Missouri Nurse Injury Lawyer

Cynthia Hennessey - Workers' Comp and Personal Injury Lawyer

I was a nurse before I was a lawyer

I’m Cynthia Hennessey. I became a registered nurse in 1985 and worked at SSM Health Cardinal Glennon Children’s Hospital and at BJC before I ever set foot in a courtroom. I started my legal career defending insurance companies and employers, which taught me exactly how they decide what an injured worker’s claim is worth. I have practiced law for 35 years, and since leaving insurance defense I have represented only injured workers and accident victims in Missouri and Illinois.

When a nurse calls me, I don’t need the chart translated. I know what a two-person transfer done by one person looks like at 3 a.m. I know what “patient tolerated well” can hide. And I know how the insurance company will read your records, because I used to read them for the other side.

Nurses make terrible patients. I say that with love.

I know because I was one. We triage everybody on the unit except ourselves. We finish the shift, pick up the extra one because the floor is short, and tell ourselves the back will settle down by Monday. Nobody wants to be the nurse who “can’t handle it,” and nobody wants to be the one the manager starts watching.

So most of the nurses who call me have waited. The pain was there for weeks before anyone ordered an MRI. The incident report was never filed, or it was filed with four words in it. None of that makes a claim hopeless, but it does make it harder, and it is exactly the kind of gap an insurance company looks for first.

If you remember one thing from this page, make it this: Missouri generally requires you to give your employer written notice of a work injury within 30 days. Report it immediately if you can, keep a copy, and do not assume that a late report automatically ends your claim, exceptions may apply. Say what you were actually doing. “Lifting a patient” is a start. “Boosting a 260-pound patient up in bed by myself because the lift team was tied up” is a record.

The injuries that end nursing careers

Most strains heal. This page is about the ones that don’t. The injuries that end nursing careers are rarely dramatic. They come from the work itself: transfers, repositioning, catching a patient who starts to go down, pushing beds, and twelve hours on your feet.

How you were injured matters. But once compensability is established, one of the most important questions is what the injury has done to your ability to work and live. A permanent restriction of “no lifting over 20 pounds” sounds modest on paper. On a med-surg floor, where your patients weigh ten times that, it is the end of bedside nursing. My job is to make sure the insurance company understands the difference.

If a patient hurt you

Violence from patients is its own kind of injury, and it deserves its own fight. Concussions, physical injuries, and PTSD resulting from a patient assault may be covered by Missouri workers’ compensation. Psychological-injury claims have special proof requirements, so they should be evaluated carefully. I have a separate page on nurses injured by patient assault that explains how these claims are proven and why insurers fight them so hard. For the legal detail, see our research on workplace violence against nurses in Missouri.

What a nurse’s eye catches in your file

Every lawyer can read a medical record. Very few have written them. Here is some of what I look for when a nurse’s file lands on my desk.

  • The first note. “Pain 3/10,” charted while you were trying to finish your shift, does not mean the injury was minor. It means you are a nurse.
  • The word “degenerative.” Almost every adult spine shows some wear on an MRI. Insurers use it to call your injury pre-existing, and it rarely means what they want it to mean. I explain why in what degenerative changes on your MRI actually mean.
  • The restrictions. Vague restrictions quietly push nurses back to the floor too soon. Specific ones protect you. I work with your treating doctors so the paperwork matches what your body can actually do.
  • The nurse case manager. The insurer may assign a nurse to your claim. They are often kind, and often good nurses. They also work for the insurance company, and what they write goes to the adjuster.

Because I spent years on the other side, I also know the standard defense of a nurse’s claim: it was pre-existing, it was degenerative, and anyway she can always go work at a desk. That last one needs its own section.

“You can always do telehealth”

This is the argument insurers love when a bedside nurse can no longer lift. You have a license and a degree, the reasoning goes, so you can do phone triage, utilization review or case management from home. Therefore you are not really disabled.

Sometimes a nurse genuinely is ready for a new role, and I will tell you so. Often, though, those jobs need experience and certifications you don’t have, hours at a screen your injury won’t allow, and they pay far less than you earned at the bedside. Whether you can actually compete for work in the open labor market is the heart of a permanent total disability claim, and it is where many nurse claims are won or lost. I build that evidence carefully, with vocational experts when the case calls for it, instead of letting the insurer simply assume the answer.

Two nurses whose careers ended at work

E.G., registered nurse, Mercy Medical Center, St. Louis County

E.G. hurt her low back lifting a large patient. It looked like a routine lifting injury. It became an L4-L5 herniated disc, multiple lumbar surgeries, a spinal fusion, and finally a spinal cord stimulator and a morphine pain pump. She never returned to nursing or to any other work.

Her employer denied and delayed her care, so we went back to court again and again to get her treatment and pain management, and ultimately a full-time non-medical assistant to help with housekeeping, meals and heavy household work. We obtained lifetime workers’ compensation benefits to replace her lost income, and helped her secure Social Security Disability so her support came as close as possible to what she earned before she was hurt.

M.T., operating room nurse, Phelps County Medical Center

M.T. was 49 when she injured her neck and shoulder lifting a patient. She needed surgery on both, and her permanent restrictions ended her nursing career. We took her case to trial and won permanent total disability benefits, paid weekly for life, plus lifetime medical care for both injuries. We also helped her obtain Social Security Disability and Medicare.

Past results do not guarantee a similar outcome. Every case depends on its own facts.

What your claim can cover in Missouri

  • Medical care: all reasonable and necessary treatment for the injury, including surgery, therapy and pain management, with no co-pays.
  • Temporary total disability: Generally two-thirds of your average weekly wage, subject to the state maximum, while the injury leaves you temporarily unable to work.
  • Permanent disability: permanent partial disability for lasting impairment, or permanent total disability if you cannot return to any work.
  • Future medical care: for implanted devices, repeat surgeries and long-term pain management, this can matter more than any lump sum.

That last point is where I see the most harm done. A settlement that closes future medical can look generous and still leave a nurse paying for her own care for decades. Knowing what your body will need in ten years is a nursing question before it is a legal one.

For every nurse, not only RNs

I represent registered nurses, LPNs, CNAs, patient care techs, surgical techs and nurse practitioners, at hospitals, nursing homes, rehab facilities and home health agencies. Honestly, CNAs often have it hardest: more lifting, less help, and less of a paycheck to fall back on. The law protects all of you the same way.

I represent nurses in St. Louis and across Missouri, and in Illinois hospitals across the river. You can read more about me and my background, or simply call. You took care of everyone else. Let me take care of this.

Still charting through the pain? Let’s talk before it gets worse.

Questions nurses ask me

Will a workers’ comp claim put my nursing license at risk?

Filing a workers’ compensation claim does not, by itself, put your nursing license at risk. The claim concerns an injury you suffered at work; it is not a complaint about your nursing practice, and requesting benefits is not professional misconduct.

If your injury or your medications ever affect whether you can practice safely, that is a separate question, and one worth talking through with me early and privately.

The insurance company assigned a nurse case manager who comes to my appointments. Do I have to talk to her?

Be polite, be factual, and remember who they work for. A nurse case manager reports to the insurance company, and what you say in the waiting room can end up in the adjuster’s file. You can ask for time alone with your doctor. If the case manager seems to be steering your care, or you are not sure what to share, call me before the next appointment.

My back got worse over months of 12-hour shifts. There was no single injury. Is that covered?

It can be. Missouri covers injuries that develop from repetitive work, not only sudden accidents, as long as your work was the prevailing factor in causing the condition. These claims need careful documentation of your duties, your symptoms and the timeline, which is exactly where understanding the job helps. Report it as soon as you connect the pain to your work.

My hospital offered me light duty as a sitter or on the phones. Do I have to take it?

Often yes, if the job truly fits your doctor’s restrictions, because refusing suitable light duty can stop your temporary disability checks. But it has to actually fit. A sitter assignment that turns into helping with transfers is not light duty. Tell me what you are being asked to do, and we will check it against what your doctor wrote.

Employee health wants me to use my own insurance. Is that okay?

If your injury happened at work, workers’ compensation should pay for your care, with no deductibles or co-pays. Running it through your own health insurance can muddy the record and leave you with bills later. Report it as a work injury, even if employee health sees you first.

I’m afraid I’ll be pushed out if I file. What can I do?

Missouri law prohibits an employer from firing or discriminating against you for exercising your workers’ compensation rights. That does not mean it never happens. If you are being pressured to resign, please don’t sign anything before we talk. I have written more about what happens if you are fired while you have a claim.

I live in Missouri but work at an Illinois hospital. Which state’s law applies?

It depends on where you were hired, where you work and where you were hurt, and sometimes more than one state is available. Missouri and Illinois calculate benefits differently, so the choice can matter. I am licensed in both states and can tell you which applies and which serves you better. You can see how Illinois calculates benefits on our Illinois benefit rates page.

A patient hurt me. Is that a workers’ comp claim?

Often, yes. A physical injury caused by a patient while you are doing your job is generally covered, whatever the patient’s condition or intent. PTSD and other psychological injuries have special proof requirements, and insurers fight them hard. My page on nurses injured by patient assault covers them in detail.
