For US health insurance denials and medical bills

A denial letter is not the final word.

Upload your denial letter or EOB. We explain it in plain English and find your appeal route and deadline, for free. If you want, we then prepare the appeal packet that you send yourself.

Denials are common. Appeals are rare, often because the process is confusing.

How it works

Three steps. You stay in charge of every one.

Free

Step 1

Understand the denial

We read your letter or EOB and tell you why the claim was denied, what the codes mean, your plan type and your deadline.

$49 per case

Step 2

Build your appeal packet

A letter for your plan's appeal route, request letters for your claim file and your doctor, and a checklist of the evidence to attach.

Step 3

You review and send it

Edit anything, download one PDF, and send it to your plan the way your letter says. We remind you before each deadline, if you turn reminders on.

The full walkthrough

The parts most letter writers skip

A good letter matters less than sending it the right way, on time, with the right evidence. That is where we spend our effort.

The right route for your plan

Employer and marketplace plans follow different rules. We match the steps to your plan type and cite the rule we used.

Your deadline, worked out and on your calendar

We work out your deadline from the date on your letter, add it to your calendar and email you before it.

An evidence checklist

What to gather for your denial reason, what you already have, and what to ask your doctor or plan for.

Request letters, ready to send

Ask your plan for your claim file and the criteria it used. Ask your doctor for a letter of medical necessity.

A letter you can edit

Every sentence is yours to change. We point out anything still missing before you download.

One PDF to send

Letter, requests and a cover sheet in order, with where to send it for the largest insurers.

Add the bill audit, $79 total

Check the bill against what your plan says you owe

We compare your itemized bill with your EOB, line by line. We flag duplicates, charges your plan says you do not owe, and bills that may break the No Surprises Act. Then we draft the dispute letters.

  • Duplicate and unbundled charges
  • Amounts above your EOB "you may owe" line
  • Surprise out-of-network bills and good-faith estimate checks
  • A screen for the hospital's financial assistance program

What we are, and what we are not

AppealHaven is a document-preparation tool. It is not a law firm, an insurer or a medical provider, and it does not give legal or medical advice. You decide what to send, and you send it.

  • Explain your letter in plain English
  • Find the route and deadline your plan's rules set
  • Draft letters you review, edit and send
  • Act as your lawyer or representative
  • Tell you which treatment you need
  • Promise an outcome. No one honestly can.

Free help is out there too

Many states run a free consumer assistance program for insurance problems. Medicare and Medicaid members can get free one-on-one help. We point you to these in every result, whether you pay us or not.

Common questions

Do I need an account?

Not to decode a letter. You need an account to start a case, so your documents and deadlines are saved. You sign in with your email and a 6-digit code we send you. There is no password.

Do you send the appeal for me?

No. You send it. We prepare one PDF and show you where to send it for UnitedHealthcare, Aetna and Cigna. For other plans, use the address or form named in your denial letter.

We do not mail, fax, call or write to your plan for you, and we are not your representative.

Is this legal advice?

No. AppealHaven is a document-preparation and information tool. It is not a law firm, it is not your lawyer or representative, and it is not a substitute for a lawyer.

You may want a lawyer if your case goes to court, for example a lawsuit against a self-funded employer plan after the appeals are done. Legal aid offices help people with low incomes for free.

Can you promise my appeal will work?

No. Your plan, or an independent reviewer, makes the decision. No one can honestly promise an outcome, and we do not.

All questions and answers
