When you walk into a hospital or a doctor’s office, you place your trust—your life, in many cases—in the hands of medical professionals. You expect skill, diligence, and above all, answers. But when a serious medical condition goes undiagnosed, the consequences can be devastating. At Matzus Law, LLC, we represent patients and families across Pennsylvania who have suffered due to a medical provider’s failure to diagnose or delayed diagnosis.
Whether it’s a missed cancer diagnosis, a stroke mistaken for a migraine, or abnormal test results that no one followed up on, failure to diagnose is among the most common—and most harmful—forms of medical negligence. I’ve spent my career holding healthcare providers accountable when those failures cause unnecessary suffering, long-term harm, or wrongful death.
Failure to diagnose cases often involve conditions where time is everything:
When medical providers ignore red flags, misread test results, or dismiss symptoms that any reasonably careful doctor should have investigated further, the law allows you to pursue justice. Our role is to help you do exactly that—with the skill, compassion, and tenacity your case deserves.
Every physician, whether working in a chaotic ER or a quiet primary care practice, has a duty to provide care that meets a reasonable standard. But time and again, we see common breakdowns that lead to tragedy:
If another doctor in the same situation would have made the diagnosis, but your doctor didn’t—and harm resulted—that is grounds for a medical malpractice claim in Pennsylvania.
We start with a detailed root cause analysis. We work with top-tier medical experts who understand how these cases unfold and what should have happened. Then, we connect the dots between that missed diagnosis and the harm that followed.
We’re here to answer your questions, explain your options, and help you move forward—whatever that looks like for you.

Unfortunately, many of our clients did everything right—and the system still failed them. But there are steps patients can take to reduce the risk of diagnostic errors:
That said, if you’re reading this, it may already be too late to prevent the harm. But it’s not too late to demand accountability.
Misdiagnosis occurs when a patient is told they have the wrong condition—or told there’s nothing wrong at all—when a serious illness is present. Research shows nearly 12 million Americans are misdiagnosed each year in outpatient settings. About 6 million of those patients suffer serious harm.
Conditions frequently misdiagnosed include:
Cancer
Heart attack
Stroke
Meningitis
Sepsis
Necrotizing fasciitis
Pulmonary embolism
Spinal epidural abscess
Subarachnoid hemorrhage
