Medical Billing Services in Michigan

Michigan practices bill in a state where the payer mix is never simple. A rehabilitation group in Grand Rapids, a behavioral health clinic in Detroit, and a cardiology practice in Ann Arbor may all treat Medicaid patients — but where a claim goes, and whether it pays, depends on rules that differ from most states. Add Medicare and a shelf of commercial plans, each with its own authorization and filing requirements, and billing becomes constant sorting: right payer, right program, right rules, every time.

Fastora Medical Billing Solutions handles that work for Michigan practices, from solo therapists to multi-location groups, as part of our billing support for practices across the United States. This page explains how billing works in Michigan, where practices here lose money, and how we take the workload off your team.

The billing problems Michigan practices actually face

The first problem is destination. In Michigan, “bill Medicaid” is not one instruction. Depending on the patient and the service, the claim may belong to a Medicaid Health Plan, a regional behavioral health organization, or the state itself — and a claim sent to the wrong one is denied even when the service is covered and documented. Practices that treat Medicaid as a single payer learn this one denial at a time.

The second problem is volume against capacity. Michigan practices run lean front offices, and billing is what slips when the schedule fills: eligibility checked late or not at all, authorizations untracked, denials set aside, accounts receivable aging quietly. None of it shows up as one dramatic loss. It shows up as services delivered, documented, and never paid.

Michigan Medicaid: MDHHS, health plans, and a behavioral health split

Michigan Medicaid is administered by the Michigan Department of Health and Human Services (MDHHS). Most people who receive full Medicaid benefits are required to enroll in a Medicaid Health Plan (MHP). MDHHS pays each plan a monthly capitation, and the plan — not the state — reimburses most medical services for its members. So most Michigan Medicaid claims go to the member’s plan, under that plan’s own claim requirements, authorization rules, and billing policies. The Healthy Michigan Plan, the state’s Medicaid expansion program, works through this same structure.

Fee-for-service still exists, but it is the smaller door. Members are covered on a fee-for-service basis until they enroll in a plan, and some populations — nursing facility residents and PACE participants among them — sit outside plan enrollment, along with services carved out of the plan benefit. Those claims go to MDHHS through CHAMPS, the state’s claims and enrollment system. Which door applies is the first billing decision on every Michigan Medicaid claim.

Behavioral health is where Michigan billing genuinely differs — and where claims most often go wrong. The split runs by level of need. A member’s Medicaid Health Plan covers outpatient mental health care for mild-to-moderate needs in office and clinic settings. Specialty mental health services, and substance use disorder services, are managed separately by regional Prepaid Inpatient Health Plans (PIHPs), delivered largely through Community Mental Health Services Programs. Health plans are not responsible for substance abuse services at all; acute medical detoxification, for example, is reimbursed directly by MDHHS.

So the same practice can bill three different destinations for three patients in the same waiting room — the health plan for a mild-to-moderate therapy session, the PIHP for a specialty service, the state for detox. Route one claim by habit instead of by level of need and it comes back denied, not because the care was uncovered, but because it was sent to the wrong organization. Getting that routing right, claim by claim, is central to our substance abuse billing services and to our behavioral health billing for Michigan practices.

Medical billing and coding services under one roof

Clean claims start at the charge. A large share of denials trace back to coding: a code that does not match the documentation, a missing modifier, therapy time converted to units incorrectly, or a behavioral health session coded at the wrong level of service. Fastora’s coding review compares what was documented with what is about to be billed, so errors are caught while they are still cheap to fix. Corrected claims and reprocessing requests run through the same workflow. That combination — billing and coding reviewed together — is what practices mean by medical billing and coding services in Michigan, and it is how we structure the work.

What Fastora handles for Michigan practices

Fastora handles the full revenue cycle for Michigan practices — the end-to-end work often called revenue cycle management — or just the stages your own team cannot keep up with:

• Claims submission and follow-up. Claims are prepared, scrubbed, and submitted electronically — to the correct plan, PIHP, or state system — then tracked until each one resolves.
• Denial management and appeals. Denials are worked by reason, corrected, and appealed where the documentation supports it, so recoverable revenue is not written off by default.
• Eligibility verification. Coverage is checked before the visit, including which organization — health plan, PIHP, or fee-for-service — is responsible for the service.
• Prior authorization. Authorizations are requested and tracked so services are not delayed or denied for a missing approval.
• Accounts receivable recovery. Aged claims are reviewed, prioritized, and followed up systematically instead of aging out.
• Payment posting and reconciliation. Payments and ERAs/EOBs are posted and reconciled — also how underpayments surface when a plan pays below the contracted rate.

That work is backed by 5+ years of medical billing experience, a roster of 50+ active clients, and relationships with 100+ satisfied MDs. On pricing, Michigan practices choose between two arrangements: a percentage of collections, or a flat monthly fee — whichever fits the practice better.

Specialties we support in Michigan

Behavioral health, psychiatry, psychology, and counseling. This is Michigan’s defining billing specialty, because the payer depends on the patient’s level of need. Mild-to-moderate outpatient care bills to the member’s health plan; specialty services route to the regional PIHP. We confirm the destination before the claim is built, then handle the authorizations, session coding, and documentation follow-up these claims turn on — across Medicaid, Medicare, and commercial plans.

Physical, occupational, and speech therapy — rehabilitation. Michigan’s rehabilitation volume is substantial, especially around Detroit and Grand Rapids, and therapy billing is unforgiving arithmetic: timed units, modifiers, visit limits, and documentation supporting every unit billed. Our rehabilitation billing services keep therapy coding and claims consistent, so small errors stop repeating across every visit on the schedule.

Pain management. Pain practices bill procedure-heavy claims that draw authorization requirements and documentation scrutiny, with little room for coding drift. We handle the claim preparation, authorization tracking, and appeal work behind our pain management billing, so procedure revenue does not stall on paperwork.

Cardiology and substance use disorder treatment. Michigan cardiology groups manage high-volume testing and procedure billing across hospital and office settings, where a coding or authorization miss repeats at scale. Substance use disorder programs work inside the PIHP structure described above, with level-of-care documentation and recurring authorizations that pull clinical staff into billing work. We bill for both.

Billing support across Michigan

Detroit

Detroit is Michigan’s largest practice market: major health systems alongside a deep community of independent specialty, therapy, and behavioral health practices, with heavy Medicaid managed-care volume throughout. The daily challenge is routing — health plan, PIHP, or state — across a large, varied patient base, and we build that routing into eligibility verification.

Grand Rapids

Grand Rapids anchors healthcare in West Michigan, with a growing medical corridor and an especially strong rehabilitation and therapy sector. Group practices here have expanded faster than their back offices, and volume exposes every gap in authorization tracking and denial follow-up. Fastora gives Grand Rapids practices a full billing team behind them without adding billing headcount.

Ann Arbor

Ann Arbor’s practice community is shaped by academic medicine: university-linked clinics, specialty and psychiatry practices, and research-affiliated providers alongside independent offices. Payer mixes are complex, and referral and authorization patterns reflect the academic setting. We support Ann Arbor practices with careful coding review and follow-up that does not depend on one person’s memory.

Lansing

As the state capital, Lansing’s payer mix carries a large public-sector workforce alongside commercial plans and Medicaid. Most practices are small to mid-sized offices drawing patients from surrounding mid-Michigan counties — often without a dedicated billing department. Handing billing to a dedicated team is often the difference between claims that get worked and claims that quietly age out.

Kalamazoo

Kalamazoo is the regional hub for southwest Michigan, with a notable behavioral health and substance use treatment community serving a wide ring of smaller counties. Practices here deal directly with PIHP routing, on top of the usual commercial and Medicare workload. We handle that routing and follow-up so clinical staff stay focused on care.

Frequently asked questions

Who do we bill for a Michigan Medicaid patient — the state or a health plan?

Usually the health plan. Most people with full Michigan Medicaid benefits enroll in a Medicaid Health Plan, which pays for their care — so claims go to the member’s plan, under that plan’s rules. Fee-for-service billing to MDHHS applies to members not yet enrolled, populations excluded from plan enrollment, and services carved out of the plan benefit. We confirm the arrangement at eligibility verification.

Why do behavioral health claims go to a different payer in Michigan?

Because Michigan splits behavioral health by level of need. Medicaid Health Plans cover outpatient mental health care for mild-to-moderate needs, while specialty mental health and substance use disorder services are managed by regional Prepaid Inpatient Health Plans (PIHPs) through Community Mental Health Services Programs. A specialty claim sent to the member’s health plan is denied for wrong payer even when the service is covered. We check the level of need and route accordingly.

What is the Healthy Michigan Plan?

The Healthy Michigan Plan is Michigan’s Medicaid expansion program, administered by MDHHS. Its members are covered through the same Medicaid Health Plan structure as other full-benefit members, so the same plan-based rules apply — including the behavioral health split.

What is the timely filing deadline for Michigan Medicaid claims?

It depends on the destination. For fee-for-service claims, the MDHHS Medicaid Provider Manual requires a claim to be received by MDHHS within 12 months of the date of service, and claims must be resolved within that year unless an exception applies, such as retroactive eligibility. Claims billed to a Medicaid Health Plan follow that plan’s own filing policies instead. We track both so neither quietly expires.
