Denied Workers’ Comp Claim Lawyer in St. Louis

Cynthia Hennessey - Workers' Comp and Personal Injury Lawyer

Cynthia Hennessey, Denied Claim Lawyer in St. Louis

Cynthia M. Hennessey is a registered nurse, a Missouri and Illinois workers’ compensation attorney, and a former insurance defense lawyer. She spent the early part of her career on the other side of these files, and she has spent the 35 years since representing the people receiving the letters.

A denial is a medical argument written in legal language. Someone has to read the records it rests on and say what they actually show. That is the part of this work she was trained for twice.

What a Denied Workers' Comp Claim Means in Missouri

A denial letter is not a ruling. It is one company’s decision, written by an adjuster, and it usually rests on a medical opinion the insurer arranged and paid for. Nothing about it is final.

In Missouri the claim moves forward when a Claim for Compensation is filed with the Division of Workers’ Compensation. From that point the question stops being what the insurer believes and starts being what the evidence shows, in front of an Administrative Law Judge who does not work for either side.

That distinction matters, because most people read the letter as the end of the matter. It is closer to the beginning of it.

Denied Is Not the Same as Disputed

People use the word denied for several different problems. They have different answers, so it is worth separating them before deciding what to do next.

  • The claim is denied outright. The insurer says the injury is not work related, or not compensable at all, and pays nothing.
  • Treatment is refused or stalled. The claim is open, but the surgery, injection, MRI or specialist referral your doctor recommended is not authorized, or it sits in “pending review” with nobody saying yes or no.
  • Payments stop. Temporary total disability ends while you are still off work and still under restrictions.
  • The rating is disputed. The claim is accepted, but the insurer’s doctor assigns a percentage of disability that bears no relation to what your body can now do.
  • Course and scope is contested. Nobody argues you were hurt. They argue you were not working when it happened. Parking lots, breaks, travel between locations and company events all produce this fight.
  • Permanent total disability is denied. The insurer accepts the injury but not that it ended your working life. The largest disputes in Missouri workers’ compensation sit here.

The first three are urgent, because bills and rent do not wait. The last three are where the value of a serious claim is usually won or lost.

Why Workers’ Comp Claims Get Denied in St. Louis and Across Missouri

After 35 years the arguments are familiar. Almost all of them are medical arguments wearing legal clothes, which is why they are answered with medical evidence rather than with indignation.

The most common are that the condition is pre-existing or degenerative and would have happened anyway, that the injury was not reported quickly enough, that the medical records do not support what you describe, that you were not in the course of your employment, or that you are capable of light or sedentary work and therefore not disabled at all.

Each of those is answerable. What each of them requires is somebody who can open the imaging reports, the operative notes and the restrictions and explain, in the language the file is written in, why the argument does not hold.

Read the Denial Letter Before You Answer It

A denial letter has to give a reason, and that reason is more useful than it looks. It tells you which argument the insurer thinks it can win, and so where the evidence needs to go. The mistake most people make is to answer everything at once. Answer the reason they gave.

  • “Not work related” or “pre-existing.” The fight is medical causation. Missouri asks whether work was the prevailing factor in your current condition and your need for treatment, and that question is answered with a physician’s opinion, not with a longer letter to the adjuster.
  • “Reported late.” Missouri expects written notice to the employer within 30 days of the injury. Missing it gives the insurer an argument, it does not automatically end the claim. The answer is proof of when and how you told people: texts, emails, and the names of the supervisors and co-workers who knew.
  • “No medical support.” Usually a gap in treatment, or records that never connect the condition to work. Sometimes the problem is not your injury, it is your file.
  • “Inconsistencies.” The recorded statement says one thing, the ER intake note says another, and a social media post suggests a third. Innocent differences are still the raw material of denials, and they are answered by going back through the records line by line.
  • “Not an employee” or “no coverage.” Independent contractor labels and arguments that the employer was not required to carry workers’ compensation. How you were actually paid, supervised and scheduled matters more than what the paperwork called you.

“A denial is the insurance company’s opening position, not the final verdict.”
Cynthia Hennessey, RN, JD

The IME Is Where Most Missouri Denials Are Built

If your claim has been denied, or your treatment has been cut off, there is very often an independent medical examination behind it. The name is misleading. The examination is arranged and paid for by the employer or the insurer, it is not treatment, and the doctor’s job is to produce an opinion rather than to make you better.

An unfavorable report is not the end of a claim. It is one opinion, and it can be answered with another. What it should not be is something you walk into unprepared, without knowing what is being assessed or how briefly it will be done. If you want the detail before you go, we have written it up here: Workers’ Comp 101: The Independent Medical Evaluation.

Reading the File the Denial Was Written From

Cynthia trained as a registered nurse before she trained as a lawyer, and she began her legal career defending insurance carriers. Both halves matter on a denied claim.

The nursing background means the medical record is not something that has to be handed to an expert before anyone can say what it means. Failed conservative care, surgical history, imaging, permanent restrictions and what a person can realistically still do for a living are the things that decide these cases, and they are read directly.

The insurance defense background means the denial itself is not a surprise. She knows how carriers evaluate a file, which arguments they run when the medicine is thin, and what they do when a claim starts costing more than they set aside for it.

What You Can Do With Your Own Medical Records

Denials that say “not work related” or “pre-existing” live or die on the medical records, and those records were written by busy clinicians who were never thinking about a legal case. A note that says “chronic back pain” and leaves out the fall. An intake form with the wrong box ticked. A history that garbles what you actually said. Cynthia has spent enough years on both sides of a chart to know how often that happens, and how much it costs later.

  • Ask for complete copies of your records and read them, not just the discharge summary.
  • If something is wrong, ask the provider to correct it through their formal amendment process. Stick to facts, not arguments.
  • At every visit, say how and when it happened: “This started when I fell from the loading dock on March 3rd.” Every time, even when it feels repetitive.
  • Do not panic about “degenerative changes” on your imaging. Most adult spines show them. The legal question is whether work was the prevailing factor in your current condition, and we have explained what degenerative changes on your MRI actually mean in a separate piece.

Bring us the denial letter and the medical records. We will tell you what they actually say.

The Six Arguments Behind Most Missouri Denials

It is pre-existing

The most common denial in Missouri. Degenerative changes appear on almost every adult spine. Their presence does not mean the work injury did not cause the disability.

You reported it too late

Reporting delays are common with injuries that build over time, and with workers who tried to keep going. Late notice is a defense, not an automatic bar.

The records do not support it

Usually this means the records were read quickly. Symptoms that are documented across multiple visits tell a different story than a single intake note.

You were not at work

Parking lots, breaks, travel between job sites and employer events. Course and scope is contested far more often than most injured workers expect.

You can do light duty

A job that exists on paper is not the same as employment you can be hired for. Vocational evidence decides this, not the insurer's assumption.

The IME says you are fine

One examination, arranged by the other side, lasting a few minutes. It is one opinion in a file, and it can be answered.

Denied and Disputed Claims We Have Resolved

$600,000+

Back pay plus $807.48 a week for life, awarded on appeal after the claim was denied at hearing

$450,000

Settled on the morning of trial after the employer denied the claim on course and scope

Lifetime benefits

Won at trial for an officer the employer and insurer accused of faking his injuries

Three Denied Claims, and How They Ended

A judge denied the claim. The Commission reversed it.

A UPS delivery driver with a 35 year career injured his left knee at work. On its own it looked like a simple knee case, and the Administrative Law Judge denied benefits. The argument we took to appeal was that the knee could not be looked at on its own: he already carried a prior knee condition with surgery, a documented disc herniation and an earlier work-related ankle injury, and he had kept working through each of them. Together they made him unemployable.

The Labor and Industrial Relations Commission reversed, found the pre-existing disabilities were hindrances to employment, and held the Missouri Second Injury Fund responsible for permanent total disability. He received over $600,000 in back pay and $807.48 a week for life.

The employer said he was faking.

A police officer developed severe psychological injury after a suicide by cop incident. He was 36. The employer and the insurer took the position that he was malingering, which is the standard defense when the injury does not appear on imaging.

We tried the case in the Missouri Workers’ Compensation Court in Springfield and proved the injuries. He was awarded lifetime workers’ compensation benefits. Psychological claims are denied more often than physical ones, and they are won the same way, by documenting the condition properly rather than arguing about it.

The employer said she was not at work yet.

An HR manager slipped on unseen black ice in her employer’s parking lot one winter morning, fell backwards onto the back of her head and suffered a concussion and a significant neck injury. She never returned to work. The employer denied the workers’ compensation claim, arguing she was not within the course and scope of her employment while walking into the building.

The claim settled for $450,000 on the morning of trial. Because a third party was also responsible for the condition of the lot, we pursued the snow removal contractor and the property manager alongside it. The head injury side of this case is covered in more detail on our brain injury page.

Prior results do not guarantee a similar outcome. Every case is different and is judged on its own facts. The same applies to the client accounts on this page, including any reference to an improved offer.

First Things to Do After a Workers’ Comp Denial

  1. Keep treating. A gap in treatment hurts your health and your case at the same time. If you have health insurance, use it while the dispute is pending, and keep every bill and explanation of benefits.
  2. Write down your filing deadline. Missouri’s time limits are set out below. Whatever your date turns out to be, it is the most important date in your case. Do not drift toward it.
  3. Gather the file. The denial letter, every medical record, your written injury report and proof you sent it, witness names, pay records, every letter and email from the insurer, and your own notes.
  4. Get quieter, not louder. A pending dispute means the insurer is paying more attention, not less. Stay off social media, do not talk about the case with co-workers, and do not guess in any recorded statement. “I don’t know” is a complete answer. In serious claims, insurers also use surveillance, and what the camera doesn’t show explains why one clip is not the whole story.
  5. Have the denial read by someone who knows what it rests on. By the time a letter goes out, the insurer, its adjusters and its reviewing doctors have committed to a position. It is worth knowing where you stand before you answer it.

What Happens After a Denial in Missouri

  1. The Claim for Compensation is filed with the Division of Workers’ Compensation. This is what moves the dispute out of the insurer’s hands, and the employer and insurer have to file an answer to it.
  2. Mediation and pre-hearing conferences. The Division holds settings before an Administrative Law Judge to narrow the issues and look for a resolution short of trial. A good number of denied claims resolve here. Insurers that meet organized medical evidence and a represented worker have a way of rediscovering their flexibility.
  3. The medical evidence is built. Treating physicians, records, depositions and, where necessary, an independent evaluation of our own to answer the insurer’s.
  4. A hearing is requested before an Administrative Law Judge. Where treatment or temporary disability payments have been stopped, a hardship hearing brings that dispute forward rather than waiting for the case to conclude. When the case is ready, a final hearing decides compensability and benefits.
  5. The award can be appealed. An Application for Review goes to the Labor and Industrial Relations Commission within twenty days of the award, and from the Commission to the Missouri Court of Appeals. The UPS case above was won at this stage.

Missouri generally allows two years from the date of injury, or from the last payment made on the claim, to file. Where the employer never filed a report of injury with the Division, that becomes three years. Deadlines are the one part of this that cannot be repaired later, so the sooner a denied claim is looked at, the more of it is still available.

When the Claim Is Open but Treatment Is Refused or Stalled

There is a particular kind of limbo in Missouri workers’ compensation, and if you are in it, you know it. The doctor the insurance company chose says you need an MRI, more therapy, a specialist or an operation, and then nothing happens. Nobody says no. Nobody says yes. The clinic is waiting on authorization, the adjuster says it is pending review, and the calendar keeps turning.

“A treatment plan on hold is not neutral. Bodies do not pause while paperwork does.”
Cynthia Hennessey, RN, JD

Who Picks Your Doctor in a Missouri Workers’ Comp Case?

Under section 287.140 of the Missouri statutes, the employer must provide the medical care reasonably required to cure and relieve the effects of the injury, and with that comes the right to choose the authorized treating doctor. It surprises almost everyone. It is also not the whole story.

  • Authorized treatment is paid for by the employer or insurer, without your health plan’s copays or deductibles.
  • You can see your own doctor as well, but generally at your own expense. What you should not do is quietly swap your doctor for theirs and stop attending authorized care. That reads as non-compliance and hands the insurer a reason to cut off benefits.
  • In an emergency, get care first. Tell the employer promptly afterwards and keep a record of what happened.
  • The authorized doctor’s views on causation, maximum medical improvement and your disability rating are opinions, not findings. They can be answered with an evaluation from a physician of your own choosing, and when one is needed the firm advances the cost.

Employer Selects, Doctor Recommends, Insurer Authorizes

That chain explains most stalls. The authorized doctor examines you and recommends the next step, but recommending is not ordering. The request goes to the insurer, which decides whether to pay for it, often after a review by a nurse, or by a physician who has never laid eyes on you. When treatment stalls it is almost always at that third link, which means the person holding things up is usually not the person who examined you.

“Pending review” describes the insurer’s internal paperwork. It is not a ruling, it does not come from anyone with authority over your claim, and it does not put your rights on hold.

“Calling the adjuster repeatedly is not the same thing as having a legal remedy.”
Cynthia Hennessey, RN, JD

If the adjuster has simply gone quiet, start with what to do when the adjuster won’t respond.

Put the Recommendation on Paper

Stalled care is won or lost on documentation, and this is where having a nurse on the file earns its keep. In her hospital years Cynthia watched plenty of verbal “let’s get some imaging” comments evaporate because they never made it into the chart. A recommendation that is not in the record is invisible to everyone who reviews the file later. A written order sitting unanswered is exactly the kind of paper a judge can weigh.

  • MRI. Ask the office for a copy of the order or referral note. Without imaging there is no firm diagnosis, and without a diagnosis nothing behind it moves. More on what happens if you need an MRI.
  • Physical therapy. When visits stop being scheduled mid-course, ask the clinic to note in your chart that the reason is authorization, and write it in your own log too. A gap documented as the insurer’s doing reads very differently from one that looks like yours.
  • Specialist referral. The employer and insurer arrange specialists as well, so you usually cannot just book the orthopedic surgeon yourself. Get the referral in writing and record every request for a date. “Their doctor recommended it and they would not provide it” is a powerful sentence, if you can prove it.
  • Surgery. Highest stakes, longest waits. Second opinions and records reviews can run for months. We cover both ends: what happens if surgery is recommended and what happens after surgery.

The Pattern With Delayed Surgery

The version Cynthia sees most often goes like this. The surgeon recommends the operation in early spring. By midsummer the worker is still calling the adjuster, unable to work, watching the season pass through the kitchen window. When the file finally lands on a desk with a hearing request attached, the authorization that could not be found for four months turns up quickly. The operation was never the obstacle. The absence of pressure was.

The Hardship Hearing: Missouri’s Answer to Stalled Care

Missouri saw this problem coming. When needed medical treatment or temporary total disability is being denied or delayed, a hardship hearing puts the dispute in front of an Administrative Law Judge without waiting out the ordinary pace of the claim. It is an evidentiary hearing, available under section 287.203 and the Division’s rule at 8 CSR 50-2.010(13), when a worker is not at maximum medical improvement, needs treatment, or is owed temporary total disability. We explain how a Missouri hardship hearing works in more detail.

The raw material of a hardship setting is the paper trail above: the authorized doctor’s written recommendation, a dated log of requests that went nowhere, and a file showing the insurer sat on its own physician’s advice. If the insurer has refused the care outright, start with what to do when the insurer won’t authorize treatment. The same route applies when the weekly checks stop while you are still off work, which we cover in what to do if your checks are late or stop.

“When workman’s comp told me I had hit the maximum amount they could pay, I called Hennessee and guess what… treatment was not longer denied! Don’t be jerked around, call Hennessee you will be pleased!”
Shannon Arthur-Baker, Rolla, MO, Google review

If Your Claim Was Denied in Illinois

The firm is licensed in Illinois as well as Missouri, and a good deal of our work comes from the Metro East. The process is similar in shape and different in its detail. Illinois claims go to the Workers’ Compensation Commission rather than the Division, and the filing deadline is generally three years from the date of injury or two years from the last compensation payment, whichever is later. If you were hurt in Illinois and denied, do not apply Missouri’s deadlines to your claim.

Talking to a Denied Claim Lawyer in St. Louis

There is no fee to have a denial looked at, and no fee unless we recover for you. What is useful to bring is the denial letter itself, anything the insurer has sent about an independent medical examination, and the names of the doctors who have treated you.

We are not a volume practice, and we will tell you plainly if a claim does not need a lawyer. If it does, you will be dealing with an attorney who has read the file.

Clients Whose Claims Were Refused, Delayed or Undervalued

Denied Workers’ Comp Claims: Common Questions

My workers’ comp claim was denied in Missouri. What should I do first?

Keep the denial letter and note the date on it. Keep treating, and keep the records. Then have someone read the letter against your medical file, because the stated reason for a denial and the real reason are often not the same thing. What you should not do is stop treatment, because a gap in the records is the single most useful thing you can hand the other side.

How long do I have to challenge a denied claim in Missouri?

Missouri generally allows two years from the date of injury, or from the last payment made on your claim, to file a Claim for Compensation. If your employer never filed a report of injury with the Division, that period is generally three years. Illinois deadlines are different. Because the limits are strict and the facts decide which one applies, get the dates confirmed early rather than assuming.

The insurance company’s doctor says I am fine. Does that end my claim?

No. An independent medical examination is arranged and paid for by the employer or the insurer, and it produces an opinion, not a finding. That opinion can be answered with a competing evaluation and with your own treating records. Several of the results on this page began with a report saying the injury was not what the worker said it was.

My claim is open but they will not approve my surgery. Is that a denial?

It is a dispute over medical treatment rather than a denial of the whole claim, and it is handled differently. In Missouri, disputed treatment can be taken to a hardship hearing before an Administrative Law Judge rather than waiting for the case to resolve. Get the surgeon’s recommendation in writing and keep a dated record of every request. It is worth acting quickly, because a delayed surgery frequently becomes a worse outcome, and the delay itself becomes part of the case.

Who chooses my doctor in a Missouri workers’ comp case, and can I see my own?

The employer and its insurer choose the authorized treating doctor and pay for that care. You can see your own doctor too, generally at your own expense, but keep attending authorized treatment while you do. The authorized doctor’s opinions can be answered with an evaluation from a physician of your own choosing, and treatment that the authorized doctor recommends but the insurer will not provide can be taken to a hearing.

The insurer says my treatment is “pending review.” Is that a denial?

Not formally, but it can do the same damage. Pending review is the insurer’s internal process, not a ruling by anyone with authority over your claim. If a written recommendation from the authorized doctor has gone unanswered for weeks, that delay can be taken to a hardship hearing, and the longer it runs, the more it belongs in the evidence.

They stopped my weekly payments while I am still off work. Can they do that?

Insurers do stop temporary total disability payments, often on the strength of an examination or a release to light duty that does not reflect your actual restrictions. Under section 287.203 they have to tell you they are stopping and why, and you have the right to ask for a hearing on it rather than simply absorbing the decision. If your payments have stopped and your doctor has not released you, that is a matter to raise straight away.

They say I was not at work when I was hurt. What now?

Course and scope arguments are common, and they are frequently wrong. Injuries in employer parking lots, during breaks, while traveling between work locations and at employer-run events are often compensable in Missouri even though the worker was not at a desk or a machine at the time. The facts decide it, and the facts usually need collecting before the employer’s version sets.

What does it cost to have a denied claim reviewed?

Nothing. The review is free and there is no fee unless we recover for you. If your claim is straightforward and does not need representation, we will say so.
