New York City Delayed Diagnosis Lawyer

A doctor’s job does not end at ordering tests. It includes reviewing results promptly, following up on concerning findings, communicating clearly with patients, and referring to specialists when a condition falls outside their expertise. When any of those responsibilities breaks down and a serious illness goes undetected for weeks, months, or even years, the damage can be irreversible. New York City delayed diagnosis lawyers handle exactly these situations, where a condition that was present and detectable was missed, dismissed, or never properly worked up, and where that failure changed what was possible for the patient.

Cancer diagnosed at Stage I looks very different from the same cancer diagnosed at Stage III. A heart attack identified in an emergency department within the first two hours looks different from one that sends a patient home with “indigestion.” The medicine does not change; the outcome does. That gap between what treatment was possible and what treatment became necessary because of a provider’s delay is the core of a delayed diagnosis claim in New York.

These cases sit at the intersection of medicine and law, and they require counsel who understands both. The medical questions are genuinely complex. Establishing what a physician should have done requires expert testimony, careful review of the full medical record, and a working knowledge of clinical standards. Mark David Shirian P.C. brings that level of preparation to every client who comes to us after being failed by a provider who should have caught something sooner.

What Delayed Diagnosis Actually Means in a Medical Malpractice Context

Delayed diagnosis is not the same as misdiagnosis, though the two are related. A misdiagnosis means the wrong condition was identified. A delayed diagnosis means the right condition was eventually found, but not in time. Both can support a malpractice claim, but the legal analysis differs because the question is not just what the doctor got wrong, it is what the doctor failed to do at the point when the diagnosis should have been made.

New York medical malpractice law evaluates a physician’s conduct against the standard of care, which is what a reasonably competent physician in the same specialty and in similar circumstances would have done. A delayed diagnosis claim asks: given this patient’s symptoms, history, and test results at the time of the visit, would a competent provider have ordered additional testing, made a referral, or reached the correct diagnosis? If the answer is yes, and a competent provider would have caught it, then the failure to do so may constitute malpractice.

The second element requires showing that the delay caused harm beyond what would have occurred with a timely diagnosis. This is called causation, and it is often the hardest part of a delayed diagnosis case to prove. You need medical experts who can speak to how the condition progressed during the delay, what treatment would have been available earlier, and how the patient’s prognosis changed because of the wait. In conditions like cancer, where staging governs treatment options and survival statistics directly, this analysis can be compelling. In other conditions, the causation argument requires more nuance. A New York City delayed diagnosis attorney who has handled these cases knows how to build that evidentiary foundation.

The Conditions Most Commonly at Issue in Delayed Diagnosis Claims

• Cancer: Breast, colon, lung, cervical, prostate, and melanoma are among the most frequently delayed diagnoses in litigation. Common failures include inadequate follow-up after an abnormal screening result, failure to biopsy a suspicious mass, or failure to refer to oncology after concerning lab findings.
• Heart Attack and Cardiac Conditions: Emergency departments across New York City see misattributed cardiac events regularly. Chest pain dismissed as anxiety or reflux, or atypical presentations in women that do not fit the “classic” pattern, can lead to a patient being sent home during an active cardiac event.
• Stroke: Stroke requires intervention within a narrow time window. A patient presenting with sudden neurological symptoms who is not assessed for stroke and treated promptly may lose permanent function that could have been preserved with earlier thrombolytic therapy or mechanical intervention.
• Infection and Sepsis: Serious bacterial infections can escalate to sepsis within hours. A provider who dismisses fever, elevated white blood cell counts, or signs of localized infection without appropriate culturing or antibiotic treatment may be liable when the infection becomes life-threatening.
• Pulmonary Embolism: Patients with risk factors for blood clots who present with shortness of breath and chest discomfort are sometimes sent home without imaging. A pulmonary embolism missed in this setting can be fatal within hours of an office visit or ER discharge.
• Appendicitis: Atypical presentations and overburdened emergency departments in New York City have both contributed to delayed appendicitis diagnoses, with perforation and serious complications resulting from what could have been a straightforward surgical intervention.
• Aortic Aneurysm: An undetected or unmonitored aortic aneurysm that dissects or ruptures is almost always catastrophic. Failure to screen high-risk patients or to refer after incidental imaging findings are common liability scenarios.

Why Mark David Shirian P.C. Handles These Cases the Way It Does

Mark David Shirian P.C. was founded in 2016 with a single purpose: to help people who have been wronged. Personal injury, including medical malpractice and delayed diagnosis claims, is a core part of the firm’s practice. Attorneys Mark D. Shirian and Shawn D. Shirian represent clients across New York City and throughout New York State, and the firm has recovered millions of dollars on behalf of injured clients over its history.

What clients describe when they review this firm is a pattern worth noting: close attention to case details, hard work on their behalf, and being kept informed throughout the process. In delayed diagnosis cases, those qualities matter more than in almost any other type of claim. The medical record in these cases can run hundreds of pages. Understanding where the standard of care broke down, and being able to articulate that to a jury in plain terms, requires exactly the kind of thorough preparation that clients report experiencing with this firm. Compassion matters here too. Patients who come to us after a delayed diagnosis have often already been through a harrowing period of treatment that could have been less severe. The firm approaches those situations as a trusted advocate, not just a legal processor.

The firm handles each case with direct attorney involvement. You work with Mark D. Shirian and Shawn D. Shirian, not a paralegal pipeline. For cases this technically demanding, that direct engagement is not a luxury, it is a necessity.

What to Do After a Suspected Delayed Diagnosis in New York

The first thing to do is request your complete medical records from every provider involved in your care, including the one you believe failed you. Under New York law, you are entitled to your records. Get everything: office visit notes, lab results, imaging reports, referral correspondence, and any communications between providers. These records are the foundation of a delayed diagnosis case, and they can also help you and a new provider understand the full picture of what happened to your health.

Do not confront the original provider or ask them to amend your records. Let the record stand as it is. Alterations to medical records are taken extremely seriously in litigation, and an honest, unmodified record often tells the story more clearly than one that has been cleaned up after the fact.

New York’s statute of limitations for medical malpractice claims is generally two and a half years from the date of the malpractice or from the end of a continuous course of treatment with the same provider for the same condition. This is one of the shorter limitations periods in personal injury law, and delayed diagnosis cases can sometimes raise difficult questions about when the clock starts, particularly in cases involving ongoing treatment relationships. Waiting to consult a delayed diagnosis attorney in New York City is a genuine risk, not a hypothetical one. Do not assume you have more time than you do.

New York medical malpractice cases must be supported by a certificate of merit, meaning an attorney must consult with a medical expert before filing suit and certify that a competent expert has reviewed the case and found a reasonable basis for the claim. This is why the firm’s preparation begins long before any complaint is filed. The expert review process, the analysis of the standard of care, and the causation work happen before litigation, not during it. For clients, this means knowing early whether the case has the evidentiary support it needs.

Cases in New York City are typically filed in the Supreme Court of the appropriate county. A Bronx case would be filed in Bronx County Supreme Court; a Manhattan case in New York County Supreme Court; a Brooklyn or Queens case in Kings or Queens County Supreme Court respectively. Each courthouse has its own procedures and medical malpractice case management practices. Having counsel who regularly practices in these venues matters for timelines and local court expectations.

Questions People Ask About Delayed Diagnosis Claims in New York

What is the difference between a delayed diagnosis and a wrong diagnosis for purposes of a malpractice claim?

A misdiagnosis means the provider identified the wrong condition. A delayed diagnosis means the correct condition was eventually found but not in time to prevent additional harm. Both can support a malpractice claim if the error departed from the standard of care and caused injury. The legal analysis differs primarily in how causation is established. In a delayed diagnosis case, you are asking what would have been different if the diagnosis had been made on schedule.

Does every delayed diagnosis give rise to a malpractice claim?

No. A diagnosis delay is only actionable if a reasonably competent physician in that specialty would have made the diagnosis earlier given the available information, and if the delay caused measurable harm beyond what would have occurred with a timely diagnosis. Not every diagnostic miss reflects negligence. Medicine involves uncertainty, and some conditions present atypically. A lawyer reviewing your case will work with medical experts to make that determination honestly.

How do I prove that an earlier diagnosis would have changed my outcome?

This requires expert medical testimony. An oncologist, cardiologist, or specialist in the relevant field will review the records and testify about how the condition progressed during the delay, what treatments were available at the earlier point in time when the diagnosis should have been made, and what the patient’s prognosis looked like then versus what it became after the delay. Survival statistics, treatment guidelines, and clinical literature all factor into this analysis.

Can I sue a hospital, a clinic, or only an individual doctor?

Liability can attach to multiple parties depending on the circumstances. Attending physicians, residents, nurse practitioners, and physician assistants can each be named. Hospitals and medical groups can be liable for the acts of employed staff or, in some cases, for systemic failures like inadequate supervision or understaffing that contributed to the missed diagnosis. The full chain of care needs to be evaluated to identify all potentially liable parties.

What damages can be recovered in a New York delayed diagnosis case?

Recoverable damages include past and future medical expenses, lost wages and reduced earning capacity, pain and suffering, and loss of enjoyment of life. In cases involving a terminal prognosis that would not have existed with a timely diagnosis, the damages can be substantial. New York does not cap compensatory damages in medical malpractice cases, but claims do require careful documentation and expert support to establish the full scope of harm.

What if my doctor is at a public hospital like a New York City Health + Hospitals facility?

Claims against public hospitals or city-operated facilities in New York require a Notice of Claim to be filed within 90 days of the incident before a lawsuit can be commenced. This is a separate and earlier deadline than the general malpractice statute of limitations, and missing it can bar your claim entirely. This is one of the most common procedural mistakes in cases involving public hospitals, and it is one of the strongest reasons to contact a delayed diagnosis attorney quickly rather than waiting.

Will my case settle or go to trial?

Most medical malpractice cases in New York resolve before trial, but that does not mean every case should settle, and it does not mean early offers reflect the actual value of the claim. The strength of your expert testimony, the clarity of the departure from the standard of care, and the documentation of your damages all affect how a case resolves. This firm approaches every case prepared to go to trial, because that preparation is what produces better outcomes whether the case settles or proceeds to verdict.

Can a delayed diagnosis claim be brought if the patient has since died?

Yes. A wrongful death claim can be brought by the decedent’s estate if the delayed diagnosis contributed to the death. New York’s wrongful death statute allows the estate to recover for the decedent’s conscious pain and suffering before death, lost financial support to surviving family members, and related damages. There are separate procedural requirements for wrongful death claims, including who has standing to bring them, that an attorney can walk through with the family.

What if I signed paperwork at the hospital agreeing to something? Does that affect my ability to sue?

Standard hospital intake paperwork and consent forms do not waive your right to bring a malpractice claim. Patients cannot be made to sign away their legal rights to sue for negligence as a condition of receiving care. If you signed something specific that you are concerned about, an attorney can review that document and tell you whether it has any legal effect on a delayed diagnosis claim.

How long does a delayed diagnosis case typically take in New York courts?

Medical malpractice cases in New York’s Supreme Court generally take two to four years from filing to trial or resolution, depending on the county, the complexity of the medical issues, and the court’s calendar. Cases involving significant damages tend to involve more extensive discovery, including depositions of multiple treating providers and expert witnesses. Counties vary; cases in New York County and Kings County have their own individual timelines based on judge assignment and docket volume. Your attorney can give you a realistic estimate based on where your case would be filed.
