Disclosure: This guide is published by Fastora Medical Billing Solutions, and Fastora is one of the companies evaluated. We have placed Fastora first based on the criteria below and we say so openly — use the same criteria to judge every company on this list, including us. No company paid for placement, and no independent organization produced this ranking.
Michigan billing turns on choosing the right door. Michigan Medicaid is administered by the Michigan Department of Health and Human Services (MDHHS), and most people with full Medicaid benefits must enroll in a Medicaid Health Plan (MHP) — MDHHS pays the plan a monthly capitation, and the plan, not the state, pays the provider. Fee-for-service still exists for excluded populations and carved-out services, billed to MDHHS through CHAMPS. Behavioral health splits again: health plans cover outpatient mental health 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. This guide compares seven companies that bill for Michigan practices in 2026. If you want the service itself rather than a comparison, start with Fastora’s medical billing services in Michigan.
How we evaluated these companies
- Michigan Medicaid routing fluency — does the company distinguish Medicaid Health Plan claims from fee-for-service claims billed through CHAMPS, and work each plan’s own rules?
- Behavioral health split competence — Michigan routes mild-to-moderate outpatient mental health to the health plan and specialty mental health and substance use services to the PIHP/CMHSP system; can the company bill both sides correctly?
- Specialty coding depth — Michigan volume concentrates in rehabilitation and therapy, pain management, cardiology, and behavioral health; coding has to match the specialty.
- Denial and A/R work — who appeals, rebills, and chases aged receivables, versus who only reports them?
- Pricing clarity — is the model published, and does the quoted scope include credentialing, authorizations, and old A/R?
- Practice-size fit — a solo therapy practice, a multi-site group, and a hospital-based organization need different things from a partner.

1. Fastora Medical Billing Solutions
Fastora is a remote billing partner for Michigan practices — it has no Michigan office, and its Michigan work is built around the state’s three-destination Medicaid structure. Which door applies — the member’s Medicaid Health Plan, MDHHS fee-for-service through CHAMPS, or the PIHP system for specialty behavioral health — is the first decision on every Michigan Medicaid claim, and Fastora’s workflow makes that routing check part of billing operations rather than a lesson learned from denials. The service covers the full cycle — eligibility verification, coding, claims submission, denial management, A/R recovery, payment posting, and credentialing support — including dedicated rehabilitation billing services for Michigan’s large therapy sector. Fastora also publishes its billing services across America for practices with locations in more than one state.
Fastora’s work rests on more than 5 years in medical billing and revenue cycle management, support for 100+ physicians, and 50+ active clients. Pricing is a percentage of collections or a flat monthly fee, quoted after a free billing assessment with scope clear before you commit.
Strengths: the MHP / fee-for-service / PIHP routing question is treated as an operational checkpoint, and the full cycle including A/R recovery sits in one service. Considerations: Fastora serves Michigan remotely, with no Michigan office — practices that want a local team on site should weigh that.
Best fit: independent and group practices, including rehabilitation, therapy, and behavioral health practices, that want routing, coding, and denial work handled by one team.
2. MediBillMD
MediBillMD is a Dallas, Texas–headquartered billing and credentialing company, formed in 2023, serving practices in all 50 states including Michigan. Its published scope is end-to-end: billing and coding, claim scrubbing and submission, denial management, A/R management, payment posting, old A/R recovery, billing audits, and credentialing, across 60+ specialties with AAPC-certified coders. It publishes its pricing model — a percentage of collections, with rates advertised as low as 2% of net monthly collections.
Strengths: a published low starting rate, broad specialty coverage, and credentialing and old A/R recovery inside one service. Considerations: it is a young company headquartered outside Michigan — ask how Michigan plan rules are staffed and which services the lowest advertised rate actually includes.
3. Keizer Solutions
Keizer Solutions Inc. is a Southfield-based healthcare services company founded in 2010, serving hospitals, health systems, and physician groups. Its service list is broader than billing alone: billing and coding, A/R and denial management, credit balance resolution, authorization management, credentialing, business intelligence, and medical transcription. Its published workflow runs from eligibility checks ahead of appointments through charge entry, payment posting, denial follow-up, and monthly A/R reporting, with clients able to view work in real time.
Strengths: authorization management, credentialing, and transcription under the same roof as billing, with a Detroit-metro base. Considerations: the breadth cuts both ways — practices that only need billing should scope the engagement tightly.
4. Genesis Medical Billing
Genesis Medical Billing (Gen Med) is a Constantine, Michigan company specializing in billing and coding for behavioral health practices. Its focus is personalized service for therapy providers, from claim submission to payment follow-up, with an emphasis on communication about where every claim stands. The firm’s founder holds CPC and BSCS credentials, serves as president of the AAPC’s Kalamazoo chapter, and has specialized in mental health and ABA billing — directly relevant in Michigan, where specialty behavioral health claims route through the PIHP/CMHSP system, not the member’s health plan.
Strengths: a genuine behavioral health specialization, certified leadership, and a small-team model built around direct communication. Considerations: practices outside behavioral health and therapy should confirm fit, and larger organizations should confirm capacity before committing high claim volume.
5. Reliant Billing Services
Reliant Billing Services (RBS) is a Farmington Hills company founded by people with first-hand experience of practice billing frustrations. It offers certified coding, A/R recovery, credentialing, and IT consulting alongside core billing, and it publishes the payers it works with — including Medicare, CHAMPS (Michigan Medicaid’s system), and Michigan plans such as HAP, Meridian, and Molina. Its named specialties include urgent care, internal medicine, oncology, cardiology, primary care, radiology, and pediatrics.
Strengths: a Michigan base with published fluency in the state’s payer mix, plus credentialing and A/R recovery in the same engagement. Considerations: it is a locally focused firm — multi-state groups should confirm how out-of-state payer work is handled.
6. eClaim Solution
eClaim Solution is a Delaware-based national billing company with a dedicated Michigan operation covering cities statewide, from Detroit and Grand Rapids to Lansing and Flint. Its published Michigan scope is end-to-end: eligibility checks, credentialing support, prior-authorization checks, coding by certified coders, claim submission, denial management, and A/R follow-up with payment posting. Pricing depends on practice size and type, and it offers a free billing audit for Michigan providers.
Strengths: a complete published service list with credentialing and authorization checks included, plus a free audit as a starting point. Considerations: pricing is quoted rather than published — get the full scope in writing.
7. Medical Billers and Coders
Medical Billers and Coders (MBC) is a long-running national billing company whose coding specialists it describes as having over 25 years of experience. It serves Michigan practices across Detroit, Grand Rapids, Warren, Sterling Heights, Flint, and smaller communities statewide, with a published service list covering claim filing, coding analysis, denial management, payment posting, patient statements, insurance follow-up, A/R reporting, and provider enrollment support. It works with a wide range of practice-management and EMR software.
Strengths: nationwide scale with explicit Michigan city coverage and a broad service menu. Considerations: as with any large national firm, confirm the specialty team assigned to your account and how Michigan rules — the PIHP split in particular — are handled.
How to choose for your Michigan practice
Start with your Medicaid mix, because Michigan makes the routing decision unavoidable. If Medicaid is a meaningful share of revenue, ask each candidate to walk through three claims: a medical claim for a health-plan member, a fee-for-service claim through CHAMPS, and a specialty behavioral health claim that belongs to the PIHP system. A company that cannot keep those destinations straight will teach you the difference through denials. Then compare scope at the same definition — a lower percentage that excludes credentialing, authorizations, and old A/R is not cheaper than a higher one that includes them. Finally, match the company to your specialty and size: a behavioral health specialist, a Detroit-metro full-service firm, and a national provider are different relationships, and the right one fits your claim mix.
Frequently asked questions
What makes Michigan Medicaid billing different from other states?
Michigan splits Medicaid three ways. Most people with full benefits are enrolled in a Medicaid Health Plan, which MDHHS pays a monthly capitation and which pays providers under its own billing policies. Excluded populations and carved-out services bill fee-for-service to MDHHS through CHAMPS. And behavioral health splits by level of need: health plans cover outpatient mental health for mild-to-moderate needs, while specialty mental health and substance use services run through regional Prepaid Inpatient Health Plans and Community Mental Health Services Programs. A claim sent to the wrong destination denies even when the service is covered.
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 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 — a Michigan billing company has to track both clocks.
Who do we bill for behavioral health services in Michigan?
It depends on the level of need. Outpatient mental health for mild-to-moderate needs is the member’s Medicaid Health Plan’s responsibility. Specialty mental health and substance use disorder services are managed by the regional Prepaid Inpatient Health Plan, delivered largely through Community Mental Health Services Programs — and health plans are not responsible for substance abuse services at all; acute medical detoxification is reimbursed directly by MDHHS.
How much does it cost to outsource medical billing in Michigan?
Most companies price either as a percentage of collections or as a flat monthly fee. One company on this list publishes rates as low as 2% of net monthly collections; others quote by practice size and type. Percentages are only comparable at equal scope: confirm whether credentialing, authorizations, patient statements, and old A/R recovery are inside the rate or billed separately. Fastora quotes a percentage of collections or a flat monthly fee after a free billing assessment.
Does my billing company need to be located in Michigan?
No. Claims are filed electronically, and what matters is whether the company works Michigan’s rules correctly — the health-plan versus fee-for-service split, the PIHP behavioral health carve-out, and plan-specific filing policies. A Michigan office can help with payer familiarity, but a remote company with disciplined routing checks will outperform a local one without them.
Can a new billing company take over our old accounts receivable?
Most full-service companies will work aged A/R as part of onboarding or as a defined add-on — several companies on this list publish old A/R recovery explicitly. Get the scope in writing: which aging buckets are included, how far back they will pursue, and whether recovery work is inside the standard rate or priced separately. In Michigan, check the clock first: fee-for-service claims must be resolved within 12 months of the date of service.
Conclusion
Michigan rewards billing companies that treat claim routing as a daily discipline, not a default. Compare the seven companies above on the criteria that match your payer mix — health-plan versus fee-for-service fluency, PIHP behavioral health competence, specialty coding depth, real denial and A/R work, and a pricing scope you can verify line by line.
