How to file an external review in Wisconsin
In Wisconsin, external review is called independent review and runs through state-certified Independent Review Organizations (IROs) overseen by the Wisconsin Office of the Commissioner of Insurance (OCI), not the federal HHS process. After your health plan issues its final grievance decision, you have four months (120 days) to request independent review. You ask your insurer to forward your file to a certified IRO, which assigns an independent clinical reviewer. A standard review takes up to 30 business days; an expedited review for urgent situations must be decided within 72 hours. The IRO's decision is binding on both you and the insurer, and there is no cost to you because the insurer pays the IRO's fees.
Wisconsin appeal questions
How do I file for an independent (external) review in Wisconsin?
First complete your health plan's internal grievance process and obtain its final written decision. Then submit a request for independent review to your insurer, which is required to send your file to a state-certified Independent Review Organization (IRO). The Wisconsin Office of the Commissioner of Insurance (OCI) certifies the IROs and can answer questions at its consumer assistance line.
What is the deadline to request independent review in Wisconsin?
You generally have four months, which is 120 days, from the date your health plan's final grievance decision was provided to you. This single window applies to medical necessity, experimental or investigational, preexisting condition, and rescission disputes. Missing the deadline can forfeit your right to independent review, so it is important to request it promptly.
Does an independent review in Wisconsin cost me anything?
No. There is no fee to you for requesting an independent review in Wisconsin. State law requires your insurance company to pay the IRO's fees, so the clinical reviewer's cost is covered by the insurer rather than the patient.
Is the IRO's decision binding, and what if I have a self-funded employer plan?
Yes. The independent reviewer weighs your medical records and your plan's coverage terms, and its decision is binding on both you and the insurer. However, Wisconsin's independent review law generally does not apply to self-funded employer plans governed by ERISA, which follow a separate federal external-review process. If you are unsure of your plan type, check your benefits documents or ask your HR department.
