Six months in Minnesota, and two different agencies

Work out which agency is yours before anything else

Minnesota is one of a small number of states where external review does not have a single address. The division is by plan type, and getting it wrong costs time you may not have at the end of a six-month window.

• Enrolled in an HMO — the external appeal goes to the Minnesota Department of Health.
• Any other health insurance plan — the external review goes through the Minnesota Department of Commerce.
• If the plan is a self-funded employer plan, neither applies: that is the federal route.

Six months, not four

The request must be made within six months of the date of the adverse determination, and the intake screens for exactly that: whether it has been six months or less since the decision being appealed. It is one of the more generous windows in the country, but it is still a window, and it runs from the plan's decision rather than from the date you decide to act.

Finish the plan's own appeal first

In most cases the internal appeal with the plan has to be complete before the external one can start. For an HMO enrollee that means filing the complaint through the HMO and letting it run its course; only then does the Department of Health take the external appeal. Building the internal appeal properly therefore does double duty — it is both the first chance to win and the record the external reviewer will read.

How to file

1. 1

   Complete the plan-level appeal

   File the complaint or appeal with the HMO or insurer and let the internal process finish, except where the situation is urgent.

2. 2

   Complete the external appeal form

   The enrollee — or anyone acting on the enrollee's behalf, including a treating provider with authorisation — completes the state's External Appeal form.

3. 3

   Send it to the right agency

   Department of Health for HMO enrollees; Department of Commerce for other health plans.

4. 4

   Flag urgency if waiting is unsafe

   If a 45-day wait could harm the patient, request the expedited 72-hour appeal rather than the standard track.

What it costs and how long it takes

• Applying for external review is free — and not by policy but by statute: Minn. Stat. 62Q.73 provides that the cost of the external review must be borne by the health plan company.
• A standard external appeal may take up to 45 days.
• An expedited appeal is decided within 72 hours where the standard wait could harm the patient.
• Anyone acting on the enrollee's behalf may bring the appeal, not only the enrollee.

Prior authorization under Chapter 62M

Minnesota has two provisions in Minn. Stat. ch. 62M that change the arithmetic for a practice, and both are now in force:

• An authorization for treatment of a chronic health condition does not expire unless the standard of treatment for that condition changes — effective January 1, 2026. A chronic condition is one expected to last a year or more that either needs ongoing medical attention or limits activities of daily living.
• Utilization review organizations must run a prior-authorization exemption process, and the threshold is percentile-based: a provider or group at the 70th percentile or above for authorization rates is exempt. The commissioner adopted the rules by January 1, 2025 and administration was required by January 1, 2026.
• Requests must be accepted without unreasonable delay by telephone, fax, voicemail or an electronic mechanism, 24 hours a day, seven days a week.

For Minnesota practices

The six-month window is generous enough that the real risk in Minnesota is not the deadline but the address. A practice working denials across several payers should record, alongside each denial, whether the product is an HMO — because that single fact decides whether the file goes to Health or to Commerce, and a misdirected appeal comes back as lost weeks rather than as a decision.

A Minnesota-licensed physician in your specialty

Minnesota does not let a nonclinical reviewer close out a clinical denial. Minn. Stat. 62M.09 requires a physician to review and make the adverse determination in every case where the utilization review organization has concluded that a clinical adverse determination is appropriate, and that physician must hold a current unrestricted Minnesota license and be of the same or a similar specialty as a provider who typically treats or manages the condition.

On appeal the requirement tightens further. Under Minn. Stat. 62M.06 the organization must ensure a physician of the same or a similar specialty is reasonably available to review the case, and its physician consultants must be board certified by the American Board of Medical Specialties or the American Osteopathic Association. The enrollee may review the information relied on, present evidence and testimony, and hold continued coverage while the appeal is pending.
