Medical Billing Services in Michigan
Michigan's commercial market runs through Blue Cross Blue Shield of Michigan — a nonprofit mutual with a share so large that its policies function as the state's de facto billing standard — with Priority Health (Corewell) and HAP (Henry Ford) as the provider-owned challengers. Medicaid gives providers a full 12 months to file through CHAMPS, with most members in managed care plans like Meridian, Molina and McLaren. Michigan's clean claim law puts a 45-day clock on payers with 12% annual interest on late payment, and the state's auto no-fault system still generates a distinctive medical billing stream — post-reform fee schedules and litigation-adjacent claims that most out-of-state billers have never touched.
Michigan Medicaid: filing rules that decide whether you get paid
Administered by the Michigan Dept. of Health and Human Services (MDHHS)
Michigan Medicaid fee-for-service claims carry a 12-month window from the date of service, filed through the CHAMPS (Community Health Automated Medicaid Processing System) portal, which also handles enrollment, revalidation and group affiliations. Most members are enrolled in Medicaid Health Plans — Meridian (Centene), Molina, McLaren, UnitedHealthcare Community Plan, Blue Cross Complete and others — whose filing limits commonly run 90 days to 12 months depending on the plan. The Healthy Michigan Plan (the state's expansion population) bills like standard Medicaid managed care but keeps its own eligibility category, and behavioral health runs through regional PIHPs — a carve-out structure that surprises billers coming from carve-in states.

The payers we bill every day in Michigan
Michigan billing rules that move real money
Michigan clean claim law (MCL 500.2006)
Michigan requires payers to pay clean claims within 45 days of receipt; untimely payment accrues 12% annual interest owed to the provider. Payers must notify providers of defects within a defined window rather than letting claims age silently — a notice requirement worth enforcing in writing.
Auto no-fault medical billing
Michigan's 2019 no-fault reform introduced fee schedules tied to Medicare rates for auto injury care and changed how attendant care and post-acute services are reimbursed. Auto claims still bypass health plans entirely and bill the auto insurer — with their own forms, timelines and dispute processes — and they remain a meaningful revenue line for Michigan orthopedics, PM&R, neurology and PT practices.

Credentialing & enrollment in Michigan
Physician licensing in Michigan runs through the Michigan Board of Medicine (LARA), and payer enrollment is its own workstream on top of it — state Medicaid enrollment, CAQH upkeep, and individual plan contracting each on their own timeline. Our credentialing service manages the full stack for Michigan providers, and our credentialing calculator estimates realistic timelines by payer.
Michigan billing FAQs
What is the timely filing limit for Michigan Medicaid?
12 months from the date of service for fee-for-service claims through CHAMPS. Medicaid Health Plans set their own limits — commonly 90 days to 12 months — so verify each plan's provider manual for managed care members.
What does Michigan's clean claim law require?
Under MCL 500.2006, clean claims must be paid within 45 days of receipt, and late payments accrue 12% annual interest payable to the provider. We track payer aging against that clock and demand interest where it's owed.
Do you bill Michigan auto no-fault claims?
Yes — auto injury claims bill the auto insurer under Michigan's post-reform fee schedules, not the patient's health plan. We handle the no-fault forms, fee schedule pricing and follow-up, which matters for ortho, PM&R, neurology and therapy practices.
Do you work with Priority Health and HAP?
Yes. Alongside BCBSM, we bill Priority Health and HAP daily — including their distinct auth lists and appeal routes — plus the Medicaid plans (Meridian, Molina, McLaren, Blue Cross Complete) that dominate managed care enrollment.
