Workers' Comp Claim Denied? Here's Exactly What to Do

You open the mail and there it is: your workers' comp claim was denied.

If you just got that letter, take a breath. A denial is not the end. It's closer to the beginning of a process that the insurance carrier was hoping you wouldn't fight. Depending on the state, somewhere between 6% and 12% of workers' comp claims are denied initially. Of those that get appealed, a meaningful share get reversed — especially when the denial was procedural.

This is the actual playbook. What to do today, this week, and this month, in order.

Step One: Read the Denial Letter Carefully

Every denial letter has to state the reason. That sentence is the most important thing in your file, because how you fight back depends entirely on why they said no.

You're looking for one of five patterns. "Injury is not compensable" means the carrier is saying your injury didn't happen at work or isn't covered by workers' comp. "Failure to provide timely notice" means they're arguing you told your employer too late. "Injury pre-existing or not work-related" means they're pointing at a prior MRI or doctor visit and saying your current problem started before your job. "Missed the filing deadline" means the statute of limitations passed before you filed. "Insufficient medical evidence" means they're saying your doctor's notes don't prove what you claim.

Each of these has a different counter-move. Most of them are beatable. Three are pure paperwork problems that proper documentation often solves on appeal.

Step Two: Mark the Appeal Deadline on Your Calendar Right Now

Before you do anything else, find the deadline and write it somewhere you'll see every day.

The number you're looking for is usually buried in a paragraph near the end of the letter. It ranges wildly by state. Pennsylvania gives you 20 days. Florida gives you 30. California gives you 90 for some denial types. A handful of situations have deadlines as short as 10 days.

Miss the deadline and the denial becomes final. There's no "but I didn't know" exception in most states. Insurance carriers count on injured workers being overwhelmed and letting the clock run out; it's not an accident that denial letters are confusing to read. Set three reminders: one at halfway to the deadline, one a week before, one three days before.

Step Three: Gather Your Evidence Packet

You need to assemble the story that contradicts their denial. The pile looks roughly the same in every case:

The original First Report of Injury (your employer should have filed one — request a copy). The accident report from your workplace. A written timeline of what happened, when you reported it, and to whom. Names and contact info for every witness. All medical records related to the injury. Any photos of the accident scene or your injuries. Text messages, emails, or voicemails where you told anyone (supervisor, HR, coworker, spouse) that you'd been hurt at work. Your pay stubs for the 13 weeks before the injury.

The specific missing piece that matters most depends on why you were denied. If it's "late notice," you need proof of when you first reported the injury. An email to your supervisor dated two days after the accident can single-handedly overturn a late-notice denial. If it's "pre-existing condition," you need medical records showing that the current problem is different in kind or severity from anything that existed before. If it's "insufficient medical evidence," you need a stronger note from your treating doctor specifically linking the work activity to the injury.

Step Four: File the Appeal (Sometimes Called a Hearing Request or Petition for Benefits)

Every state has a form. It's usually downloadable from the state workers' comp board's website. In many states you can file it online. It costs nothing.

What you're formally asking for varies by state, but it's always something like: "A judge should review the carrier's denial." That kicks the case out of the insurance company's control and into a neutral forum. The carrier's adjuster now has to justify their decision to someone who doesn't work for the insurance company.

After you file, you'll get a hearing date. The wait is typically 60 to 180 days, depending on your state's docket backlog. California and New York are the slowest. Some smaller states set hearings within 30 days.

Step Five: Decide About an Attorney Before the Hearing

Every state's workers' comp board tracks outcomes by representation status, and the pattern is remarkably consistent across 50 states: people who appeal with an attorney win around 62% of the time. People who appeal alone win around 37%.

That gap is enormous. It reflects real work attorneys do — they know what evidence the judges actually care about, they know the local judges, they know how to prepare witnesses, they know which carrier defenses tend to fold at mediation and which go to hearing. They also know when to just pick up the phone and call the carrier's attorney before anything formal happens.

Workers' comp attorneys work on contingency. You pay nothing upfront. If you win, the fee is a percentage of the award — capped by state law at around 15-25%. If you lose, you owe nothing. For denials involving surgery, permanent impairment, or disputed medical causation, the math almost always favors getting representation. The cases where you might reasonably handle it alone are clear-cut procedural errors, like a late-filed First Report that you can easily prove you sent on time.

What Happens at the Hearing

A workers' comp hearing is not what movies make it look like. It's a small, informal room with an administrative law judge (the title varies — in some states "Workers' Comp Judge," in others "Industrial Commissioner"). There's no jury. The rules of evidence are relaxed. You might have 30 minutes to present your side. Witnesses are limited. Medical evidence is usually in the form of written reports rather than live doctor testimony.

The judge is there to decide whether the carrier's denial was correct or not. Their ruling is binding on both sides but appealable. Most hearings produce a written ruling 30-90 days later.

The single best thing you can do to prepare: rehearse telling your story in under 5 minutes. Date of injury, what you were doing, what happened, when and to whom you reported it, what treatment you got, what your current limitations are. Clear, chronological, specific. Don't editorialize, don't complain about the carrier, don't speculate. Facts, dates, documents.

If the Denial Was for "Pre-Existing Condition"

This is the most common fight-worthy denial. Insurance carriers pull your medical records and find any prior doctor visit, MRI, chiropractor appointment, or gym injury that involved the same body part. Then they argue your current problem is just a continuation of that.

Workers' comp law in every state covers aggravations of pre-existing conditions. If you had a bad back before your lifting injury, and then your lifting injury made it materially worse (more pain, a new MRI finding, inability to do work you could do before), the aggravation is compensable. The carrier has to prove the work injury contributed nothing new, which is often a hard sell to a judge.

Your treating doctor's note matters most here. You want a clear, one-paragraph statement from them saying: the work activity on [date] caused or materially aggravated [specific condition], and the current symptoms would not exist (or would be meaningfully milder) without it. Doctors sometimes need to be asked specifically for this kind of statement — they tend to write in medical shorthand that doesn't satisfy workers' comp judges.

Denied vs Disputed Claims — Not the Same Thing

Worth clarifying: "denied" means the carrier rejected your claim entirely. "Disputed" means they're challenging specific elements — the scope of treatment, the extent of disability, the body parts covered — while accepting the claim overall.

Disputed claims are usually easier to resolve than outright denials. Full denials get a hearing. Disputes often settle in mediation or informally between attorneys before a hearing is even scheduled.

If you're not sure which you got, call the state workers' comp board. Their intake staff will read the paperwork with you and tell you what category your situation falls in. That call is free.

The Bottom Line

A denied workers' comp claim is a project, not a verdict. The carrier bet you wouldn't fight. Most injured workers don't, which is why denials are common in the first place.

Get the denial letter. Mark the deadline. Gather your evidence. File the appeal. Call a workers' comp attorney for a free consultation — at a minimum, they'll tell you whether your specific facts are worth taking to hearing or whether something about the denial makes it genuinely hard to beat.

Your case gets harder the longer you wait. Start today.
