Michigan program

An outside review of an insurance denial (DIFS)

Michigan DIFS can send an eligible insurance denial to an independent reviewer whose decision binds the insurer.

What it is

Michigan DIFS can send an eligible insurance denial to an independent reviewer whose decision binds the insurer.

An insurance plan's final denial is not always the final word. On a plan Michigan regulates, DIFS sends the denial to an outside reviewer who can overturn it. A plan where the employer pays its own claims uses a federal route instead; one question to HR settles which.

Eligibility rules
  • The internal plan appeal normally comes first. A waiver may apply when the insurer fails to follow its process.
  • Non-governmental self-funded plans and the excepted products listed on FIS 0018 are excluded.
What you get
  • A free independent review that can require the insurer to reverse a denial.
  • An urgent review decided in 72 hours when the urgent requirements are met.
What the help covers
  • The independent review decision binds the insurer for an eligible case.
If you decide to apply
  1. Ask the hospital social worker to check the final denial and your plan type with DIFS.
  2. If you choose review, submit FIS 0018 or the online form with denial letters and the medical support.
  3. For urgent treatment, ask the oncologist about the required urgency letter and the expedited plan appeal.

Michigan DIFS and an independent review organization: 877-999-6442 · Official page ↗

If you decide to apply
  • For the urgent route, DIFS requires an expedited internal appeal to have been requested, contact within 10 days after receipt of the adverse determination, a physician’s urgency statement and treatment not yet delivered. The family need not wait for the internal expedited appeal to finish before asking DIFS about urgent external review.
  • The 72-hour urgent clock does not remove those entry requirements.
Good to know

The 127 days run from the day you receive the final denial, so keep the notice and the envelope. DIFS on 877-999-6442 can confirm your exact deadline.

Other details
  • A Medicaid denial has a different appeal route. An insurer’s logo does not alone identify whether an employer plan is self-funded.
Official sources
Ask your social worker

“If a treatment denial reaches this stage, could DIFS review it? What are the benefits and limits of that route, and could you help with the filing or urgency letter if appropriate?”

Why I’m asking: I want to understand the right appeal route without losing a filing deadline.

Who does what

The three parts, side by side. The agency decides; nobody on this page does.

You

File within the deadline and send the denial letters.

Your social worker

The plan must supply the file.

The care team

The oncologist writes the letter that carries the urgent route.

Who decides
An independent review organisation appointed through Michigan DIFS.
Ask your social worker
“The plan has issued a final denial. Can we file a state external review, and can the doctor write a letter for the urgent route?”

How to apply

First step: Keep the final denial letter, then file form FIS 0018 or the online form. Help is on 877-999-6442.

  1. Ask the hospital social worker to check the final denial and your plan type with DIFS.
  2. If you choose review, submit FIS 0018 or the online form with denial letters and the medical support.
  3. For urgent treatment, ask the oncologist about the required urgency letter and the expedited plan appeal.

Official application / program page ↗

Where it starts: File form FIS 0018 or the online form.

What to gather

  • The plan’s final denial letter
  • The internal appeal paperwork
  • A letter from the treating doctor

How long: The current DIFS form lists 127 days after receipt of the final denial. The urgent route has a 10-day contact condition and 72-hour decision. DIFS confirms which clock applies to the notice.

What a yes looks like

A reviewer’s decision overturning the denial, which the insurer must follow.

What a no looks like, and the next move

Ask which medical standard the reviewer used, and whether new evidence can be submitted.

Watch out

  • DIFS’s current instructions use receipt of the final denial for the filing clock. The social worker can confirm the exact deadline with DIFS; keeping the notice and envelope helps resolve date questions.
  • For the urgent route, DIFS requires an expedited internal appeal to have been requested, contact within 10 days after receipt of the adverse determination, a physician’s urgency statement and treatment not yet delivered. The family need not wait for the internal expedited appeal to finish before asking DIFS about urgent external review.
  • DIFS confirms the route for public, school, municipal or church plans.

Dates that change this

2023-12-01: FIS 0018 excludes nongovernmental self-funded plans and specified products. DIFS confirms its authority over the actual plan and the applicable receipt-based filing deadline.

The numbers and the rules

The arcane layer, kept on purpose. Checked September 11, 2026.

What it is worth

A binding outside review for eligible disputes. The current DIFS form lists a 127-day receipt-based filing window; urgent cases have separate entry rules and a 72-hour decision.

  • $127 — Days to file after receiving the final denial
  • $72 — Urgent external review decision time
  • $10 — Days to reach the regulator on the urgent route

Legal protection: An independent reviewer’s decision binds the insurer · Help on 877-999-6442

What it costs the family: None to file.

The eligibility facts, as published

Plans
DIFS confirms whether the particular plan and dispute fall within its review authority. FIS 0018 excludes nongovernmental self-funded plans and specified limited-benefit products; it does not answer every state, school, municipal or church plan question. The current form gives 127 days after receipt of the final denial. Your social worker can confirm the operative deadline with DIFS rather than rely on the last possible day.
Procedure
normally after the plan’s internal process, with a waiver where the plan did not follow it

The trap: For the urgent route, DIFS requires an expedited internal appeal to have been requested, contact within 10 days after receipt of the adverse determination, a physician’s urgency statement and treatment not yet delivered. The family need not wait for the internal expedited appeal to finish before asking DIFS about urgent external review.
