Oregon draws your reviewer at random — and gives you 180 days

How Oregon's external review works

Oregon's external review is handled by the Division of Financial Regulation (DFR). It covers four kinds of dispute: medical necessity, experimental or investigational treatment, the appropriate setting or level of care, and prescription-drug formulary exceptions. The defining Oregon feature is neutrality by design — the DFR randomly assigns your case to an independent review organization it contracts with, so the health plan has no hand in choosing the reviewer.

• Eligible disputes: medical necessity, experimental/investigational, appropriate level of care, and drug-formulary exceptions.
• The DFR randomly assigns the IRO — the plan cannot select it.
• The IRO's decision binds the insurer; an overturn means the plan must cover the service.
• No Surprises Act payment disputes are handled through the separate federal process, not this one.

The 180-day deadline

You have 180 calendar days after receiving the plan's final adverse determination to request external review — a notably longer window than the federal four-month standard. The request is routed through the plan, which by law must forward it to the DFR for IRO assignment (within two days for standard cases, immediately for expedited ones).

How to file

1. 1

   Finish the internal appeal

   Complete the plan's internal appeal first, except in urgent situations, which can move immediately.

2. 2

   Request external review

   Submit the referral request; the insurer is required to forward it to the Division of Financial Regulation ([email protected]) for assignment.

3. 3

   The DFR assigns an IRO at random

   The Division emails you the name and contact of the randomly chosen independent review organization.

4. 4

   The IRO decides on the record

   The reviewer evaluates the denial and the medical documentation; the decision binds the plan.

How fast — and who pays

• Standard external review: decided within 30 calendar days.
• Expedited (urgent): within 3 calendar days — for emergencies, admissions/continued stays, or when a provider certifies the normal timeline would seriously jeopardize the patient.
• The IRO's cost is borne by the insurer, not you.
• The IRO's decision is binding on the plan.

What Oregon's published outcomes show

Oregon is one of the few states that publishes its external-review results. The DFR posts an IRO case-detail report as a downloadable spreadsheet, refreshed quarterly on a rolling four-year window, so the record is checkable rather than anecdotal. Four consecutive years land in the same band:

• 2024 — 555 cases decided, about 34% overturned or partially overturned.
• 2023 — 499 cases, about 36% overturned or partially overturned.
• 2022 — 498 cases, about 37%.
• 2021 — 326 cases, about 32%.

A prior authorization that binds the insurer

Oregon puts unusual weight behind an approval already in hand. Under ORS 743B.420, a prior authorization for benefit coverage or medical necessity binds the insurer when it was obtained within 60 days before the service; an approval based on eligibility binds when obtained within 5 business days before the service. The exception is misrepresentation. If a claim you pre-authorised comes back denied after the fact, that statute — not a general fairness argument — is the thing to cite.

The step-therapy override, and the five grounds that carry it

ORS 743B.602 requires every insurer to run a clear, accessible step-therapy exception process, and it enumerates the grounds. An override must be granted when any one of them is documented:

• The required drug is contraindicated for this patient.
• It is expected to be ineffective given the patient's clinical history.
• The patient already tried it — or another drug in the same class — and it failed.
• The patient is currently stable on the drug the plan is trying to replace.
• The required drug is otherwise not in the patient's best medical interest.

Two business days, either to decide or to say what's missing

Oregon runs a short clock. ORS 743B.423 requires an insurer to issue a determination on a request for coverage of a non-emergency treatment, drug, device or diagnostic or laboratory test subject to utilization review within a reasonable period appropriate to the medical circumstances, and no later than two business days after receiving the request.

If the insurer needs more to decide, it does not simply go quiet. Within the same two business days it must notify the enrollee and the provider in writing of exactly what additional information is required. Oregon also requires qualified personnel to be available for same-day telephone response to inquiries about certification of a continued length of stay.
