Medical Malpractice Laws in Pennsylvania (2026): Deadlines & Caps

Pennsylvania is one of the states where the constitution itself shapes the damages rules, and where a procedural step early in the case can end it. A patient generally has two years to sue under 42 Pa.C.S. 5524, there is no cap on damages recoverable from private health care providers, and a certificate of merit signed by an attorney must be filed with or shortly after the complaint under Pa.R.C.P. 1042.3.

This page is general legal information, not legal advice, and it is part of our Medical Malpractice Laws by State series. The deadline and the certificate-of-merit step depend on the facts, so confirm your situation with a licensed Pennsylvania attorney.

What counts as medical malpractice in Pennsylvania?

Medical malpractice in Pennsylvania is professional negligence by a health care provider that causes injury to a patient. The plaintiff must establish the applicable standard of care, that the provider deviated from it, and that the deviation caused the harm. Physicians, hospitals, nurses, and other licensed providers can be liable, and a hospital can be responsible for its own negligence and, in many cases, for that of its staff. A bad result alone does not prove malpractice; the care must have fallen below accepted professional standards.

The statute of limitations to sue in Pennsylvania

Under 42 Pa.C.S. 5524, a personal-injury action, including a medical malpractice claim, must be commenced within two years. Pennsylvania applies the discovery rule, so the two-year clock generally begins when the plaintiff knew, or through reasonable diligence should have known, of the injury and that it was caused by another's conduct. This matters in malpractice cases where the harm or its connection to the treatment is not immediately apparent.

Pennsylvania's statute of repose: struck down

Pennsylvania once had a seven-year statute of repose for medical malpractice in the MCARE Act, 40 P.S. 1303.513, which barred most claims filed more than seven years after the negligent care regardless of discovery. That repose period is no longer enforceable. In Yanakos v. UPMC, 218 A.3d 1214 (Pa. 2019), the Pennsylvania Supreme Court held the seven-year repose unconstitutional under Article I, Section 11 (the open-courts provision) of the Pennsylvania Constitution, because the limit was not substantially related to its stated goals. The practical effect is that the two-year discovery rule, not a fixed seven-year outer cutoff, governs timeliness, subject to other doctrines.

Damage caps in Pennsylvania: there are none for private providers

This is one of the clearest points in the country: Pennsylvania does not cap compensatory damages in medical malpractice cases against private health care providers, and the bar is constitutional, not just statutory. Article III, Section 18 of the Pennsylvania Constitution provides that, outside narrow areas the constitution itself authorizes such as workers' compensation, the General Assembly may not limit the amount recoverable for injuries resulting in death or for injuries to persons or property.

Because of that provision, the legislature cannot enact a noneconomic or total damages cap on claims against private doctors, hospitals, and other providers. There is therefore no statutory ceiling on economic damages such as medical bills and lost income, and no ceiling on noneconomic damages such as pain and suffering, in malpractice cases against private defendants. Caps can apply to certain governmental defendants under separate sovereign-immunity and political-subdivision statutes, which is a different framework from a private malpractice suit.

Watch out: Some general summaries lump Pennsylvania in with cap states. For private providers, Pennsylvania has no compensatory damages cap, and Article III, Section 18 of the state constitution prevents one. Different rules apply to suits against government entities.

Certificate of merit under Pa.R.C.P. 1042.3

Pennsylvania requires a certificate of merit in professional-liability cases, including medical malpractice, and missing it can be fatal to the claim. Under Pa.R.C.P. 1042.3, the plaintiff (or the plaintiff's attorney) must file a certificate stating one of three things: that an appropriate licensed professional has supplied a written statement that there is a reasonable probability the care fell outside acceptable professional standards and caused harm; that the claim rests on another professional's conduct for which the defendant is responsible; or that expert testimony is unnecessary for the claim.

The certificate must be filed with the complaint or within 60 days after the complaint is filed, and a court may extend that period by up to 60 additional days for good cause. If the certificate is not filed on time and no extension applies, the defendant may seek a judgment of non pros, which dismisses the case for failure to prosecute. This is a true filing prerequisite, not an optional step.

The MCARE Act and expert qualifications

The Medical Care Availability and Reduction of Error (MCARE) Act governs much of Pennsylvania's malpractice landscape, including expert-witness qualifications. In general, an expert offering standard-of-care testimony must hold an unrestricted physician's license, be engaged in or recently retired from active clinical practice or teaching, be familiar with the applicable standard of care, and, where the defendant is board-certified, be board-certified in the same or a related specialty. These qualification rules also inform who can provide the written statement underlying the certificate of merit.

Comparative negligence in Pennsylvania

Pennsylvania follows modified comparative negligence. A plaintiff's recovery is reduced by the plaintiff's share of fault, and a plaintiff whose fault is greater than 50 percent is barred from recovering. In a malpractice case, that means a patient who is found mostly responsible for the harm may recover nothing, while a smaller share of fault simply reduces the award.

Wrongful-death medical malpractice in Pennsylvania

When malpractice causes death, Pennsylvania recognizes both a wrongful-death action under 42 Pa.C.S. 8301, brought for the benefit of statutory survivors, and a survival action under 42 Pa.C.S. 8302, brought by the estate for the decedent's own losses. These claims have their own beneficiaries and damages categories, and the certificate-of-merit requirement still applies. Because the deadlines and recoverable damages differ from a standard injury claim, identifying the correct action early matters.

How to evaluate and preserve a possible claim

While every situation is different and this is general information rather than legal advice, people who suspect malpractice in Pennsylvania often begin by gathering complete medical records and noting key dates, because the two-year clock under 42 Pa.C.S. 5524 can run quickly once the injury and its cause are known. Because Pa.R.C.P. 1042.3 requires a certificate of merit grounded in a qualified professional's review, an attorney typically arranges expert review early. Malpractice cases are commonly handled on a contingency-fee basis, and consulting a licensed Pennsylvania attorney promptly helps meet the certificate deadline and confirm the limitations period, though no attorney can promise a particular outcome or dollar amount.
