What actually differs in Michigan
Credentialing advice written for "most states" tends to be wrong here in specific, expensive ways. These are the rules that only apply in Michigan.
- Behavioral health carve-out structure
-
Michigan carves specialty behavioral health, IDD and SUD out of its Medicaid health plans into the public community-mental-health system: 10 regional Prepaid Inpatient Health Plans (PIHPs) hold the specialty-BH capitation and subcontract to roughly 46 county Community Mental Health Services Programs across all 83 counties. A behavioral health provider typically contracts at the CMHSP level to reach Medicaid members; a solo BH clinician needs CHAMPS enrollment plus the regional PIHP/CMHSP network.

- Medicaid enrollment portal
-
Michigan Medicaid enrollment runs through CHAMPS (Community Health Automated Medicaid Processing System), and every provider serving Medicaid, including those joining Medicaid Health Plan networks, must be screened and enrolled in CHAMPS first, then credential with each MHP. Skipping CHAMPS and assuming MHP credentialing covers you is Michigan's classic claim-denial trap.

- Limited-licensed behavioral health billing MDHHS proposed policy 2554-BH
-
Michigan's limited licenses (LLMSW, LLPC, limited-license MFT, master's TLLP/LLP) are Medicaid rendering material on both sides of the carve-out: on the PIHP/CMHSP side the agency bills while the limited licensee renders under same-profession supervision. On the FFS/health-plan side, services are reported under the supervisor's NPI today, with MDHHS proposed policy 2554-BH set to flip that on August 1, 2026 to the limited licensee's own NPI in the rendering field, via 'Rendering Only' CHAMPS enrollment attached to a billing organization. The policy was still proposed, not final, as of July 2026, re-check before advising on post-8/1 claims.

- PIHP consolidation status (2026) COC 25-000143-MB
-
The proposed consolidation of Michigan's 10 PIHP regions down to 3 is dead: after a January 2026 Court of Claims order found the RFP unlawful, MDHHS withdrew it in February 2026 and the existing 10-PIHP / ~46-CMHSP structure remains in place. No successor procurement has been announced. Do not plan Michigan contracting around a 3-region model.
