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)
The One Medicaid and CHIP Program System (OneMAC) system allows CMS and states to collaborate online to process Medicaid business, such as SPAs and waivers, more efficiently and effectively. OneMAC supports the submission of all Medicaid and CHIP SPAs (except SPAs submitted in MACPro), 1915(b) waiver actions, Appendix K 1915(c) waiver amendments, state responses to Requests for Additional Information (RAIs) for these SPA and waiver actions, and state temporary extensions to their 1915(b) and (c) waivers. SPAs and waivers currently submitted through MACPro & WMS will remain in those systems.
Starting July 28, 2025, OneMAC now accepts new submissions of the following types of SPAs:
- Medicaid Alternative Benefit Plan (ABP)
- Medicaid Premiums & Cost Sharing
- CHIP Eligibility
The Medicaid Model Data Lab (MMDL) no longer accepts new submissions for these SPAs. Pending SPAs submitted in MMDL before July 28, 2025, including those on RAI status, will continue to be processed through MMDL.
For OneMAC assistance, please email the help desk at OneMAC_HelpDesk@cms.hhs.govor call 833-228-2540.
