Failure to Diagnose
By Jason Matzus | Founder, Matzus Law, LLC
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.
Our Pittsburgh-based firm is experienced in litigating all types of failure to diagnose cases, including:
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:
Get medical care immediately. Then, speak with a qualified medical malpractice attorney. At Matzus Law, we’ll review the facts of your case, consult experts, and determine if the harm was caused by a preventable diagnostic error. If it was, we’ll help you hold the responsible parties accountable.

“He’s Brilliant. Jason Matzus is a lawyer you thank God is on your side. He led my brother and I through one of the most painful times in our lives with great kindness. … at a time it was hard to trust. Jason, we trusted completely to represent our father. Jason’s intuition and command of voluminous details was immaculate. His direction impeccable. John Adams (founding father) stated, ‘Facts are stubborn things.’ Jason was able to take the facts and handle the absurd. He choreographed the case so it was piercingly true and definitive, and could no longer be manipulated. From the very beginning till the very end. Our father found Jason, and we could not have been prouder or more relieved to have been represented by him. Jason made sure that by the end of the case, people knew our father…not as an old man, but instead a vibrant, youthful, well-respected, uniquely-creative, and deeply, deeply loved man. Jason’s talent is beyond. He is outstanding. The Jaffe family is forever grateful for him.”
“I am so grateful for Matzus Law, LLC. Jason worked very hard for my children and me. When our world was turned upside down, Jason was caring and compassionate as he worked nonstop to help us through a very difficult time. Throughout my experience, Jason made sure I understood every detail and helped me make the best decisions for myself and my children. Once our fight began, Jason became a courtroom gladiator; fighting for me and my children. I will be forever grateful for all that Matzus Law has done for me. Jason and his legal team have given my children a legacy from their late dad, that they otherwise would not have.”
“I am so thankful that God directed us to Matzus Law after our car accident. We were told by one firm that our case was not worth what we owed in medical bills. We disagreed and so did Jason. He and his staff did an excellent job fighting for us! We highly recommend Matzus Law, LLC!”
“Jason Matzus is a wonderful attorney. I was very apprehensive of the process and Jason explained it very clearly and was there to guide me and answer questions…every step of the way. He was very professional and extremely knowledgeable, but also down to earth. He was extremely patient, as I was very nervous throughout the process. He was calming and informed me of the next steps in the process. I am so glad that Jason was my attorney. I am pleased with the results of the case. I really believe he is the best.”
