A locally owned Michigan billing and credentialing company that treats your revenue like our own.
Who is Medical Management Systems of Michigan?
Medical Management Systems of Michigan, Inc. (MMSM) is a locally owned medical billing and provider credentialing company headquartered in Lansing, Michigan, founded in 1984. For more than 40 years, MMSM has helped physicians and other healthcare providers, surgical groups, EMS agencies and municipalities, and urgent care clinics across Michigan increase collections, reduce denials, and stay compliant, with Certified Professional Coders and Billers you can actually reach.
Four decades, one mission: get Michigan providers paid
Medical Management Systems of Michigan was founded in 1984 on a simple idea: healthcare providers deserve a billing partner who treats their revenue with the same care they treat their patients. More than 40 years later, that’s still exactly what we do.
We’re a locally owned, Lansing-based team that Michigan physicians, nurse practitioners, PAs, surgeons, EMS agencies, municipalities, and clinics trust with the lifeblood of their organizations: getting paid.
Certified people who know your specialty
Our billers and coders are Certified Professional Coders (CPC) and Certified Professional Billers (CPB). They bill a wide range of specialties every day, including primary care, surgery, behavioral health, urgent care, and EMS, for physicians, nurse practitioners, and physician assistants, across Medicare, Medicaid, Blue Cross Blue Shield of Michigan, and commercial payers, and in the practice-management systems you already use. That depth is why practices also come to us for staff training, provider documentation training, and chart audits.

What we believe
Your revenue is personal. Every denied or underpaid claim is money you earned. We chase it like it’s ours.
Transparency builds trust. You should always know your clean-claim rate, your days in A/R, and your net collections, with no black boxes.
Specialty expertise matters. Surgery, behavioral health, EMS, and urgent care each have their own rules. Generic billing leaves money behind.
People you can reach. Your account is handled in the U.S. by a named team you can call, not routed to an offshore call center.
What we do
We provide a complete, connected revenue cycle for the providers we serve:
Because all of it lives under one roof, your credentialing, enrollment, and billing actually talk to each other, so the moment a provider is approved, we’re billing.
Built for Michigan
We’re based in Lansing and serve providers from Grand Rapids to Detroit, the Tri-Cities to Traverse City. Michigan is home, and it’s where we focus every day. See the areas we serve.

Answers
Frequently asked questions
Straight answers to the questions providers ask us most. Don't see yours? Just ask.
How long has MMSM been in business?
MMSM was founded in 1984, more than 40 years ago. We’ve spent four decades focused on one thing: helping Michigan healthcare providers get paid correctly and on time, through every major change in coding, compliance, and payer rules.
Is MMSM locally owned?
Yes. We’re locally owned and based in Lansing, Michigan. When you call, you reach people here, not a routing menu to an overseas team.
What makes MMSM different from national billing companies?
Expertise and accountability. Our coders and billers are CPC and CPB certified, with deep experience across specialties, payers, and practice-management systems. We also train staff, train providers on documentation, and audit charts, which few billing companies do. National vendors often treat your account as one of thousands; we assign named account managers, work every denial, and report transparently every month.
