Illegal Medical Billing · Michigan
Is a hospital billing you after your insurance already paid the contracted rate in full in Michigan?
Freeze the bill, halt collections, and force the charges off your account.
Under federal law, this exact tactic violates ERISA + No Surprises Act anti-balance-billing provisions. In-network providers cannot 'balance bill' the difference between their charge and the contracted allowed amount — that difference is a contractual write-off, not patient responsibility. Use our engine to generate a professional Medical Bill Appeal in under 60 seconds.
Your rights in Michigan
Hospital billing departments rely on your confusion to collect illegal charges. Here is the exact consumer rights you hold over them right now.
Federal protection — ERISA + No Surprises Act anti-balance-billing provisions
Once an in-network provider accepts the contracted rate as payment in full, billing the patient for the contractual write-off is a breach of the provider's network agreement.
Michigan adds: Michigan Surprise Medical Billing Act, MCL § 333.24501
In-network cost-share cap + insurer-provider arbitration. State remedies stack on top of federal No Surprises Act protections.
Remedy
Charge must be zeroed out; the provider violated its network contract and the bill is unenforceable.
Evidence to lock in your appeal
Save the EOB showing 'patient responsibility = $0' or the in-network adjustment, plus the bill showing the provider charging you the write-off amount.
Crucial tactic: If the hospital sends an illegal balance bill to a collector, sending a formal written dispute immediately flags the account as "contested" — halting credit reporting and pausing collection activity while their legal team reviews the statutory violations.
