What areas does MMSM serve?
Medical Management Systems serves healthcare providers across the entire state of Michigan. Billing, credentialing, and enrollment are handled securely and remotely, so we partner with physician practices, surgical groups, EMS agencies, and urgent care clinics anywhere in Michigan. We’re headquartered in Lansing — centrally located in mid-Michigan — with decades of deep roots serving providers statewide, including Grand Rapids, Detroit, Ann Arbor, Flint, Kalamazoo, Saginaw, and Traverse City.
A statewide billing & credentialing partner
Medical Management Systems partners with healthcare providers across the entire state of Michigan — physician practices, surgical groups, EMS agencies, and urgent care clinics. Billing, credentialing, and provider enrollment are digital, document-driven processes, and we deliver them securely and remotely, so where you are in Michigan is never a barrier to working with us.
Whether you run a single-physician practice in one town or a multi-site organization spanning several counties, you get the same thing: an accountable, U.S.-based team that treats your revenue like its own — never an offshore call center.
How we work with providers across Michigan
- Secure, remote delivery — we work in HIPAA-compliant systems and integrate with your existing EHR/PM software, wherever you are in the state.
- Michigan-specific expertise — we manage Michigan Medicaid (CHAMPS), regional payers, and the enrollment rules that apply to Michigan providers.
- Close communication — named account managers reachable by phone, email, and video, working in your time zone.
- One connected team — billing, credentialing, and enrollment under one roof, so nothing falls between vendors.

A local partner who knows Michigan
Healthcare billing isn’t one-size-fits-all. Michigan Medicaid, regional payers, and local practice patterns all shape how claims should be handled — and a partner who works in your time zone, in U.S.-based systems, catches things a distant or offshore vendor never will. Being centrally located in Lansing means we’re never far from the providers we serve.
