Michigan Is a Restricted Practice State
The American Association of Nurse Practitioners classifies Michigan as restricted practice: state law requires career-long supervision, delegation or team management by another health provider for the NP to provide patient care. 11 of the 50 states and DC have that classification, and they are where NP applications most often stall on agreement paperwork.
For credentialing, restricted practice means the supervising physician is effectively part of your application. Michigan Medicaid and the commercial plans, including Blue Cross Blue Shield of Michigan, typically ask for the supervision or delegation agreement, the physician's name, NPI and license, and sometimes the physician's own attestation. Some plans in restricted states credential NPs only as members of a physician-led group, so an NP-owned entity may be told the panel is limited even when the application is complete.
Medicare enrolls the NP on the CMS-855I without asking for the agreement, but its NP rule (42 CFR 410.75) requires compliance with Michigan law, so supervision has to be in place before you bill WPS Government Health Administrators. When the supervising physician leaves, the NP's ability to practice and to be paid depends on a new agreement being signed and reported to every plan, which makes that change the single biggest credentialing risk for a Michigan NP.

Questions Michigan NPs Ask
Do Michigan nurse practitioners need a collaborating physician to get credentialed?
Yes in practice. AANP classifies Michigan as restricted practice, and Michigan Medicaid and most commercial plans ask for the supervision or delegation agreement and the physician's name and NPI with the application.
How does a Michigan NP join Michigan Medicaid?
Enroll with the Michigan Department of Health and Human Services through CHAMPS, the Community Health Automated Medicaid Processing System. Most Michigan Medicaid members are in managed care (2,362,189 enrolled across 9 plans in 2024), so after the state enrollment is active, each plan you want, such as Meridian Health Plan of Michigan, Molina Healthcare of Michigan, Blue Cross Complete of Michigan, credentials you separately.
Can an NP licensed in Michigan see patients in a neighboring state?
Only with a license from that state, and each state's practice rules apply to the patients there. Indiana is reduced practice; Ohio is reduced practice; Wisconsin is reduced practice. Payer enrollment is also per state, so seeing patients across the line means a separate Medicaid enrollment and separate commercial applications there.
What does PECS charge a Michigan NP?
