How to file an external review in Colorado
In Colorado, external review is run by the state itself, not the federal HHS process. After your insurer issues its final internal appeal denial, you submit a written external review request, including the Division of Insurance request form and a consent form, to your insurance company, which forwards it to the Colorado Division of Insurance (DORA). The Division assigns an Independent Review Organization whose decision is binding on the carrier. You generally have four months from the final internal denial to request review. Standard reviews are decided as soon as possible and no later than 45 days; expedited review for urgent situations is decided within 72 hours. The process is free to you, with no filing fee. Authority is C.R.S. 10-16-113.5.
Colorado appeal questions
How do I request an external review in Colorado?
Send a written external review request to your insurance company after it issues the final denial of your internal appeal. Include the completed external review request form specified by the Colorado Division of Insurance plus a signed consent form allowing release of relevant health records. The insurer then forwards your request to the Division, which assigns an independent reviewer; you do not pay a filing fee. The Division of Insurance Consumer Services Team can walk you through the steps and confirm the current form.
What is the deadline to file for external review in Colorado?
You generally have four months from the date of your insurer's final internal appeal denial to request an independent external review. Missing that window can forfeit your right to review, so do not wait once the final denial arrives. If your situation is medically urgent, you can ask for an expedited external review and, in some cases, skip the standard internal appeal levels.
Does Colorado external review cost anything, and is the decision binding?
There is no fee to you for an external review in Colorado; the cost is borne by the insurer and the state's program. The Independent Review Organization's decision is binding on the insurance company, so if the reviewer overturns the denial, the carrier must cover the service or treatment. Standard reviews are decided within 45 days, and expedited urgent reviews within 72 hours.
What if my plan is a self-funded employer plan (ERISA)?
Colorado's external review through the Division of Insurance applies to state-regulated plans, such as individual and most fully insured group coverage. If your employer self-funds its plan, it is governed by federal ERISA rules, and your external review typically follows the plan's process or the federal HHS-administered review rather than Colorado's. Check your plan documents or denial letter, which should state which external review process applies to you.
