Allentown, Pennsylvania Fault Rules for Medical Malpractice: What Patients Must Know

TL;DR: Pennsylvania uses a modified comparative negligence system that directly controls how fault is divided—and how much money you can recover—in a medical malpractice case filed in Allentown. If a jury finds you 50% or less at fault, you can still recover, but your award is reduced by your share of blame. Hit 51% or more and you recover nothing. Deadlines, a certificate of merit requirement, and the Fair Share Act add further complexity. Talk to us today to get matched with a vetted Pennsylvania medical malpractice attorney.

Medical malpractice in Pennsylvania is broadly defined as negligent or unskilled treatment by a healthcare professional that deviates from accepted medical care standards and results in injury to the patient. To win a claim, you must prove four elements:

1. Duty of care: A doctor-patient relationship existed, creating a legal obligation to meet the accepted standard of care.
2. Breach: The provider failed to meet that standard—through a misdiagnosis, surgical error, medication mistake, or inadequate follow-up.
3. Causation: The breach directly caused your harm. Expert testimony is almost always required to establish this link.
4. Damages: You suffered measurable harm—medical bills, lost wages, pain and suffering, or other losses.

Claims can be brought not only against physicians but also against nurses, dentists, pharmacists, and other licensed healthcare providers. Missing any of the four elements, or failing to counter a comparative fault defense, can significantly weaken your case.

The single most important fault rule for Allentown patients is Pennsylvania's modified comparative negligence standard, codified at 42 Pa.C.S. § 7102. Under this rule, your own negligence does not automatically bar your recovery—as long as your share of fault is not greater than the defendant's.

Here is how it works in practice:

• Your fault is 20%, the doctor's fault is 80%: You recover 80% of your total damages.
• Your fault is 50%, the doctor's fault is 50%: You still recover—but only half of your damages.
• Your fault is 51% or more: You recover nothing. Pennsylvania's "51% bar" ends your claim entirely.

Importantly, the burden of establishing comparative negligence rests on the defendant, not on you. Insurers and defense attorneys will work hard to push your share of blame past the 50% threshold, because every percentage point they assign to you reduces—or eliminates—what they owe.

Medical errors often involve more than one party—a surgeon, an anesthesiologist, a hospital system, a nursing team. When multiple defendants share the blame, Pennsylvania's Fair Share Act (also codified at 42 Pa.C.S. § 7102) determines how much each one owes.

The key threshold is 60%:

• A defendant found less than 60% liable generally pays only their proportionate share of the verdict.
• A defendant found 60% or more liable is jointly and severally liable—meaning they can be required to pay the full judgment, including the share of any co-defendant who cannot pay.

This matters enormously in Allentown hospital cases. If a hospital system and an attending physician both contribute to your injury, how fault is allocated between them can determine whether you actually collect your award. A skilled attorney will structure your case to maximize the chance that at least one defendant crosses the 60% threshold—or to preserve joint and several liability through other legal theories.

Under 42 Pa.C.S. § 5524(2), you generally have two years from the date you discovered—or reasonably should have discovered—that a healthcare provider's negligence caused your injury to file a medical malpractice lawsuit in Pennsylvania.

Several important deadline rules apply:

• Discovery rule: The two-year clock starts when you knew, or reasonably should have known, about the malpractice—not necessarily the date of treatment.
• Minors: For patients under 18, the two-year period does not begin until they turn 18, giving them until age 20 to file under 42 Pa.C.S. § 5533.
• Wrongful death: If the patient died, the two-year window runs from the date of death under MCARE Act § 1303.513(d).
• Government facilities: If a public hospital is involved, you may also need to file a written notice of claim within six months of the injury under 42 Pa.C.S. § 5522.

Do not wait. Missing these deadlines typically means permanent loss of your right to compensation. Get matched in under a minute with a Pennsylvania attorney who can protect your timeline.

Pennsylvania is one of the states that requires a Certificate of Merit (COM) before a medical malpractice case can proceed. Under Pennsylvania Rule of Civil Procedure 1042.3, the certificate must be filed with your complaint or within 60 days after filing.

The certificate must be signed by a qualified medical expert who has reviewed your case and states there is a reasonable probability that the provider's conduct fell below accepted professional standards and caused harm. If the certificate is not filed on time—and no court extension was properly obtained—the defendant may seek a judgment dismissing your case entirely.

Missing this step is one of the most common reasons valid malpractice claims are thrown out in Pennsylvania. An experienced attorney will identify and retain the right expert early, before the clock runs out.

Pennsylvania does not cap compensatory damages in medical malpractice cases against private healthcare providers. That means you can pursue the full value of your losses, which may include:

• Past and future medical expenses for corrective treatment and rehabilitation
• Lost wages and reduced future earning capacity
• Physical pain and suffering, emotional distress, and loss of enjoyment of life
• Loss of consortium (the impact on your relationship with a spouse)

Punitive damages are available in limited circumstances. Under MCARE Act § 1303.505(d), punitive damages against an individual physician cannot exceed 200% of the compensatory damages awarded.

It means fault is divided as a percentage between you and the defendant. Your compensation is reduced proportionally by your share of blame. As long as you are 50% or less at fault, you can still recover. If you are found 51% or more at fault, Pennsylvania law bars any recovery entirely.

Possibly. Pennsylvania law allows for shared fault—so ignoring advice may reduce your award, but it does not automatically eliminate your claim. Defendants must prove your conduct was negligent and that it caused or contributed to the harm. An attorney can evaluate how strong their comparative fault argument actually is against you.

Yes. Under Pennsylvania Rule of Civil Procedure 1042.3, almost every malpractice lawsuit requires a certificate from a qualified medical expert filed with your complaint or within 60 days after. Without it, the defendant can seek dismissal. This is why you need an attorney involved early—expert review takes time, and courts enforce this deadline strictly.

You can name multiple defendants. Under the Fair Share Act, each defendant pays their proportionate share of fault, unless one is found 60% or more liable—in which case joint and several liability may apply, meaning that defendant can be required to pay the entire judgment. Identifying all responsible parties is a key part of building your case.

Generally two years from when you discovered—or reasonably should have discovered—the malpractice, under 42 Pa.C.S. § 5524(2). Minors have until age 20. If a public hospital is involved, a six-month notice-of-claim deadline may also apply. Because exceptions are fact-specific, consult an attorney as soon as possible to lock down your deadline.

Pennsylvania's fault rules are layered—comparative negligence, the Fair Share Act, a strict certificate of merit requirement, and tight filing deadlines can all affect whether you recover, and how much. The defense team on the other side of your case knows these rules cold and will use every one of them to limit your payout.
