Escalation paths beyond your insurer: commissioners, ombudsmen, and external review

When your insurer's internal appeals are exhausted, you still have options: independent external review, state regulators, the Department of Labor for self-funded employer plans, and state consumer assistance programs or health insurance advocates. Who does what, and when each applies.

Updated Sep 26, 2026Evidence-backed

A final "no" on your internal appeal usually isn't the end. Depending on your plan, an independent reviewer, a state regulator, federal officials or a patient ombudsman may be able to step in.

Why these options exist

Insurers have an obvious conflict of interest when they review their own denials, so the system adds a layer of outside oversight. These routes matter most once you've been through your plan's internal appeal process, which our guides on what a successful appeal campaign looks like and how to write an appeal letter cover.

Your options after a final denial

External (independent) review

Most health plans must offer an external review once internal appeals are exhausted. You have 4 months from the final denial notice to ask for it in writing. The review is done by an accredited independent review organization (IRO) that must have no conflict of interest that would affect its independence. Your plan pays the IRO's fee, but it doesn't get to choose which IRO takes your case (DOL Technical Release 2011-02 (external link)). The insurer is legally required to accept the reviewer's decision (healthcare.gov (external link)). Few people use it. In HealthCare.gov marketplace plans in 2024, fewer than 1% of denied in-network claims were appealed at all, and marketplace enrollees filed at least 5,881 external appeals, about 4% of the internal appeals insurers upheld (KFF, March 2026 (external link)).

Your state insurance commissioner or department of insurance

Every state has an insurance regulator that oversees fully insured health plans. Our guide on state coverage mandates explains the fully insured vs. self-funded distinction, which matters here too. These offices take consumer complaints for free. They can investigate unfair claim delays or denials and violations of state insurance law, and if they find the insurer acted improperly they can require it to fix the problem (NAIC (external link)). What they generally can't do is force coverage of a benefit your plan excludes.

The Department of Labor (for self-funded employer plans)

Private employers' self-funded plans are regulated under ERISA, the federal benefits law, and state insurance law mostly doesn't reach them. That puts them under the Department of Labor, not your state insurance commissioner. If your employer plan denies a claim improperly (as opposed to excluding a benefit category, which is generally permitted), this is the more relevant federal avenue.

The Department of Labor's Employee Benefits Security Administration (EBSA) takes complaints and enforces the claims-procedure rules plans must follow. One of those rules gives you at least 180 days after a denial to file your internal appeal (DOL (external link)). Its benefits advisors can contact your plan for you, and EBSA says that when a complaint is valid it seeks "informal dispute resolution" (DOL (external link)). EBSA can push the plan, but it doesn't issue a binding decision on your claim the way an external reviewer does.

Two exceptions are easy to miss. Plans run by governments (state, county, city) and by churches for their employees aren't covered by ERISA at all, so different rules apply to them (DOL (external link)). And external review for a self-funded ERISA plan normally runs under the federal rules, through accredited independent review organizations the plan contracts with and rotates cases among. Federal guidance also lets a self-funded plan voluntarily use a state's external review process instead, so ask your plan which one applies to you (DOL Technical Release 2011-02 (external link)).

Consumer assistance programs and ombudsmen

Some states have a Consumer Assistance Program, started with federal grants, that helps people file complaints and appeals against health plans (CMS (external link)). Some states also run a health insurance advocate or ombudsman office. Connecticut's Office of the Healthcare Advocate, for example, is a state agency that "advocates for consumers when their benefits are denied" (CT OHA (external link)). If you're struggling with a complex denial on your own, ask your state insurance department whether either kind of help is available where you live.

A rough order of operations

  1. Internal appeal (first, and second level if available)
  2. External independent review
  3. State insurance commissioner complaint (fully insured plans) or Department of Labor (self-funded plans)
  4. Help from a consumer assistance program, state health insurance advocate or advocacy organization, which can run in parallel with any of the above

Common questions

Questions people often ask about this topic.

  • What can I do after my insurer denies my final internal appeal?

    You usually still have options. Most health plans must offer an external review by an independent review organization once internal appeals are exhausted. Beyond that there are state insurance regulators, federal Department of Labor oversight for self-funded plans, and consumer assistance programs or state health insurance advocates. These outside checks exist because insurers have a conflict of interest in reviewing their own denials.

  • What is external review, and is the decision binding?

    External review is done by an accredited independent review organization that must have no conflict of interest affecting its independence. Your plan pays for the review but can't pick which organization handles your case, and the insurer is legally required to accept the decision. You have 4 months from the final denial notice to request it. Few people use it: in HealthCare.gov marketplace plans in 2024, external appeals amounted to about 4% of the internal appeals insurers upheld.

  • When should I contact my state insurance commissioner?

    Every state has an insurance regulator that oversees fully insured health plans and takes consumer complaints for free. It can investigate unfair claim delays or denials, and if it finds the insurer acted improperly it can require the insurer to fix the problem. It generally can't force coverage of a benefit your plan explicitly excludes.

  • What if my employer plan is self-funded?

    A private employer's self-funded plan is regulated under ERISA, the federal benefits law, so the Department of Labor oversees it instead of your state insurance commissioner. If the plan denies a claim improperly (as opposed to excluding a benefit category, which is generally permitted), the Department of Labor's EBSA can take your complaint and try to resolve it informally with the plan. External review for these plans normally runs under federal rules through independent review organizations the plan contracts with, though a plan can choose to use a state's process instead. Government and church plans aren't covered by ERISA.

  • In what order should I try these escalation options?

    A rough order: internal appeal first (including a second level if your plan offers one), then external independent review, then a state insurance commissioner complaint for fully insured plans or the Department of Labor for self-funded plans. Help from a consumer assistance program, state health insurance advocate or advocacy organization can run in parallel with any of these.
