Workers’ compensation covers most on-the-job injuries in Pennsylvania, but it doesn’t cover everything. If someone outside your employer caused or contributed to your injury, such as a negligent driver, a defective machine, or an unsafe property, you may have a third-party claim on top of your workers’ comp case. Filing both can put significantly more money in your pocket than workers’ comp alone, but the rules are different and the deadlines are not the same.

Workers’ compensation is a no-fault system. You generally cannot sue your employer or a coworker, even if their negligence played a role in your injury. A third-party claim is a personal injury lawsuit against anyone outside your employer who caused or contributed to your injury.
Common examples include:
- Defective machinery: if equipment spontaneously malfunctions, you may have a product liability claim against the manufacturer
- Car accident while driving for work: you may be able to sue the at-fault driver
- Injury on someone else’s property: a property owner who fails to warn you of a known hazard may be liable
- Toxic chemical or substance exposure: if a manufacturer’s product caused your illness, you may have a claim against them
- Slip and fall caused by a third-party janitorial company that left no wet floor warning
According to the Pennsylvania Department of Labor and Industry’s Bureau of Workers’ Compensation, 14,041 workplace injuries and illnesses were reported in Philadelphia County in 2024. A portion of those cases involve third-party liability that goes beyond what workers’ comp covers.
How Do You Know If You Can File a Third-Party Claim?
To file a third-party claim for a workplace injury, you need to establish four things:
- Duty of care. The third party had a responsibility to act reasonably and avoid causing you harm. Property owners, equipment manufacturers, and drivers all owe this duty.
- Breach. The third party failed to meet that duty through their action or inaction.
- Causation. That breach directly caused your injury.
- Damages. Your injury resulted in financial losses, such as medical bills, lost wages, or reduced earning capacity.
Your Philadelphia workers’ compensation lawyer will review your case to determine whether these elements are present before moving forward.
Can You File for Workers’ Compensation and a Third-Party Claim for the Same Injury?
Yes, in most cases. You can pursue workers’ compensation and a third-party lawsuit at the same time for the same injury. What you cannot do is collect double benefits.
If you receive workers’ comp benefits and later win a third-party lawsuit, Pennsylvania law gives your employer’s insurance carrier the right to be repaid for what they paid out. This is called subrogation. It is not a reason to avoid filing. A successful third-party case typically yields far more in total compensation than workers’ comp alone. You can also negotiate the amount they might try to take down if you can prove they would leave you inadequately compensated. Subrogation does affect how your attorney structures your recovery strategy, and it is worth discussing with your lawyer before deciding which path to pursue.
The deadlines are also different. You have three years to file a workers’ compensation claim in Pennsylvania, but only two years from the date of injury to file a third-party personal injury claim under 42 Pa. C.S.A. § 5524(2). Do not assume both follow the same timeline.
What’s the Difference Between Compensation in Workers’ Compensation and Third-Party Claims?
Workers’ compensation covers medical bills and two-thirds of your average weekly wage, up to $1,394 per week as of 2026. A third-party claim can pursue pain and suffering, loss of earning capacity, and other damages that workers’ comp does not cover.
The value depends on the specifics of your case, including the extent of your injury and the strength of the evidence against the third party.
What a Philadelphia Workers’ Comp Lawyer Can Do For You
Employers and their insurance carriers routinely challenge workers’ compensation claims. They may dispute the extent of your injury, push you toward a company-approved doctor, or delay the process to pressure you into settling for less. When a third party is also involved, their legal team will work to minimize their share of liability.

Frequently Asked Questions About Third-Party Claims and Workers’ Compensation Cases in Philadelphia
What is the Difference Between Workers’ Compensation and a Third-Party Claim in Philadelphia, PA?
The difference between workers’ compensation and a third-party claim in Philadelphia, PA, is that workers’ compensation is a no-fault system that covers medical bills and a portion of lost wages after a work injury, while a third-party claim is a personal injury lawsuit filed against someone outside your employer who caused or contributed to your injury. When both apply, you can pursue them at the same time, though you cannot collect double benefits for the same losses.
Can I Sue Someone Other Than My Employer for a Workplace Injury?
Yes, you can sue someone other than your employer for a workplace injury if a person or company outside of your workplace caused or contributed to your injury. Common examples include negligent drivers, equipment manufacturers, outside contractors, and property owners. A lawyer can help determine whether a third party may be legally responsible.
What Damages Can I Recover in a Third-Party Workplace Injury Claim?
You may be able to recover a broader range of damages in a third-party workplace injury claim than through workers’ compensation alone. This can include full lost wages, loss of earning capacity, pain and suffering, and other losses related to your injury. The value of your case depends on the specific facts and the severity of your injuries.
How Long do I Have to File a Third-Party Workplace Injury Claim in Philadelphia?
You generally have two years from the date of your injury to file a third-party personal injury claim in Philadelphia under 42 Pa. C.S.A. § 5524(2). Workers’ compensation has a separate deadline, usually three years from the date of injury. Do not assume both claims follow the same timeline.
Why Should I Hire a Third-Party Claims and Workers’ Compensation Lawyer in Philadelphia?
You should hire a third-party claims and workers’ compensation lawyer in Philadelphia because work injury cases become complicated quickly when insurance companies and multiple parties are involved. A lawyer at Munley Law can identify all potential sources of compensation, gather the evidence needed to establish liability, and make sure no deadline slips.
