs, CHIP SPAs, 1915(b) waiver actions, Appendix K 1915(c) waiver amendments, state responses to formal Requests for Additional Information (RAIs) for these SPA and waiver actions, and state temporary extensions to their 1915(b) and (c) waivers. At this time, OneMAC does not support editing of submissions during the review process. States should work with their CMS Point of Contact and review team when there is a need to supply revised submissions or additional submission documents during the review process.

For OneMAC assistance, please email the help desk at OneMAC_HelpDesk@cms.hhs.gov or call 833-228-2540.
