New York Civil Practice Law and Rules § 214-a provides a 30-month window (from the date of the malpractice or end of treatment) to start a claim, although some exceptions apply. If you suspect you may have a viable claim, call 518-483-1440 or visit this page for immediate guidance. A skilled medical malpractice lawyer can help you determine whether your case meets these crucial legal standards.

Step 1: Understand the Elements of Medical Malpractice

A proper claim requires establishing four elements: duty of care, breach, causation, and damages. In New York, every healthcare provider who agrees to treat you has a duty to act with reasonable skill. When providers act outside these established guidelines, they may be held liable if their error caused your injury. 

Step 2: Collect Relevant Medical Records and Evidence

Successful claims rely on detailed evidence, which includes hospital records, lab reports, and physician notes. The New York State Department of Health affirms your right to obtain copies of your own medical records. Gather these records as soon as possible to determine whether errors occurred. A medical negligence lawyer typically reviews any diagnostic reports, prescriptions, and follow-up notes to identify lapses in care. Always keep a record of dates, medications, and any noteworthy symptoms or changes in your health.

Step 3: Prove Duty of Care

The first element—duty of care—is usually straightforward. You must show that the provider agreed to treat you. For instance, if a physician at a hospital took you on as a patient or if you visited a clinic for routine checkups, that often suffices to establish a formal provider-patient relationship. An experienced NY medical malpractice lawyer will examine registration documents, medical charts, or referral forms to confirm the start of treatment. Once the relationship is confirmed, the law recognizes that a duty of care was owed.

Step 4: Show Breach of That Duty

Next, demonstrate that the provider’s actions failed to align with accepted practices. According to the New York State Unified Court System, a breach occurs when a healthcare provider does something (or fails to do something) that other competent professionals would have handled differently. Missed diagnoses, incorrect medication dosages, and surgical errors are common examples. 

Step 5: Demonstrate Causation

Even if you establish a breach, you must prove that this breach directly caused your injury. Medical records, imaging results, and timelines are critical here. A skilled medical injury lawyer will look for indicators that the harm would not have occurred if the provider had delivered acceptable care. For example, if a patient’s worsening condition was preventable through timely intervention, that strengthens the argument for causation. Keep track of symptoms or complications that appear after potential errors, as this information often proves essential in linking the breach to the harm.

Step 6: Present Evidence of Damages

Damages refer to the losses you sustained because of the negligent act. These can be economic, such as medical expenses and lost wages, or non-economic, like pain and suffering. Courts in New York consider both types, so thorough documentation is crucial. Pay stubs, hospital invoices, and testimonials from mental health professionals may all be relevant.

Step 7: Speak with a Qualified Medical Malpractice Attorney in New York

Proving these elements can be challenging without legal support. Our team at Poissant, Nichols, Grue, Vanier & Babbie, P.C. has years of experience working with malpractice victims. By seeking prompt advice, you preserve evidence and reduce the risk of missing important deadlines.

Step 8: Build a Solid Case for Court or Settlement

Once the lawsuit is filed, each side typically engages in discovery to obtain medical records, depose witnesses, and exchange other evidence. The vast majority of medical malpractice claims settle before reaching a jury, but a trial remains possible. Medical malpractice lawyers in NYC often prepare meticulously for either outcome, as a strong case can encourage a more favorable settlement. A medical negligence lawyer will make sure you fully understand any settlement offers and negotiate on your behalf to secure the compensation you deserve.
