Idaho lets a stalled internal appeal be treated as finished

The request goes to the state, not the insurer

Idaho routes external review through the Department of Insurance. The written request is submitted to the Department within, but not later than, 120 days from the date of the final denial by the insurance company, and it is the Department that sends the case on to the reviewing organization. That is a different posture from states where the request is lodged with the carrier and forwarded.

The 35-day exit from a stalled grievance

Exhaustion of the internal grievance process is the general rule. But Idaho attaches a limit to the insurer's silence: a covered person may request external review if they have not received a written decision on the grievance from the health carrier within 35 days following the date the grievance was filed. An unanswered appeal stops being a reason to wait.

42 days, and 72 hours when it is urgent

Idaho's standard decision clock is 42 days from the reviewing organization's receipt of the request from the Department — slightly tighter than the 45 days most states use. On the expedited track under Idaho Code 41-5909, available where the requested service meets the definition of an urgent care request, the organization must decide within 72 hours and notify the covered person, the health carrier and the Department of the result.

• Request filed with the Department: within 120 days of the final denial.
• Standard decision: 42 days after the organization receives the request.
• Expedited decision: 72 hours, for a pre-service or concurrent urgent care request.
• Deemed exhaustion: no written grievance decision within 35 days of filing.

Who is allowed to review

An independent review organization in Idaho must be accredited by URAC, a nationally recognized private accrediting entity, and approved by the Idaho Department of Insurance. Accreditation is the state's proxy for reviewer competence and independence, and it is the reason the decision is given binding force rather than advisory weight.

Which denials qualify

The Act gives a right to review where the denial rests on the health carrier's requirements for medical necessity, appropriateness, health care setting, level of care or effectiveness, or where the service was determined to be investigational. That is the clinical-judgement family. A denial that turns purely on a written exclusion is a contract argument and belongs on a different track.

• Medical necessity.
• Appropriateness of the service.
• Health care setting.
• Level of care.
• Effectiveness of the treatment.
• A determination that the service is investigational.

The decision binds the carrier

The reviewing organization's determination is binding on the health insurance company. That is what makes the effort proportionate: unlike an internal appeal, where the same organisation that denied the claim decides whether it was right, the external stage produces an outcome the insurer must honour.

For Idaho practices

Track two dates per case, not one. The final denial date starts the 120 days. The internal grievance filing date starts the 35-day clock that lets you escalate when the carrier does not answer at all — which, in practice, is the more common problem. And note the 42-day decision window when you set patient expectations; it is three days shorter than the figure most national guidance quotes.
