Pennsylvania Medical Malpractice — Requirements & Limits

Medical malpractice claims in Pennsylvania carry a higher burden of proof, stricter procedural requirements, and tighter deadlines than ordinary personal injury cases. The plaintiff must prove that a healthcare provider deviated from the accepted standard of care and that this deviation — not the underlying illness or condition — caused the harm.

Not every bad outcome is malpractice. To have a valid claim, four elements must be established:

In virtually all medical malpractice cases, expert testimony is required to establish both the standard of care and the breach. The expert must be a qualified medical professional — typically a practitioner in the same specialty as the defendant. Without a qualified expert willing to testify, the case cannot proceed.

Pennsylvania imposes specific procedural requirements on medical malpractice claims that must be satisfied before or at the time of filing:

• Certificate Of Merit: Certificate of merit must be filed with or shortly after the complaint, attesting that an appropriate licensed professional has supplied a written statement that the defendant deviated from acceptable professional standards. §Pa.R.C.P. 1042.3

Medical malpractice in Pennsylvania has specific deadline rules that differ from the general personal injury Statute of limitations §40-1303.513.

2 years from discovery; 7-year repose under MCARE Act ([40 P.S. § 1303.513]). Certificate of merit required. Pennsylvania is a choice no-fault auto state.

The general personal injury statute of limitations is 2 years §42-5524.

Discovery rule

Pennsylvania recognizes a discovery rule — the clock may start when the injury was discovered or should have been discovered, rather than when the act or omission occurred §42-5524. Discovery rule applied by case law: SOL runs from date the plaintiff knew or should have known of the injury and its cause.

Statute of repose §40-1303.513

Pennsylvania imposes a 7-year statute of repose — an absolute outer limit that cannot be extended by the discovery rule or tolling. Seven-year statute of repose for medical malpractice from date of act or omission ([40 P.S. § 1303.513]). MCARE Act.

Pennsylvania imposes caps on certain categories of medical malpractice damages:

• No statutory noneconomic damages cap (prior $250K cap struck down) (Pennsylvania's MCARE Act originally included a $250K noneconomic cap, but the Pennsylvania Supreme Court struck it down as unconstitutional in Zauflik v. Pennsbury School District (2014). No current noneconomic cap.) §40-1303.505

• Surgical errors — wrong site, retained instruments, nerve damage, anesthesia errors
• Misdiagnosis or delayed diagnosis — failure to diagnose cancer, heart attack, stroke, or infection in time to prevent progression
• Medication errors — wrong drug, wrong dose, dangerous drug interactions, failure to check patient history
• Birth injuries — failure to monitor fetal distress, improper use of forceps or vacuum, delayed C-section
• Failure to treat — correct diagnosis but inadequate treatment, premature discharge, failure to refer to a specialist
• Failure to obtain informed consent — performing a procedure without adequately explaining risks and alternatives

Pennsylvania follows modified comparative fault — damages are reduced by the injured person's percentage of fault, but if the injured person is 51% or more at fault, they recover nothing.

This rule applies in medical malpractice just as in other personal injury cases. The defense may argue the patient contributed to the harm — by failing to follow post-operative instructions, not disclosing relevant medical history, or delaying follow-up care.

• Request your complete medical records — you have a legal right to them. Do this before anything else.
• Do not delay — the combination of filing deadlines, pre-suit requirements, and the time needed for expert review means that early action is essential.
• Continue treating with other providers — mitigating your injuries is both medically necessary and legally important.
• Document the timeline — note when symptoms appeared, what you were told by providers, and when you first suspected something went wrong.
