One Of New York’s Most Respected Personal Injury Firms

Can you sue a doctor or hospital for an AI diagnostic error?

On Behalf of | Aug 4, 2026 | Misdiagnosis

Artificial intelligence (AI) now supports patient care in several New York hospitals. It often helps doctors read scans and guides some robotic procedures. When these systems produce faulty output that harms a patient, questions about legal responsibility can become urgent.

If an AI-assisted error made your condition worse, you could have grounds to sue a doctor, hospital or another party. A claim usually depends on proof that negligent care caused the injury. Learning how liability works can help you assess your legal rights.

How can hospital AI use support a malpractice claim?

An AI diagnostic error can support a malpractice claim if medical negligence harms a patient. A wrong result by itself is not enough. You generally must show that a provider departed from accepted medical practice. You must also connect that failure to your worsened condition. That connection often depends on how the hospital used the AI system and how staff responded to its results.

In clinical practice, hospitals often use AI to flag abnormal test results and mark suspicious areas on medical images. Other tools can generate medication alerts, discharge advice or possible diagnoses. Some robotic surgical platforms may use AI to help with planning, navigation or instrument control.

Concerns about these expanding uses have also reached state lawmakers. Pending New York legislation would regulate its use in insurance utilization reviews. The proposal would require software to consider relevant clinical facts. It would also require qualified health care professionals to decide medical necessity. As of Aug. 4, 2026, the bill remains in the Senate Health Committee and does not govern malpractice claims involving diagnostic errors.

Which AI failures are most likely to harm patients?

Automated tools can fail in several ways, leading to delayed or unnecessary care. Problems often arise from the system’s data, its performance or the way doctors use its results. Some of those errors include:

  • Biased training data: A program may learn from data that does not represent all patients. It could then perform poorly for certain races, sexes, ages or rare conditions. A missed disease pattern could delay needed care.
  • System and data errors: Faulty code, corrupted data or an incorrect label could hide an abnormal scan. The system might also assign the wrong risk level. A patient could receive needless treatment or lose valuable time.
  • Excessive reliance: A doctor might follow an AI recommendation without checking the patient’s symptoms, test results and medical history. That choice becomes more dangerous when the output conflicts with clear clinical signs.

An AI system may also issue a correct warning that staff overlooks. In that case, the technology identified the danger. The error then often lies in how the medical team handled that information.

Who can be held liable when AI contributes to an error?

Doctors, hospitals and sometimes software developers could face liability for an AI-related injury. A physician might accept a faulty result or fail to order more tests. To prove malpractice, a patient must establish a departure from accepted medical practice that caused the injury.

A hospital could face direct liability for choosing an unsafe tool or using it beyond its stated purpose. Poor staff training, weak monitoring or policies that direct staff to favor automated findings could also support a claim. Those failures may connect the hospital’s conduct to the clinical error.

A software vendor or device manufacturer might face product liability or negligence claims if a design defect or inadequate warning made the technology unsafe. The available claim may depend on how New York law classifies the tool, its intended use and each party’s control over it.

Does FDA clearance protect a doctor from malpractice?

No, FDA clearance does not automatically protect a doctor from malpractice liability. Clearance may mean that the FDA found the device substantially equivalent to a legally marketed device. It does not determine if a clinician met the standard of care in treating a particular patient.

A physician must still consider the tool’s purpose, limits and warnings. For example, software might find no urgent problem even when symptoms and an earlier scan point to a stroke. A doctor who treats that output as final without further review could depart from accepted medical practice.

What should you do if AI contributed to your medical harm?

Prompt action can protect your health and preserve data that a system update might erase. These three measures address both concerns.

Seek an independent medical opinion

Ask another qualified physician to review your symptoms and test results. Urgent care takes priority when your condition is severe. A second evaluation can record how the illness progressed after the error.

Obtain complete records and preserve digital evidence

Request your full chart, images, medication history and discharge papers. Ask whether the facility maintains audit trails, alert logs, timestamps, software versions and records of overrides. A patient portal download may leave out these details. A formal preservation notice can help prevent a facility or vendor from overwriting technical logs.

Seek legal guidance without delay

An experienced New York medical malpractice attorney can review your clinical history and identify possible defendants. Counsel can identify who may be liable and review a possible vendor claim. Acting early matters because system updates may erase vital data.

A formal preservation notice can help secure those records. This support lets you focus on treatment and recovery while counsel investigates the cause of the error.
