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 particular claim belongs with your attorney.
The pre-existing condition argument
Degenerative disc disease, arthritic change, an old sports injury — almost everyone over thirty has something on imaging. When a claim is disputed, those findings are produced as the real explanation and the injury is 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.
What proving aggravation actually requires
It requires a before and an after, established clinically rather than asserted. Function before the injury, function after, and a mechanism that plausibly connects the two — documented at the time rather than reconstructed at a hearing.
Proving exacerbation sets out what that record looks like, and it is largely the same record that produces good treatment.
And why you should choose who writes it
And 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.
Reading the other side’s report
An examiner retained by an insurer will often concede the injury and then attribute most of the impairment to degeneration that predates it. That is the apportionment argument, and it is the standard route to reducing a claim without denying it outright.
The counter is not indignation. It is a record that establishes what you could do before, what changed, and when — which is why the first appointment after an injury matters so much more than the fifth.
Where the metabolic picture comes into it
There is a second reason a previously silent condition becomes symptomatic and then refuses to settle, and it has nothing to do with the accident: connective tissue in an inflamed, insulin-resistant body heals badly and stays sensitised longer.
That is not a defense argument, it is a treatment target, and ignoring it is why some injuries never resolve regardless of 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 frequently in injury cases, and they are one of the few areas where the clinical and the claims conversation actively diverge.
Clinically they are appropriate for a defined set of problems — partial tendon tears, some joint injuries, selected disc and facet applications — and inappropriate for others, and we are candid about which is which rather than offering them as a general answer to injury.
On the claims side the recurring dispute is coverage. These procedures are commonly excluded by health plans, and that exclusion is then characterised 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 we tell people the odds are
We give a realistic estimate rather than an encouraging one. Some presentations respond well and predictably; some are ambiguous 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.
Saying so early is the part patients tell us they were not offered elsewhere. It also protects the claim: a plan built on an inflated expectation collapses when it does not deliver, and the file then reads as failed treatment rather than as an accurately predicted outcome.
What we will not put in a report
We will not record an impairment we did not find, and we will not describe a mechanism we cannot support. That sounds obvious until you have seen a file collapse because one overstated line let a defense expert characterise the entire record as advocacy.
The corollary is that when we do document something, it is defensible. A conservative 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, and Illinois compensates the aggravation of a condition that was previously asymptomatic: 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.
