A denial letter is not the end. It's the start of your appeal.
Every plan has to tell you why a claim was denied and how to challenge it. Your appeal turns on four things: the exact reason on your EOB, your internal appeal deadline, your right to an independent external review, and the evidence that speaks to that reason. We organize all four into one packet, built from your own denial.
A denied claim has more than one door. Your packet keeps all three straight.
An appeal is not one letter into a void. It moves through a few defined stages, each decided by a different party. Here is how they stack, and who decides each one.
Read the denial
The denial reason is the whole game: not medically necessary, prior authorization missing, out of network, experimental, or a coding error. Your packet is built around the exact reason printed on your letter.
Internal appeal
Your first formal appeal goes back to the insurer, in writing, by the deadline on your notice. Miss it and you can lose the right, so your packet works the calendar backward from your own date.
External review
If the internal appeal is denied, most plans give you an independent external review by someone who does not work for your insurer. Your packet includes the request template and where to send it.
One packet, built around your denial reason, plan type, and deadline.
Your denial details organized into a personalized internal appeal letter, an external review request template, an evidence checklist, a deadline calendar, and a call log, built from your own answers.

The letter, the evidence, the deadlines, and a record of every call. In one place.
Your packet assembles the same materials a well-prepared appeal needs, so you can focus on your case instead of chasing paperwork.
Straight with you about what a packet can and cannot do.
We never promise a denial will be overturned. No honest service can. What we do is put a complete, on-time, well-organized appeal in front of the people who decide.
Every deadline and requirement points back to your own denial letter, your plan documents, or your state, never a number we invented to look more helpful.
DenialCrusher is a document-preparation service, not a law firm, insurer, or doctor. You can appeal for free on your own; we make it faster and better organized.
Every packet is backed by a 30-day money-back guarantee. DenialCrusher is a new service, so we do not show customer reviews yet; the cards above describe how the packet is built, not testimonials.
Every kind of denial, and the appeal it needs.
Procedures & surgery
Denied as not medically necessary or missing prior authorization.
Medications
Denied for step therapy, formulary, or prior authorization reasons.
Imaging & tests
MRIs, CTs, and diagnostic tests denied as not medically necessary.
Therapy, DME & out-of-network
Ongoing visits, equipment, and out-of-network care disputes.
Whether an insurer reverses a decision depends on your plan, your facts, and your insurer. Any site that guarantees an outcome, a success rate, or a dollar amount is not being straight with you. What we can do is make sure your appeal is complete, on time, and built around the exact reason you were denied.
DenialCrusher is an independent document-preparation service, not a law firm, insurance company, or medical provider. You always have the right to appeal at no cost on your own.
Your exact internal appeal deadline.
The denial notice your insurer mailed you, and your plan documents.
“Enter the deadline printed on your denial letter,” then builds your calendar backward from that date, never a date we guessed.

Frequently asked questions
Will DenialCrusher guarantee my appeal succeeds?
No outcome is ever promised. DenialCrusher is a document-organization and preparation service, not a law firm, insurance company, or licensed insurance advisor. The Insurance Appeal Letter Packet organizes your own denial details into a personalized internal appeal letter, an evidence checklist, a deadline calendar, and a call log, so you can present the strongest version of your own case. You always have the right to appeal at no cost on your own.
What types of denials does DenialCrusher cover?
The Appeal Letter Packet covers the most common denial reasons: not medically necessary, experimental or investigational, out of network, prior authorization missing, coding or billing errors, and benefit not covered. It works with employer (ERISA), marketplace/ACA, Medicare Advantage, and Medicaid managed care plans. Your own denial letter and plan documents always control the specifics of your case.
Is DenialCrusher HIPAA compliant?
Yes. All data is encrypted in transit and at rest. Your information is used only to generate your appeal packet and is never sold or shared with third parties. You can delete your data at any time.
Can I use this for Medicare or Medicaid denials?
Yes. Medicare Advantage and Medicaid managed care are both plan type options during intake, and your letter and evidence checklist adapt to your denial reason regardless of plan type. Traditional Medicare and state fee-for-service Medicaid appeals follow their own specific process; your denial notice will state the process that applies to you.
How long does it take to get my appeal packet?
Most buyers complete the guided intake in about five minutes. Your personalized appeal packet, including your internal appeal letter, evidence checklist, deadline calendar, and call log, is ready immediately after checkout.
What if the packet isn't what I needed?
Every purchase of the Insurance Appeal Letter Packet is covered by a 30-day money-back guarantee. Email support@denialcrusher.com within 30 days of your purchase and we will refund it in full, no forms, no hoops. See our refund policy for details.
