A health insurance denial can look final when the first page says a claim will not be paid. Keep reading. The notice should tell you why the insurer made that decision and how to dispute it. Those instructions may lead to an appeal with the insurer, an independent external review, or a state office. The first task is to identify which route the letter actually describes.

Read the denial before choosing a route

Start with the decision itself. Which service or claim was denied? Does the letter say the insurer refused payment, or that coverage ended? What reason does it give? Then find the date of the decision and every page labeled appeal, review, or dispute. According to HealthCare.gov, an insurer must explain why it denied a health claim or ended coverage and tell you how to challenge the decision.

Compare the reason with the instructions. A sentence explaining why a claim was denied is not the same as a sentence telling you where to send an appeal. If either part is hard to find or too vague to understand, note that gap. Keep the full letter, including pages that appear to contain only standard notices. ProPublica has reported that external review instructions can be buried in denial paperwork.

This guide focuses on health plan claim and coverage decisions. A decision about eligibility to enroll through the Health Insurance Marketplace or qualification for premium tax credits has a separate appeal process. An auto or property insurance denial also calls for its own policy terms and state guidance, rather than the health appeal steps below.

Ask the insurer for an internal appeal

An internal appeal asks the insurer to take another look at its own decision. HealthCare.gov describes this as a full and fair review. Read the letter for where to send the request, what information to include, and the deadline that applies. The sources here do not establish one filing deadline for every plan, so do not treat a missing deadline on the first page as permission to wait.

Frame the request around the decision you received. Identify the claim, quote or summarize the stated reason, and explain what you believe the insurer should reconsider. If you have records that bear on that reason, the letter or plan instructions should help you determine how to submit them. Keep copies of the request, supporting documents, and any response. A dated record makes it easier to tell which question has been answered and which remains open.

Is a delay likely to harm your health? Say so plainly when you contact the insurer and check the instructions for an urgent appeal. HealthCare.gov says an insurer must speed up an internal appeal when the case is urgent. Urgency changes the timing of review; it does not guarantee that the insurer will reverse its decision.

Look for an independent external review

An external review moves the disputed health plan decision outside the insurance company. An independent third party reviews it, so the insurer no longer has the final say about whether to pay the claim, according to HealthCare.gov. That is a different step from asking the same insurer to reconsider during an internal appeal.

Find the external review section in your denial or appeal paperwork. Who does it name as the contact? Does it direct you to a state insurance department or another review process? What does it say you must send, and by when? In one case reported by ProPublica, a denial letter included state insurance department instructions, and a doctor working for a third-party review company later overturned the denial. That case illustrates how review can work, not how any other claim will end.

Do not assume the rules for someone else’s plan apply to yours. The sources used here do not settle which state’s rules govern a particular plan, the cost of a review, or what happens if an insurer does not follow a review decision. Use the written instructions for your plan and confirm unclear requirements with the office identified in them.

Know what a state regulator can address

A state insurance department may be the contact named in health insurance external review instructions. It may also receive complaints about insurance practices. Before sending anything, separate two questions: Are you asking for an independent decision on your claim, or are you reporting a problem with how the insurer handled the process? The answer matters because a general complaint should not be assumed to replace an appeal or preserve an appeal deadline.

If the letter names a state office, use that office’s published instructions to check where the request belongs. If it does not, look for your state insurance department’s guidance and ask which process applies to the kind of health plan decision you received. Describe the problem in specific terms: the decision date, the claim number, the reason given, the instructions you received, and any response to an appeal. Keep a copy of what you submit.

A state consumer protection office is a different contact. USAGov’s directory lists those offices for complaints against businesses and concerns about scams or fraud. Check the office’s role before filing. Reporting a business practice may help an agency understand a problem, but it does not, by itself, decide an individual claim.

Check what the paperwork leaves unanswered

Before the next deadline passes, make a short list of unanswered questions. Did the insurer give a specific reason and a way to dispute it? Have you found the complete internal appeal instructions? Does the letter explain external review, including the correct destination for your request? If the situation is urgent, have you made that clear and checked the urgent-review instructions?

Also ask what a state complaint would accomplish in your situation. The sources for this article do not give a universal method for filing with an insurance regulator or describe what follows every complaint. They do not establish universal appeal deadlines, either. Confirm those details in the insurer’s written notice and with the office responsible for the process, rather than relying on a general description of your rights.

A denial letter is a record of one decision, not necessarily the end of the process. Read it for the reason, compare that reason with the route for disputing it, and keep the pages together.
