For a work injury or accident in Glen Carbon, IL, care is at our clinic next to Lambert Airport. It is about thirty-five minutes away via I-270 west. Illinois lets you choose the treating physician. It also compensates the aggravation of a condition that was not causing symptoms before the injury.
The argument that ends more Glen Carbon claims than any other is not that the injury did not happen. It is that it was already there.
We are a medical practice, not a law firm. The statutory position here is summarized from the Illinois Workers’ Compensation Commission. Your own claim belongs with your attorney.
Can workers’ comp deny a claim because of a pre-existing condition?
Degenerative disc disease, arthritic change, an old sports injury — almost everyone over thirty has something on imaging. When a claim is disputed, those findings get pulled out as the real cause. The injury is then recast as coincidence.
Illinois law does not work that way. An employer takes the worker as found. If work aggravated or accelerated a condition that was not causing symptoms before, that aggravation is compensable. The eggshell principle explains the doctrine.
How do you prove a work injury aggravated a pre-existing condition?
It takes a before and an after, shown clinically, not just claimed. Function before the injury, function after, and a mechanism that plausibly links the two. All of it written down at the time, not rebuilt at a hearing.
Proving exacerbation lays out what that record looks like. It is largely the same record that produces good treatment.
Can I choose my own doctor for workers’ comp in Illinois?
Yes. The record showing that before-and-after is written by whichever physician examines you. Illinois lets you choose that physician; Missouri lets the employer choose. Why that difference decides claims.
Why does the insurance company’s doctor blame degeneration?
An examiner hired by an insurer will often admit the injury. Then the examiner blames most of the impairment on degeneration that came before it. That is the apportionment argument. It is the standard way to shrink a claim without denying it outright.
The answer is not outrage. It is a record that shows what you could do before, what changed, and when. That is why the first visit after an injury matters so much more than the fifth.
Where the metabolic picture comes into it
There is a second reason a silent condition starts to hurt and then refuses to settle. It has nothing to do with the accident. Connective tissue in an inflamed, insulin-resistant body heals badly and stays sensitized longer.
That is not a defense argument. It is a treatment target. Ignoring it is why some injuries never resolve, no matter what is injected. Why pain will not heal — the metabolic terrain explains the mechanism, and terrain before orthobiologics covers the sequencing.
Orthobiologics inside a claim
Platelet-rich plasma and marrow-derived treatments come up often in injury cases. They are one of the few areas where the medical talk and the claims talk pull in different directions.
Medically, they fit a defined set of problems — partial tendon tears, some joint injuries, selected disc and facet uses. That is where we use them, and we tell you plainly whether your injury is one of them.
On the claims side the recurring dispute is coverage. These procedures are commonly excluded by health plans, and that exclusion is then characterized in correspondence as the treatment being unproven. Those are different claims: one is a contractual decision, the other is a statement about evidence, and the evidence base is considerably better than the denial letters imply. The distinction, set out properly.
Where they are used in an injury case, documentation decides whether the cost is recoverable. Society guidance exists and is worth citing in a file: ASIPP guidance on PRP and BMAC after back injury and orthobiologics in personal injury both cover what a defensible record looks like.
And as elsewhere on this site, the terrain sets the ceiling. An orthobiologic injected into a body that is not in a state to repair tissue is money spent against physiology: terrain before orthobiologics.
What are the odds my injury gets better?
We give a realistic estimate, not a hopeful one. Some cases respond well and predictably. Some are unclear and worth a diagnostic step before committing to anything. And some have a poor outlook whatever is done, usually because the tissue is gone rather than injured.
Patients tell us no one else said this to them early. Saying it also protects the claim. A plan built on an inflated promise collapses when it does not deliver. The file then reads as failed treatment, not as an outcome we predicted correctly.
What we will not put in a report
We will not record an impairment we did not find. We will not describe a mechanism we cannot support. That sounds obvious until you have seen a file collapse over one overstated line. That one line let a defense expert paint the whole record as advocacy.
The flip side is that when we do document something, it holds up. A careful record that holds up is worth more to you than a generous one that does not survive the first serious challenge.

Frequently asked questions
How far is the clinic from Glen Carbon?
About thirty-five minutes via I-270 west to 4477 Woodson Rd, Suite 202, next to Lambert Airport with on-site parking.
They say my back problem is degenerative, not the injury.
Both can be true at once. Illinois compensates the aggravation of a condition that was previously asymptomatic (causing no symptoms): how aggravation is proven.
I had a prior injury years ago. Does that disqualify me?
No. An employer takes the worker as found: the eggshell principle.
Who chooses the doctor in an Illinois work comp case?
You do, with two choices plus referrals. That is the opposite of the Missouri rule: Missouri and Illinois compared.
Why does my first appointment after a work injury matter so much?
Because it starts the record your claim runs on. Proving that work aggravated a condition takes a before and an after. What could you do before the injury, what changed, and when? That record has to be written down at the time, not rebuilt at a hearing. It is also largely the same record that produces good treatment. That is why the first visit matters so much more than the fifth.
Why does the insurance company’s doctor say my injury is just degeneration?
An examiner hired by an insurer will often admit the injury. Then the examiner blames most of the impairment on degeneration that was already there. That is the apportionment argument, the standard way to shrink a claim without denying it outright. The answer is not outrage. It is a record that shows what you could do before, what changed and when.
My health plan called PRP unproven. Is that true?
A coverage exclusion and a statement about evidence are different things. Health plans commonly exclude platelet-rich plasma and marrow-derived treatments, and that contractual decision is then described in letters as the treatment being unproven. The evidence base is considerably better than those denial letters imply. In an injury case, documentation decides whether the cost is recoverable, and we are candid about which injuries these treatments suit.
