How Much Can I Sue for Misdiagnosis in Buffalo?

On behalf of Rosenthal Kooshoian & Lennon, LLP
Aug 13, 2025

There is no set amount and no cap in New York. What a misdiagnosis lawsuit is worth depends on the harm the misdiagnosis caused, the difference between the outcome you got and the one a correct, timely diagnosis would have given you. A serious case can reach into the millions, covering medical bills, lost income, future care, and pain and suffering. A minor delay that changed nothing may be worth little.

People want a number, and there isn't one, because the value is tied to the damage, not the mistake. Good news for patients: New York puts no cap on medical malpractice damages. Our Buffalo misdiagnosis lawyers at Rosenthal, Kooshoian & Lennon, LLP value these cases by the real harm done, as part of our broader Buffalo medical malpractice practice.

How Much Can You Sue for a Misdiagnosis?

As much as the harm is worth, with no legal ceiling in New York. The value comes from what the misdiagnosis did to you: the extra surgery, the disease that spread while untreated, the permanent damage, the income you lost, the care you'll need for life. A misdiagnosis that led to a lost limb or a terminal outcome is worth far more than one caught a week late with no lasting effect.

Anyone promising an average number is guessing. These cases run from modest to enormous, and the spread is huge because the harm is what drives it. A delayed cancer diagnosis that dropped someone from curable to terminal is a different universe than a misread that added a month of discomfort. The injury sets the value, every time.

Does New York Cap Misdiagnosis Damages?

No. New York does not cap compensatory damages in medical malpractice cases, including misdiagnosis. Many states limit what you can recover for pain and suffering, sometimes to a few hundred thousand dollars. New York does not. That means a jury can award the full value of the harm, both the economic losses and the human ones, without an artificial ceiling cutting it off.

This matters more than most people realize. In a capped state, a catastrophic injury can be worth the same as a moderate one once the limit kicks in. New York lets the recovery match the harm. For a severe misdiagnosis, a lifetime of care, lost earnings, and profound suffering, that absence of a cap can mean the difference between a fair result and a fraction of one.

What Damages Can You Recover?

Two broad kinds, plus wrongful death when a misdiagnosis is fatal. Economic damages cover the hard costs: medical bills, future treatment, lost wages, and lost earning capacity. Non-economic damages cover pain and suffering, disfigurement, and lost enjoyment of life. If the misdiagnosis caused a death, the family can pursue a wrongful death claim for their losses.

The categories usually include:

  • Past and future medical costs. The added treatment, surgeries, and long-term care the misdiagnosis made necessary.
  • Lost income and earning capacity. Wages lost during treatment, and the future earnings gone if you can't work the same way again.
  • Pain and suffering. The physical pain, the emotional toll, and the loss of the life you had, with no dollar cap in New York.
  • Disfigurement and disability. Permanent scarring, an amputation, or a lasting impairment the delay caused.
  • Wrongful death losses. When a misdiagnosis proves fatal, the compensation available to the surviving family.

A serious misdiagnosis case adds these up over a lifetime, which is how the numbers climb.

What Actually Determines the Value?

Mostly the severity and permanence of the harm. A case is worth more when the misdiagnosis caused a worse and lasting outcome, high medical costs, a big loss of income, or a permanent disability. How clearly the doctor was negligent, and how much the delay changed your prognosis, both push the value up or down. The sicker the misdiagnosis made you, the larger the case.

One idea sits at the center of it: you recover for the harm the misdiagnosis caused, not the underlying illness itself. The question is always the gap. Where would you be if the diagnosis had been right and on time, versus where you actually are? A cancer that would have been caught at stage one and instead hit stage four, that gap is enormous, and so is the case.

What Do You Have to Prove to Win?

That the doctor was negligent and that it hurt you. You have to show the doctor failed to meet the accepted medical standard of care, that a reasonably careful doctor would have made the right diagnosis, and that the misdiagnosis caused you real harm. New York also requires a qualified medical expert to support the case from the start.

Both pieces are essential, and the second one is where cases turn. Proving the standard was breached is one thing. Proving the delay actually changed your outcome is another, and it takes a medical expert to connect them. A misdiagnosis lawsuit is really a battle of expert medicine, which is why these cases are not do-it-yourself projects.

Isn't Every Wrong Diagnosis Malpractice?

No, and this is where many claims stop. Doctors are allowed to be wrong without being negligent. Medicine is uncertain, some conditions hide, and a reasonable, careful doctor can still miss something. It becomes malpractice only when the doctor failed to do what a competent doctor would have done, ordering the obvious test, following up the red flag, and that failure caused harm.

The distinction is everything. A rare disease that mimics a common one, correctly worked up but still missed, may be a tragedy without being a case. A textbook symptom ignored, a clear scan misread, a test never ordered, that starts to look like negligence. Our misdiagnosis lawyers sort the unavoidable miss from the careless one before promising anyone a case.

What If the Misdiagnosis Was Fatal?

Then the family can bring a wrongful death claim. When a misdiagnosis, a missed cancer, a missed heart attack, a missed infection, leads to a death that a correct diagnosis likely would have prevented, the surviving family can recover for the losses that death caused them. These are among the most serious and highest-value misdiagnosis cases.

Losing someone because a treatable condition went unspotted is devastating, and the law gives the family a way to hold the provider accountable. A wrongful death misdiagnosis claim looks at what the family lost and what the patient endured. Our Buffalo misdiagnosis lawyers handle these with the seriousness they demand, and pursue every category the law allows.

How Long Do I Have to File a Misdiagnosis Lawsuit in New York?

Generally about two and a half years from the malpractice, or from the end of continuous treatment for the condition. New York has a special rule for cancer and tumor misdiagnosis that can start the clock when the patient discovers the missed diagnosis instead. Public hospitals carry much shorter deadlines. The safest move is to treat the clock as short.

These deadlines are tighter than the ordinary injury deadline, and they have traps. The cancer discovery rule helps patients whose misdiagnosis wasn't found for years, but it has its own limits. A misdiagnosis at a county or state hospital can require formal notice within about 90 days. Our Buffalo misdiagnosis lawyers pin down which deadline applies immediately, because a missed one ends even a strong case.

How Do Our Buffalo Misdiagnosis Lawyers Handle These Cases?

Our Buffalo misdiagnosis lawyers get the complete medical records, have them reviewed by qualified specialists, and build the case around what a careful doctor should have done and how the delay changed the outcome. From there the work is proving negligence and causation, documenting every economic and human loss, and pressing the misdiagnosis lawsuit toward its full value.

These cases are won with expert medicine and detailed proof of harm. Our misdiagnosis lawyers gather the records and imaging, bring in physicians to establish the standard of care and the lost prognosis, work with economists and life-care planners to calculate the lifetime cost, and confront the hospital's defense team head-on. Most cases resolve through negotiation, but each one is built as if it is going to trial, which is what commands a serious offer.
