The process

From denial letter
to appeal in 48 hours.

Insurance companies count on you giving up. Most people do — 60% of denied claims are never appealed. We turn your denial into a professional, policy-specific appeal that speaks the language insurers actually respond to.

Upload your documents

Send us your denial letter, Explanation of Benefits (EOB), or surprise medical bill. A phone photo is perfectly fine. We accept PDFs, images, and forwarded emails.

We find the leverage

Our team reads your denial reason codes, cross-references your plan's specific coverage language, and identifies the exact policy provisions that apply to your case. Most denials have at least one technical error or an applicable regulation the insurer didn't account for.

You get a ready-to-send appeal

Within 48 hours, you receive a complete, professionally written appeal letter — with the right citations, the right tone for your insurer, and clear instructions for exactly where and how to submit it.

We follow up if needed

If your first appeal is denied again, we help you escalate — to internal review level 2, external independent review, or your state insurance commissioner. You have more options than you think, and we know all of them.

Why ClaimBolt

Built for the letter you
don't know how to fight.

⚖️

We speak insurance fluently

Denial reason codes, CPT codes, ICD-10 classifications, plan coverage exclusions — we read it so you don't have to. Your appeal will reference the exact policy provisions and regulations that matter.

⚡

Appeals have deadlines — we move fast

Most insurers allow only 30–180 days to appeal a denial. Miss the window and your right to appeal is gone. We deliver in 48 hours so you always have time to act.

🎯

We know what actually works

Different insurers respond to different approaches. We track what language, what documentation, and what escalation paths get denials reversed — and apply that knowledge to every appeal we write.

🔁

We don't stop at the first letter

If the first appeal is denied, there are more options — internal appeals level 2, external independent review, state insurance commissioner complaints. We know every escalation path and walk you through each one.

Common questions

Things people ask
before getting started.

We handle insurance claim denials (medical, dental, vision, prescription), surprise out-of-network bills, prior authorization denials, claims denied as "not medically necessary," and itemized hospital bills with suspected coding errors. If you received a bill or denial letter that doesn't feel right, send it to us and we'll tell you whether we can help — for free.
At minimum, your denial letter or Explanation of Benefits (EOB). If you have the original itemized bill, your insurance card details, and any written communications from your provider or insurer, those help too. A clear photo on your phone works — you don't need to scan anything.
You pay nothing upfront. We write and support your appeal. If the denial is reversed or your bill is reduced, we collect 20% of the amount you recover. If we don't win anything, you owe us nothing. We only make money when you do — which means we only take cases we believe in.
No one can guarantee an insurance reversal — anyone who tells you otherwise is lying. What we guarantee is a professionally written, policy-accurate appeal that gives you the best possible chance. Nationally, 40–60% of appeals succeed when they're actually filed. The problem is that 60% of people never file one at all.
Most insurers have multiple levels of internal appeal. After that, you have the right to an independent external review — required by law in most states — where a third party reviews your case independently of your insurer. If that fails, you can file a complaint with your state insurance commissioner. We'll guide you through every step.
Everything you send us is treated as strictly confidential. We do not share your documents with your insurer, your provider, or any third party. We use your information solely to prepare your appeal. We do not sell your data.
No, ClaimBolt is not a law firm and this is not legal advice. We are a professional appeal writing and review service. For complex legal disputes involving healthcare, we recommend consulting a healthcare attorney. That said, the vast majority of denial appeals are administrative — not legal — matters, and do not require an attorney to resolve.
