Introduction: When Your Employer Blames Your Injury On An Old Problem

Picture this: a Pueblo warehouse worker with a 10-year-old back strain suffers a new lifting injury in 2025. The insurance carrier responds by saying it’s just your old back problem. This scenario plays out across Colorado every day.

Here’s what insurers don’t want you to know: Colorado workers' compensation can cover work related injuries that aggravate a pre existing condition, including coverage for medical bills and the right to receive benefits if the work incident worsens your prior condition—even if your original injury came from a car crash, sports accident, or prior job.

Johnston Law Firm, LLC in Pueblo regularly handles workers comp claims where insurers argue pre existing injury to reduce or deny benefits. Steve Johnston also handles personal injury and social security law, which matters if your work injury leads to long-term disability.

What Counts As A Pre-Existing Condition In Colorado Workers’ Comp?

A preexisting condition is any medically documented injury, illness, or chronic medical condition you had before your current workplace injury. Any employee covered by Colorado workers' compensation insurance must disclose pre-existing conditions when filing a claim. The key question is whether documentation exists in your medical history.

Common examples include:

• Prior herniated or bulging discs

• Chronic low back pain

• Knee surgeries from skiing or football

• Old shoulder tears from construction work

• Carpal tunnel from repetitive motions

• Asthma, COPD, or arthritis

• Diabetes-related complications

Insurers commonly pull 5+ years prior of medical records searching for anything they can label pre existing. However, undiagnosed aches with no medical care documented are harder for them to use against you.

The key factor isn’t whether you had a prior condition—it’s whether your job aggravated that existing condition enough to require new treatment.

Claimants are legally required to disclose prior injuries on claim forms, and failure to do so can result in claim denial or fraud charges.

Aggravation vs. Natural Progression: The Core Battle In These Cases

Colorado workers compensation law differentiates between:

Practical examples:

• A Pueblo nurse with mild, controlled arthritis whose knee suddenly swells after months of long hours on 12-hour shifts

• A Fremont County truck driver whose old neck injury flares dramatically after a 2026 loading accident

Insurers routinely argue your current pain represents natural progression due to age. But colorado law focuses on whether the work injury was a significant contributing factor to the worsening—not the only cause.

If your symptoms, abilities, or medical needs changed significantly after a dateable workplace incident, you may have a strong aggravation claim worth discussing with an experienced workers comp attorney.

How Pre-Existing Conditions Affect Your Right To Benefits

Having existing conditions in Colorado does NOT automatically disqualify you from workers comp benefits. This is a critical aspect many injured workers misunderstand.

The employer and workers compensation insurance are responsible for the portion of disability caused or worsened by the work injury, even if you were more vulnerable due to prior injuries.

Workers comp benefits you may still receive:

• Medical treatment for the work-caused worsening

• Temporary disability and wage benefits while off work

• Permanent impairment benefits when appropriate

• Coverage for diagnostic tests and medical care

If a work injury activates a dormant condition that impairs your ability to work, you may be eligible for full benefits for the new state of that condition.

In some cases, medical experts may apply apportionment—dividing responsibility between the old condition and new injury. Without legal representation, workers in Pueblo, La Junta, and Cañon City often accept low settlements because they don’t understand how this should work.

Proving Work Aggravated Your Pre-Existing Condition

These cases are won or lost on medical evidence and how clearly you demonstrate a before-and-after change.

Gather and preserve:

• Prior medical records and imaging (MRIs, X-rays)

• Work incident reports

• Coworker witness statements

• Personal timeline of symptoms before and after

Be honest with company doctors about your medical history, but clearly describe how this new injury is different or makes your condition worse than before.

Insurers often send workers to independent medical examination appointments where doctors may downplay work aggravation. Your own treating physicians and additional medical experts can counter these opinions.

Johnston Law Firm can coordinate with your physicians, help frame the medical issues, and prepare you for IMEs. Call (719) 309-9484 or reach out online to review your evidence.

Common Tactics Insurers Use With Pre-Existing Conditions

Watch for these insurance company strategies:

• Claiming your symptoms never changed after the accident

• Blaming everything on age or long-standing arthritis

• Cherry-picking old chart notes from years prior

• Mischaracterizing your job duties

• Using pre-existing conditions as a reason to deny coverage, arguing the injury was not work-related or that symptoms existed before the incident

Adjusters sometimes pressure workers in Pueblo and surrounding counties to give recorded statements that minimize the accident. Some insurers delay authorizing MRIs or specialist referrals by arguing your condition is old, hoping you’ll give up. Workers' compensation claims involving pre-existing conditions frequently face delays and denials due to these tactics, which can frustrate claimants and sometimes cause them to abandon their claims.

They may send you to defense-friendly doctors who write reports emphasizing degenerative findings rather than the acute work injury.

Don’t take a denial at face value. An experienced workers compensation attorney knows how to challenge these tactics and gather evidence to support your claim.

Steps To Take After A Work Injury When You Have A Pre-Existing Condition

Follow this checklist:

1. Report the injury in writing to your employer within Colorado’s deadline

2. Seek immediate medical care and describe the exact workplace event

3. Document everything: date, time, what you were lifting, slip/trip details

4. Clearly state how symptoms changed compared to your usual baseline

5. Keep detailed notes: daily pain levels, limitations, medications, missed activities

Avoid toughing it out or delaying reports. Gaps in medical documentation can be used against you as proof nothing truly changed.

Contact Johnston Law Firm early so we can help you avoid common mistakes and meet deadlines with the Colorado Division of Workers’ Compensation.

What If Your Workers’ Comp Claim Is Denied Because Of A Pre-Existing Condition?

Denials based on alleged pre existing conditions are common in Colorado—but the law gives you the right to fight back.

The dispute process includes:

• Objecting to the denial

• Requesting a hearing before a workers compensation judge

• Presenting medical testimony and evidence

• Pursuing appeals if necessary

These proceedings involve strict deadlines and technical medical issues. Self-representation can be risky for complex aggravation claims.

If your workers compensation claim was denied or benefits cut off, call (719) 309-9484 or send a confidential message to discuss appeal options.

FAQ: Pre-Existing Conditions And Colorado Workers’ Compensation

Does it matter if my old injury was from a car accident instead of a prior job?

No. Colorado workers comp does not require the original condition to be work-related. What matters is whether your current job duties significantly aggravated that condition. A 2018 car crash neck injury that becomes much worse after a 2026 warehouse incident can still be covered under workers compensation as an aggravation.

Can I still get workers’ comp if I was working with restrictions before this new injury?

Yes. Having prior permanent restrictions or a light-duty job does not automatically disqualify you. The issue is whether the new injury caused further loss of function or required new treatment. Keep copies of old work notes and restrictions to show the change after your new workplace injury.

Will I have to reveal all my old medical records to the insurance company?

Insurers commonly request 5+ years of records, but disputes arise over scope. An attorney can help limit overly broad requests under colorado law. Strategic handling of medical release forms protects privacy while proving work-related aggravation.

What if I was asymptomatic for years before the work injury?

Being pain-free or not needing treatment before the work event often strengthens your argument. This quiet period shows that work—not natural progression—caused the current disability. Gather proof of years without seek medical care to support your workers compensation case.

Can I pursue a personal injury case and a workers’ comp claim at the same time?

In situations like a delivery driver hit by another vehicle while working, you may have both claims. These involve complex coordination including liens and offsets. Because Johnston Law Firm handles both workers’ compensation and personal injury, we can design a strategy protecting your overall recovery and helping you receive fair compensation.
