Medicaid Meaningful Use Attestations Now Require a SIGMA Vendor ID

November 06, 2017

On October 1, 2017, the State of Michigan unveiled its new Statewide Integrated Governmental Management Applications (SIGMA) system which is part of Governor Snyder’s vision to improve and streamline functions within state government. SIGMA provides an improved accounting system, a fully integrated procurement system, and a better time, attendance and labor system. SIGMA will replace the legacy MAIN accounting system and affects Meaningful Use attestations done through CHAMPS/eMIPP.

For purposes of the Medicaid EHR Incentive Program, attestations completed after September 9, 2017 will be paid out of the new SIGMA system. Under SIGMA, attestations must include a SIGMA Vendor ID selection by the provider.

On October 2, 2017 all Medicaid EHR Incentive Program attestations that were previously submitted and/or being reviewed but had not yet been approved for payment, were converted to a status of “Correspondence Generated”. Providers need to access their attestations, choose their SIGMA Vendor ID from a drop down list under the eligibility tab, and resubmit their attestation.

If providers are unclear as to what their SIGMA Vendor ID is, they should access the SIGMA Vendor Self Service (VSS) site at, along with either the Existing Vendor user guide if they had an active account in Contract and Payment Express (C&PE) on June 30, 2017 or the New Vendor user guide if they did NOT have an active account with C&PE on June 30, 2017.
