Disputing a Medical Bill in Michigan: Start With Your Records
Why records come before arguments
You cannot argue that a service was not provided, or was billed at the wrong level, without seeing what the chart says. The HIPAA right of access lets patients request their medical records and, generally, billing records that are part of the designated record set. Providers must generally respond within 30 days.
What to ask for
Make the request in writing and name the date of service.
- The itemized bill with dates, descriptions and codes.
- The records for the visit, such as visit notes and orders.
- Any record showing which services were actually performed.
- Your account ledger, showing payments and adjustments.
Matching the chart to the bill
Once the records arrive, read the bill against them. Look for services billed that the notes do not mention, a visit level that seems higher than the complexity described, the wrong date or patient, and quantities that do not match. These are the kinds of clerical and coding errors a written dispute can point to.
You do not need to interpret clinical details. Note the mismatch, quote the line, and ask the provider to explain or correct it.
Which Michigan office to contact
The Michigan Department of Insurance and Financial Services takes consumer complaints about insurers and the plans it regulates. For unfair or deceptive billing practices, the Michigan Attorney General's consumer protection office may help. For surprise billing under federal law, the CMS No Surprises Help Desk is 1-800-985-3059.
Federal and state rules
The No Surprises Act protects most privately insured patients in emergencies and at in-network facilities, with ground ambulances not covered. If a collector contacts you, a written dispute within 30 days of the validation notice can pause collection. Michigan law may add protections, so check the department's website for your plan type.

Who takes insurance complaints in Michigan?
The Department of Insurance and Financial Services takes consumer complaints about insurers. If your employer self-funds your plan, the state regulator may not have authority, so check your plan documents or ask HR which appeal route applies.
