Health insurance or Medicaid said no in Montana? Deadlines and free help

In Montana, your health plan is regulated by Montana Commissioner of Securities and Insurance (CSI), Office of the Montana State Auditor, if it is a state-regulated plan.

Montana runs its own independent review of denials: External Review. You generally have 120 days to ask for it.

External review means a doctor or reviewer outside your plan decides again. Internal appeal means your plan looks at its own decision again.

Which kind of coverage was denied? The plan type decides which rules and deadlines apply.

Insurance I bought or got through work

Your state insurance rules may apply. First appeal to your plan, then ask for an outside review.

My employer pays claims itself (self-funded)

Federal rules apply, and most state insurance laws do not. Free help comes from the U.S. Department of Labor.

Montana Medicaid

You ask the state for a fair hearing. In a Medicaid health plan, you usually appeal to the plan first.

Marketplace (HealthCare.gov) decision

A decision about whether you can buy a plan or get financial help is appealed to the Marketplace.

How to tell which agency regulates your plan

If you bought insurance yourself or get it from an employer that does business only in Montana, contact the CSI. If your job-based coverage is from a self-insured employer (often a large company or one with locations in several states), contact the U.S. Department of Labor's Employee Benefits Security Administration.

Step 1: Appeal to your plan in Montana

What it is called: Grievance (internal grievance review)

Montana law follows the federal timelines: the insurer must decide within 30 days for care you have not received yet, 60 days for care already received, and 72 hours for an expedited review. Your insurer's grievance papers must tell you that you can contact the Commissioner's office for help at any time, with its phone number and address.

Urgent care in Montana: faster decisions

Outside review

You can ask for expedited external review if the normal time could seriously jeopardize your life or health or your ability to regain maximum function, or if the denial concerns an admission, continued stay or service after emergency care and you have not been discharged. The reviewer must decide as fast as your condition requires and no later than 72 hours after receiving the request. Expedited review is not available for care you already received.

Law: Mont. Code Ann. 33-32-404, 33-32-405, 33-32-410, 33-32-411, 33-32-412, 33-32-415, 33-32-422

Medicaid

The state manual offers an expedited hearing to households that will leave Montana before a decision would normally be made. No separate health-urgency rule is stated in the manual; federal rules require an expedited hearing when the normal timeline could seriously jeopardize your life, health or ability to regain maximum function.

Law: ARM 37.5.307
