Wisconsin program
An outside review of a treatment denial (independent review)
A reviewer outside your health plan can reconsider an eligible treatment denial.
What it is
A reviewer outside your health plan can reconsider an eligible treatment denial.
If your plan refuses a treatment, a reviewer outside the plan can overturn it. Wisconsin's route covers insured plans and some public-employer plans; the plan's own grievance usually comes first.
Eligibility rules
- Wisconsin-insured plans use the state route, and Wisconsin’s public-plan statutes also extend it to specified state and participating municipal plans. A self-funded private-employer plan generally uses federal rules instead; “self-funded” alone does not answer the public-plan question.
- The written request goes to the insurer within four months of receiving the final grievance decision.
What you get
- An outside review at no cost to the family.
- An urgent decision within 72 hours when the requirements are met. Standard reviews have a longer timetable.
If you decide to apply
- Ask the plan for its final grievance decision and the address for independent-review requests.
- Bring the denial letters and ask the oncology team for a medical-necessity letter, including any reason treatment cannot wait.
Your insurer for the review address; Wisconsin insurance regulator: 800-236-8517 · Official page ↗
Good to know
You have four months from the day the plan's final grievance decision arrives, so keep the envelope or email and note the date.
Other details
- The insurance regulator's consumer number is 800-236-8517. The oncology team's clinical explanation supports the medical review.
- Outside review is for a plan saying a treatment is not medically necessary or is experimental, not for a billing dispute or a benefit the plan never covered. When waiting could harm your child, the urgent route can skip the plan's own grievance. A standard decision takes about 30 business days once the papers are exchanged.
Official sources
“If our plan denies treatment, would outside review help, which route and deadline apply, and could you help us request it when appropriate?”
Why I’m asking: I want to understand the appeal route without assuming our plan falls under the state process.

Who does what
The three parts, side by side. The agency decides; nobody on this page does.
You
The written request is generally due within four calendar months after receipt of the final grievance decision. Urgent review and permitted exhaustion exceptions have separate rules. Four calendar months is not a fixed 120-day period.
Your social worker
The oncology team writes why the treatment is medically necessary and supports an urgent request.
The care team
The clinical letter is what the outside reviewer reads.
- Who decides
- An independent review organisation outside the plan.
- Ask your social worker
- “The plan has refused this. Can we finish the internal grievance and then ask for an independent review, on the urgent track if treatment cannot wait?”
How to apply
First step: Ask the plan in writing for its final grievance decision and the address to send a review request to.
- Ask the plan in writing for the final grievance decision and the review address.
- If treatment cannot wait, ask for the expedited track by name.
Official application / program page ↗
Where it starts: Finish the plan's internal grievance, then send a written request to the address on the final decision. Ring the insurance regulator on 800-236-8517 if you are stuck.
What to gather
- The denial letters
- The final grievance decision
- The oncology team's letter of medical necessity
How long: Standard decisions are due within 30 business days after the statutory information-exchange deadlines; qualifying expedited decisions are due within 72 hours.
What a yes looks like
The outside reviewer overturns the refusal and the plan has to cover it.
What a no looks like, and the next move
The reviewer agrees with the plan. Ask the team about a different route to the same treatment, and ring the regulator on 800-236-8517.
Watch out
- The written request is generally due within four calendar months after receipt of the final grievance decision. Urgent review and permitted exhaustion exceptions have separate rules. Four calendar months is not a fixed 120-day period.
- Self-funded private employer plans use a different route; ask HR which kind yours is.
- A school district, city or state plan may follow its own route; ask the administrator in writing.
