External Review Health Insurance Denial: Your Second Chance

External review health insurance denial: how independent review works

An internal appeal takes place within the health plan. External review brings in an independent review organization or reviewer through the applicable state or federal process. The reviewer considers the eligible coverage dispute and supporting information under that process's rules.

HealthCare.gov explains that, in the external review process it describes, the insurer must accept the independent reviewer's decision. That makes external review meaningful, but it does not mean a denial will be overturned. The reviewer can uphold the insurer's decision too.

External review is not the same as negotiating a provider's bill, filing a lawsuit, or appealing Marketplace eligibility. Those issues can require different procedures and different sources of help.

External review health insurance denial: which claims may qualify?

HealthCare.gov identifies denials involving medical judgment, decisions that treatment is experimental or investigational, and certain cancellations of coverage based on alleged false or incomplete application information. The exact eligibility rules depend on the applicable process.

A disagreement about medical necessity may be a candidate for external review. A simple billing typo or a dispute about an expressly excluded benefit may follow a different path. Do not assume a claim qualifies only because its dollar amount is large or an internal appeal was denied.

Ask the plan or review administrator: "Is this decision eligible for external review? If not, please explain the reason and the other review options available." Your notice should be the starting point, but a state insurance department or Consumer Assistance Program may help you identify the correct route.

State and federal routes are not all the same

CMS describes state external review systems and federal processes for coverage subject to the relevant rules. Your plan type and state can determine which organization handles the request. Some private-sector workplace plans follow different arrangements from individual insurance policies.

The Affordable Care Act's appeal protections described by CMS apply to non-grandfathered plans. Other plans and programs can have different protections. Medicare, Medicaid, federal employee coverage, and government employee plans have their own rules and should not be assumed to follow a standard commercial-insurance external review route.

Use the organization and contact details in your notice. If they are missing or confusing, ask your plan administrator or insurance regulator where to file. Sending records to the wrong office can waste valuable time.

Check the deadline before gathering more records

Deadlines vary by plan. Check the denial letter for the exact dates. Read the final internal appeal decision as well as any separate external review instructions. Confirm what event starts the filing window and whether the administrator must receive the request by the deadline.

HealthCare.gov describes a four-month request window for the external review process it outlines. Treat that as guidance about that process, not a universal deadline. Your plan, state, or coverage program may have different instructions.

Do not assume that asking for clarification or preparing a packet pauses the clock. If the deadline is near, contact the review administrator immediately about the filing requirements and whether additional supporting records can be submitted later.

What belongs in an external review packet?

Follow the administrator's form and instructions. A well-organized submission commonly starts with the request form, the original denial, and the final internal appeal decision. Include relevant supporting records and any clinician's explanation that addresses the medical issue in dispute.

Make an index naming each item. Label the evidence consistently and point to the pages that matter. The goal is to help the reviewer find the documented facts, not to bury the issue under unrelated paperwork.

Check whether a signature, representative authorization, or other permission is required. Keep a complete copy and proof of delivery. Ask for confirmation that the request is complete and eligible for review, and note the reference number and expected decision date.

If a process charges a filing fee, ask the administrator about the amount and any applicable limits or waivers. A document-preparation service's fee is separate from any review administrator's fee. You can use the review process yourself without buying a preparation service.

What if the care cannot wait?

Some cases qualify for expedited external review when the applicable urgency requirements are met. HealthCare.gov describes circumstances in which urgent internal and external review may be requested at the same time. Ask your care team and plan immediately which urgent process applies.

Do not assume that a regular review will happen quickly enough for a time-sensitive treatment decision. A document organizer cannot decide whether care is medically urgent, provide treatment, or extend deadlines. Seek immediate medical help for an emergency.

After the review decision

Read the decision in full and keep it with your claim records. If the denial is overturned, follow up with the insurer about implementing the decision and with the provider about any updated bill. If it is upheld, ask the relevant assistance program or a qualified adviser about any remaining options for your coverage and circumstances.

What the external-review statistics can and cannot show

KFF's analysis of 2024 HealthCare.gov plan data found that insurers denied 19% of in-network claims and fewer than 1% of denied in-network claims were internally appealed. These are figures for qualified health plans on HealthCare.gov, not for every health insurer.

KFF reported at least 5,881 external appeals, but could not calculate their outcome rate because small reported values were suppressed. Its 66% figure describes internal appeals where insurers upheld the denial, not external reviews won by patients. There is no verified two-thirds external-review success rate in that analysis, and no statistic can promise the outcome of your case.

Need help preparing the documents?

For denied claims of $3,500 or more, Cura's paid Denial Appeal Packet service organizes your records into a focused letter, deadline sheet, indexed evidence appendix, and submission and follow-up checklist. The internal appeal packet is $349. If it goes to external review, the price is $599. You submit the packet yourself. We are not lawyers and this is not legal advice.

A person reviews your case, and you keep every dollar you win back.
