Contested Workers’ Comp Claim in Connecticut — What a Form 43 Means and What to Do Next
If you’ve received a Form 43, it means the insurance company is denying your workers’ compensation claim. For many people, this is the moment they realize something is wrong and they’re not sure what to do next.
Located in East Granby, CT, Mark Merrow works with injured workers across Hartford County and surrounding areas to help them understand what a Form 43 means and what to do next.
A Form 43 does not mean your case is over. It means the insurance company is choosing to contest it.
Why Insurance Companies File a Form 43
In Connecticut, the insurance company has a limited time to accept or deny a workers’ compensation claim. In many cases, a Form 43 is filed not because the claim has been fully investigated, but because the insurer has not made a decision within that timeframe.
On the form, you’ll often see phrases like:
- “Claim is personal in nature”
- “Did not arise out of employment”
- “Pre-existing condition”
These are standard defenses used by insurance companies. They do not necessarily mean your claim isn’t valid.
One of the most common issues involves pre-existing conditions. Many injured workers assume they don’t have a case if they’ve had prior problems with the same body part—but that’s not how Connecticut law works.
If a work injury aggravates a prior condition—meaning it makes it worse or accelerates the need for treatment—you may still be entitled to benefits.
What Happens Next
After a Form 43 is filed, your claim becomes disputed. It may move toward a formal hearing before a workers’ compensation Administrative Law Judge.
At this stage, most people are trying to understand what this means and what happens after a Form 43 denial. The next steps depend on your situation, but timing matters.
