Michigan Medicaid

Michigan Medicaid, enrolled and paid

An approved Michigan Medicaid enrollment, revalidations closed inside the window, and payments that reach the right address.

Michigan screens and enrolls every provider who serves its Medicaid members, and a 2026 bulletin requires limited licensed behavioral health clinicians to enroll and appear on claims in their own name. The Michigan Department of Health and Human Services runs Medicaid and explains each step on its Medicaid provider enrollment page.

In the official words

All providers who serve Michigan Medicaid beneficiaries are required to be screened and enrolled

Michigan Department of Health and Human Services

All providers must revalidate their Medicaid enrollment information a minimum of once every five years, or more often if requested by MDHHS.

Michigan now enrolls limited licensed behavioral health clinicians

Bulletin MMP 26 30, issued July 31, 2026 and effective September 1, 2026, requires Master's level Temporary Limited Licensed Psychologists, Limited Licensed Counselors, Educational Limited Licensed Marriage and Family Therapists and Limited Licensed Master's level Social Workers who serve Medicaid members to be enrolled and uniquely identified on claims. Michigan Medicaid bulletin MMP 26 30, July 2026

Each enrolls online as a rendering only provider with an individual NPI, associates to the clinic, group or employer that bills for the work, and reports the NPI of a Medicaid enrolled, fully licensed supervisor of the same profession. These clinicians are not paid directly, and from September 1, 2026 their services are no longer reported under the supervisor's NPI. Michigan Medicaid bulletin MMP 26 30, July 2026

Clinicians already enrolled under a managed care only specialty did not have to reenroll, but the bulletin gave them until November 1, 2026 to add the supervisor's NPI and association or face disenrollment and claim denials. If that date passed without the update, confirm the enrollment status with MDHHS Provider Enrollment now. The bulletin's enrollment and billing steps do not apply to PIHPs and their providers.

How enrollment works, step by step

  1. Register the SSN or EIN with the state's vendor registration, SIGMA Vendor Self Service, before starting the Medicaid application. Individual, group and facility enrollments need it; a rendering only enrollment does not. Michigan MDHHS, register for SIGMA
  2. Enroll the billing entity first. A rendering provider cannot submit a new enrollment until its billing provider is approved, and providers tied to a group wait until the group is approved. Michigan MDHHS, determine the enrollment type
  3. Put an NPI in every provider loop on the claim: billing, rendering, referring, ordering and prescribing. Michigan MDHHS, determine the enrollment type Anyone who orders, prescribes, refers or certifies eligibility for services must be screened and enrolled. Michigan Medicaid Provider Manual, October 2026
  4. Ask for the start date you need on the application. Participation begins on the date the online application is submitted, or can be backdated up to one year from the request when licensure or certification covers that whole period. Michigan Medicaid Provider Manual, October 2026

A rendering clinician waits on the billing provider's approval Michigan MDHHS, determine the enrollment type and a limited licensed clinician also on a supervisor's enrollment Michigan Medicaid bulletin MMP 26 30, July 2026, so the Michigan files we build carry a planning range of 45 to 90 days from submission to an active Medicaid ID.

Revalidation runs on a 90 day clock in Michigan

Every provider revalidates at least once every five years, or more often if MDHHS asks. Michigan Medicaid Provider Manual, October 2026 The provider has 90 days to finish it online. A letter goes to the correspondence address on the enrollment 90 days before the cycle end date and a second one 30 days before if the work is not done. Michigan MDHHS, group revalidation instructions

A revalidation that is not completed by the last day of the period generates a termination letter, and the enrollment is closed. Reopening it takes a call to MDHHS Provider Enrollment. Michigan MDHHS, group revalidation instructions

Institutional providers pay an application and revalidation fee for each enrolled provider type. Individual physicians and non physician practitioners do not, and a provider enrolled with Medicare or another state's Medicaid or CHIP program, or one that already paid the fee there, does not pay the Michigan application fee. Michigan Medicaid Provider Manual, October 2026

Where Michigan enrollments lose money

Since November 1, 2026, a provider whose pay to address produces an undeliverable check is contacted by MDHHS and given 30 days to fix it. Missing that window inactivates the provider's SIGMA vendor account and stops payment, and providers sharing the SIGMA Vendor ID and rendering providers tied to the billing provider are affected too. Michigan MDHHS provider alert, October 13, 2026

The manual is just as strict about mail. The Provider Enrollment Unit disenrolls providers when postal mail comes back nondeliverable, and enrollment changes must be reported within 35 days. Michigan Medicaid Provider Manual, October 2026

MDHHS communicates by the email address in the online enrollment record, and keeping it valid is the provider's job. Michigan MDHHS, Medicaid provider enrollment For limited licensed clinicians, disenrollment of the supervising provider may prompt disenrollment of the supervisee.
