Missed Diagnosis in New York? Hold Hospitals Accountable

What Is a Missed Diagnosis?

A missed diagnosis occurs when a healthcare provider fails to identify a patient’s condition in a timely manner, or identifies the wrong condition, leading to delayed or inappropriate treatment. In New York, a viable medical malpractice claim typically requires showing that the provider departed from accepted medical standards and that this departure caused harm. See, for example, the New York Courts overview of medical malpractice (CourtHelp).

Common Causes of Diagnostic Errors

• Communication breakdowns between departments or shifts
• Failure to order or follow up on tests and imaging
• Misinterpretation of radiology or pathology results
• Incomplete history-taking or inadequate physical examination
• Premature closure (settling on a diagnosis without ruling out reasonable alternatives)
• EHR and workflow issues, including lost or delayed results

Who Can Be Held Accountable

Depending on the facts, responsible parties may include:

• Hospitals and health systems for institutional failures, negligent credentialing, or breakdowns in policies and supervision
• Physicians (e.g., emergency, primary care, specialists) for deviations from accepted practice
• Diagnostic professionals (radiologists, pathologists, laboratories) for interpretation or reporting errors
• Other licensed providers involved in triage, testing, or follow-up

Proving a Missed Diagnosis Claim in New York

Most New York medical malpractice cases require expert testimony to establish the applicable standard of care, a departure from that standard, and causation. See Alvarez v. Prospect Hospital and the medical malpractice instructions in the New York Pattern Jury Instructions. There are narrow exceptions (e.g., res ipsa loquitur in obvious-error scenarios); see Kambat v. St. Francis Hosp.

Supporting evidence may include medical records, test orders and results, imaging, pathology slides, referral notes, discharge instructions, audit logs from the electronic health record, and communications showing missed follow-up.

Hospitals’ Duties and System Responsibilities

Hospitals in New York are required to maintain quality assurance and credentialing programs and adopt reasonable policies to promote patient safety. See Public Health Law § 2805-j and § 2805-k. Failures in staffing, supervision, communication systems, or follow-up processes may support claims against the facility, separate from any individual provider’s negligence, depending on the facts.

Notice and Timing Considerations

New York imposes strict deadlines for medical malpractice claims. The general statute of limitations for medical malpractice and the continuous treatment doctrine are addressed in CPLR 214-a. If the defendant is a municipal or public hospital, additional rules may apply, such as notice-of-claim requirements under General Municipal Law § 50-e. Municipal claim procedures are also discussed by the NYC Comptroller. Because deadlines can vary by facts, parties, and institution type, consult counsel promptly to preserve your rights.

The Continuous Treatment Doctrine

Under New York’s continuous treatment doctrine, the time to bring a claim can be measured from the end of an ongoing course of treatment for the same condition. The doctrine is codified in CPLR 214-a and explained in decisions such as McDermott v. Torre and Borgia v. City of New York. Whether it applies depends on the specifics of your care and provider relationship.

Immediate Steps If You Suspect a Missed Diagnosis

• Request and securely save your complete medical records and imaging
• Document a timeline of symptoms, visits, tests, and communications
• Obtain copies of test orders, results, and discharge instructions
• Seek appropriate medical follow-up or a second opinion
• Avoid discussing the matter with insurers or risk managers before consulting counsel
• Speak with a New York medical malpractice attorney as soon as possible
