Aetna in Michigan: one application for the commercial network, a different map entirely for behavioral health
Michigan splits behavioral health in a way few states do: specialty BH for Medicaid lives inside a public system of 10 regional PIHPs and roughly 46 county mental health programs, a structure that just survived the state's own attempt to redraw it. Aetna's commercial network sits outside all of that, with its own contract-first process. For a BH group staffing limited-licensed clinicians, the two systems also disagree about whether those clinicians can earn at all.
Common mistake
Aetna's gate comes before credentialing, and BH has its own door
Aetna is contract-first: request participation, wait up to 45 days for a network-need decision, and only then does credentialing begin with a pull from CAQH ProView. Behavioral health professionals use Aetna's dedicated BH request-for-participation form rather than the medical flow, because Aetna Behavioral Health is an internal business unit, not a carve-out vendor. Two failure modes follow directly: a BH application filed through the medical flow, and a CAQH profile that was never authorized to Aetna, which fails without a notice.

Where a limited-licensed clinician earns in Michigan, and where they cannot
Michigan's limited licenses, the LLMSW, LLPC and their MFT and psychology equivalents, are first-class rendering material on the Medicaid side, under same-profession supervision. Aetna's commercial network publishes no equivalent lane. For a group whose staffing model leans on limited licensees, this is the difference between the two panels.
| Michigan Medicaid (PIHP/CMHSP and MHP side) | Aetna commercial | |
|---|---|---|
| Can a limited licensee's work be paid? | Yes, under supervision of a fully licensed provider of the same profession | No published lane, independent licence expected |
| Whose NPI carries the claim today? | Reported under the supervising provider | The credentialed clinician's |
| What changes 2026-08-01 (proposed) | Limited licensees enroll in CHAMPS as Rendering Only and appear under their own NPI, paid to the billing organization | Nothing |
| Direct payment to the limited licensee | Never, reimbursement goes to the associated billing provider | Not applicable |

Hard rule
The 10-PIHP map stands. The state's own page saying otherwise is stale.
Michigan tried to consolidate its 10 specialty-BH regions into 3 through a 2025 procurement. A Court of Claims order found the RFP impermissibly conflicted with Michigan law, and MDHHS withdrew it in February 2026, leaving the existing structure in place: 10 PIHPs holding regional capitation, subcontracting to roughly 46 county CMHSPs across 83 counties. Anyone re-planning Michigan contracting maps around a 3-region model is planning against a procurement that no longer exists. A BH provider reaching Medicaid members still contracts at the CMHSP level, with CHAMPS state enrollment underneath.

How to apply to Aetna from Michigan
The Aetna flow is national. The Michigan-specific work is everything around it.
- 1 Submit the request for participation via Aetna's online RFP. BH clinicians use the dedicated Behavioral Health form.
- 2 Make CAQH ProView complete, attested, and authorized to Aetna before the network decision lands.
- 3 Expect the network-eligibility answer within 45 days, credentialing after, contract last. Document the access gap you fill in the request itself, because the network-need decision is the most common rejection and credentials cannot appeal it.
- 4 If Medicaid members are in the plan at all: enroll in CHAMPS first, always. Providers in plan networks must be screened there too, and skipping it denies claims statewide.
- 5 Specialty-BH Medicaid work routes through the county CMHSP and regional PIHP, a separate application from anything Aetna touches.

Worth knowing
The 2026-08-01 rendering flip is proposed, not final. Check before you rewire claims.
Policy 2554-BH would move limited-licensed clinicians from supervisor-NPI reporting to their own NPI in the rendering field, with mandatory CHAMPS Rendering Only enrollment and payment flowing to the billing organization. As of mid-2026 it is a notice of proposed policy, contingent on federal approval, and it explicitly does not apply to PIHP-side billing. A group that rewires its claim templates on the proposed date without confirming the final bulletin risks a rejection wave in either direction. Verify the final policy before the first August claim goes out.

Counselors cannot compact into Michigan, and that sets the real timeline
Michigan is not a Counseling Compact member, so an out-of-state LPC plans a full LARA endorsement before any Aetna or Medicaid application can start, fingerprints included, since Michigan requires them of every initial health-profession applicant. Physicians fare better on portability, but every relocating clinician should sequence the same way: licence first, then the Aetna request for participation with CAQH ready, then the 45-day network decision, then credentialing. The Michigan-specific costs sit at the front of that chain, which is exactly where a hiring plan can absorb them if it knows they are coming.
