Michigan Medicaid Credentialing for Therapists

Last updated: July 6, 2026.

If you have tried to get a therapy practice set up with Michigan Medicaid and come away confused, you are not doing anything wrong. Michigan is not a single "sign up and start billing" system. It is a stack of connected-but-separate layers, and the biggest mistake providers make is assuming that finishing one layer means they are done.

Bottom line: In Michigan, getting paid by Medicaid usually takes more than one step. You sign in through MiLogin, enroll as a provider in CHAMPS (the state's Medicaid system), and then, for most of your caseload, you also credential and contract with the Medicaid Health Plan (MHP) the client is enrolled in. Higher-acuity behavioral health is often carved out to a regional PIHP and its local CMHSP instead. CHAMPS enrollment is the required foundation, but it does not automatically make you in-network with every plan. Think of it as five workflows — MiLogin access → CHAMPS enrollment → MHP credentialing → PIHP/CMHSP routing → claims — not one.

This guide gives you the mental model; the rest of our Michigan Medicaid series digs into each piece — enrollment, eligibility checks, prior authorization, telehealth, and denials.

Is there a Michigan Medicaid portal like PAVE or IMPACT?

Yes. CHAMPS is Michigan's equivalent of California's PAVE or Illinois's IMPACT. It stands for the Community Health Automated Medicaid Processing System — Michigan Department of Health and Human Services' (MDHHS) web-based Medicaid Management Information System, the real-time system that adjudicates claims and houses provider enrollment.

CHAMPS is where the state-level work happens: enrolling as a provider, updating your record, checking beneficiary eligibility, submitting fee-for-service claims, requesting prior authorization, and managing contracts. MDHHS describes CHAMPS as being made up of several subsystems, including Provider Enrollment, Eligibility and Enrollment, Prior Authorization, Claims and Encounters, and Contracts Management. It is the front door to Michigan Medicaid's state layer — not the whole story, but nothing else works until your CHAMPS record exists.

What is MiLogin?

Before you can touch CHAMPS, you need to get into it — that is what MiLogin does. MiLogin is Michigan's secure sign-on layer, the login and identity system in front of CHAMPS (and other state services).

A few things trip people up here:

• Everyone who needs CHAMPS access needs their own MiLogin. MDHHS's guidance is that each user who works in CHAMPS obtains their own MiLogin user ID and password. You do not hand your login around the office.

• The person who submits the enrollment application becomes the Domain Administrator. The MiLogin user who files the provider enrollment application becomes the Provider Domain Administrator for that record — the person who assigns and removes access for everyone else in the organization.

• Access is granted by role, not by password sharing. CHAMPS uses access roles — for example, limited/view access, claims access, eligibility inquiry, and the Domain Administrator role itself. The right way to add a biller is to give them their own MiLogin and assign the correct role, not to share credentials.

The one thing to remember: MiLogin is the access layer. Having a MiLogin account is not the same as being enrolled, and being enrolled is not the same as being credentialed with a plan.

What CHAMPS enrollment actually does

Enrolling in CHAMPS establishes your state Medicaid provider record — MDHHS screens and enrolls you (and/or your group) into Michigan's Medicaid system as a recognized, screened provider.

Michigan requires this broadly: MDHHS's guidance is that all providers who serve Michigan Medicaid beneficiaries — including those in Medicaid Health Plan and Dental Health Plan networks — must be screened and enrolled in CHAMPS. So even providers who mainly work through managed care still need a CHAMPS enrollment underneath.

Once enrolled, you exist in the system as a screened Michigan Medicaid provider — able to check eligibility, submit and track fee-for-service (FFS) claims for services the state pays directly, request prior authorization, and manage your record and revalidation over time. You will also choose an enrollment type during this process (for example, individual/sole proprietor, rendering/servicing provider, or group), which shapes how you bill later. We cover enrollment types and the step-by-step application in the dedicated enrollment post.

What CHAMPS enrollment does not do

Here is the part that surprises people most: CHAMPS enrollment does not automatically put you in-network with the Medicaid Health Plans or the specialty behavioral health system. Enrollment screens you into the state system; it does not sign you into anyone's provider network.

Most Michigan Medicaid members are in managed care, not straight fee-for-service, so for a large share of your clients the payer is a Medicaid Health Plan or a PIHP — not MDHHS directly — and those organizations run their own networks with their own credentialing and contracting. Being enrolled in CHAMPS is the floor, not the finish line.

Skip the managed care step and you can end up fully enrolled in CHAMPS and still watch claims deny because the client's plan does not recognize you as in-network. This is the single most common Michigan Medicaid setup gap we see with therapy practices.

Where Medicaid Health Plans (MHPs) fit

Michigan delivers most Medicaid benefits through managed care. MDHHS groups its managed care organizations as Medicaid Health Plans (MHPs), Dental Plans, and Prepaid Inpatient Health Plans (PIHPs) for specialty mental health and substance use disorder services.

Medicaid Health Plans are the general managed care plans that cover most physical health services — and, depending on current policy, some behavioral health. Which MHPs are available depends on the county/region, and each member is enrolled in a specific plan.

For a therapist, the practical consequence is this: to be paid as in-network for a client enrolled in a given MHP, you generally have to credential and contract with that specific plan. Each plan runs its own process, paperwork, and timeline. Being in one plan's network does not put you in another's, and plan rules are not interchangeable — do not assume what worked for one MHP applies to the next. Because these requirements are plan-specific and change over time, confirm any one plan's rule on that plan's current provider page (we keep the plan-by-plan details in separate posts).

Where PIHPs and CMHSPs fit for behavioral health

This is the layer that makes Michigan different from many other states, and the one therapists most need to understand.

Michigan operates a specialty behavioral health "carve-out." For more involved or severe needs, behavioral health services are managed not by the regular Medicaid Health Plan but by a regional Prepaid Inpatient Health Plan (PIHP), working through local Community Mental Health Services Programs (CMHSPs) in each community. Here is how MDHHS frames the pieces:

• PIHPs are the regional entities MDHHS contracts with to manage and deliver Medicaid-covered specialty behavioral health services. They manage the network of behavioral health providers, including the CMHSPs.

• CMHSPs are the local, community-based organizations that actually deliver and coordinate much of this care.

• The specialty system serves populations such as adults with serious mental illness, children with serious emotional disturbance, people with substance use disorders, and people with intellectual and developmental disabilities.

The rough dividing line is acuity: mild-to-moderate needs are more likely to sit with the Medicaid Health Plan side, while higher-acuity or specialty needs are more likely the PIHP/CMHSP carve-out's responsibility. MDHHS publishes a coverage-responsibility framework to determine which entity is responsible, and that can depend on the setting and level of need, not just the diagnosis.

Two cautions worth flagging up front:

1. Do not oversimplify this. "Mild-to-moderate goes to the MHP, everything else to the PIHP" is a useful intuition, not a billing rule — actual routing depends on the assessment, program, setting, and current policy.

2. This is changing. As of this drafting (July 2026), MDHHS's Mental Health Framework — part of its MIHealthyLife / Comprehensive Health Care Program work — describes a shift toward using a standardized assessment of an enrollee's level of need to determine whether the MHP or the PIHP is responsible for their mental health care. Coverage-responsibility changes that had been scheduled around October 1, 2026 have been noted as temporarily delayed to allow more preparation. Treat any specific date or split as "verify current MDHHS policy before you rely on it." We track this in the dedicated Mental Health Framework post.

Fee-for-service vs. managed care vs. specialty behavioral health

Once you understand the layers, claim routing gets clearer. A Michigan Medicaid claim travels one of three lanes:

1. Fee-for-service (FFS) / CHAMPS — for services MDHHS covers directly, billed to the state through CHAMPS. This is the lane your CHAMPS enrollment opens on its own.

2. Medicaid Health Plan (MHP) — for managed care clients, billed to the client's plan under your contract with it (which is why credentialing matters).

3. PIHP / CMHSP — for carved-out specialty behavioral health, billed through the regional PIHP and its CMHSP network, on their terms.

Which lane applies depends on who the client is enrolled with, their level of need, the service, and current policy — so you verify eligibility and plan assignment in CHAMPS before the visit rather than guessing.

Why eligibility verification is step zero

One operational point prevents a lot of denials: the mihealth card is not proof of eligibility.

MDHHS is explicit that the mihealth card shows the beneficiary's name and ID number but does not indicate current eligibility and does not guarantee it. Before rendering services, you are expected to verify eligibility through the CHAMPS Eligibility Inquiry (via the web screens or an electronic 270/271 transaction). The response returns Benefit Plan ID(s) that tell you which program and coverage apply for that date of service — and, critically, which plan the client is assigned to.

That response tells you which of the three lanes you are in for that client, on that day. Skipping it is how practices submit clean-looking claims to the wrong payer.

Checklist: what to gather before you start

Getting organized up front saves weeks. Before you begin, pull together:

• NPI(s) — individual (Type 1) and, if you bill as a group, organizational (Type 2).

• Practice legal name, Tax ID/EIN, and W-9 details.

• Michigan professional license information for each rendering clinician.

• A current CAQH profile (most Medicaid Health Plans lean on CAQH for credentialing).

• Service locations and correspondence addresses.

• A plan for MiLogin and CHAMPS access roles — who is your Domain Administrator, and who needs their own login.

• Your list of target Medicaid Health Plans by the counties/regions you serve.

• Your behavioral health routing question answered: outpatient mild-to-moderate only, or specialty services that route through the PIHP/CMHSP system?

Action Steps for Providers

1. Create MiLogin accounts. Set one up for whoever will file the enrollment, and plan individual logins for everyone who will work in CHAMPS. Do not share credentials.

2. Enroll (or confirm enrollment) in CHAMPS. Complete the provider enrollment application and choose the correct enrollment type. The submitter becomes the Domain Administrator.

3. Assign CHAMPS access roles. Have your Domain Administrator grant each staff member the specific role they need (claims, eligibility inquiry, etc.) rather than reusing one login.

4. Verify eligibility before every Medicaid visit. Use the CHAMPS Eligibility Inquiry to confirm coverage and read the Benefit Plan ID and plan assignment; treat the mihealth card as identification only.

5. Map each client to a lane — FFS, MHP, or specialty PIHP/CMHSP — based on the eligibility response and current policy.

6. Credential and contract with the right Medicaid Health Plans for your managed care clients, and keep CAQH current.

7. Sort out behavioral health routing early. If any of your work is higher-acuity or specialty, contact your regional PIHP and local CMHSP about their network and requirements.

8. Track dates and follow-ups — revalidation, credentialing timelines, prior authorization status, and the evolving Mental Health Framework. Verify current MDHHS and plan policy before acting on anything date-sensitive.

Where Bomi Fits

Michigan Medicaid is a lot of moving parts, and most of the friction is operational rather than clinical. That is the part we take off your plate.

Bomi helps therapy practices keep these workflows straight — eligibility checks, claims submission and tracking, denials and appeals, credentialing workflows, payer follow-up, EOB review, and revenue operations — so clinicians spend more time with clients and less time reverse-engineering which payer owns a given claim. We are not a substitute for MDHHS, a Medicaid Health Plan, or a PIHP, and we do not guarantee enrollment approval, plan acceptance, or reimbursement — what we do is help you run the process correctly and consistently.
