About New York-Presbyterian Hospital

NewYork-Presbyterian Hospital (NYP) is one of the most prestigious academic medical centers in the United States. Affiliated with both Weill Cornell Medicine and Columbia University Vagelos College of Physicians and Surgeons, NYP operates multiple campuses across New York City, including:

• NewYork-Presbyterian/Weill Cornell Medical Center — Upper East Side, Manhattan
• NewYork-Presbyterian/Columbia University Irving Medical Center — Washington Heights, Manhattan
• NewYork-Presbyterian Allen Hospital — Inwood, Manhattan
• NewYork-Presbyterian Lower Manhattan Hospital
• NewYork-Presbyterian Brooklyn Methodist Hospital
• NewYork-Presbyterian Queens

As a major teaching hospital, NYP has residents and fellows involved in patient care at every level. As a tertiary care center, it receives some of the most complex cases from across the region. With high volume, complex cases, and a multi-campus system, diagnostic errors at NYP can involve intricate questions of supervision, communication, and system-level failures.

Common Diagnostic Errors at NYP

1. Failure to Diagnose Cancer

NYP's cancer programs (including the Herbert Irving Comprehensive Cancer Center at Columbia) are among the nation's best. However, cancer misdiagnosis can occur when:

• Mammograms are misread — Radiologists miss breast cancer on screening or diagnostic mammograms
• CT scans are misinterpreted — Lung, liver, pancreatic, or kidney tumors are missed
• Colonoscopies are incomplete — Polyps or tumors are missed or not biopsied
• Pathology is misread — Biopsy results are misinterpreted, leading to delayed cancer diagnosis
• Abnormal results are not followed up — Patients with abnormal screening results are lost to follow-up
• Referrals are delayed — Primary care providers within the system delay referring patients to oncology specialists

The consequences of a delayed cancer diagnosis can be catastrophic — allowing cancer to progress from a treatable early stage to an advanced, incurable stage.

2. Failure to Diagnose Heart Attack

Despite being a major cardiac center, emergency room errors at NYP can lead to missed heart attack diagnoses — particularly in women, who may present with atypical symptoms such as nausea, fatigue, back pain, or shortness of breath rather than the classic "crushing chest pain."

The standard of care requires an ECG within 10 minutes of arrival, cardiac biomarkers (troponin), and appropriate observation for patients with intermediate risk. Failure to follow these protocols may be negligence.

3. Failure to Diagnose Stroke

NYP is a Comprehensive Stroke Center — but the diagnosis must be made before treatment can begin. Failure to recognize stroke symptoms (particularly in younger patients or those with atypical presentations), failure to obtain a prompt CT scan, or failure to administer tPA within the treatment window may be negligence.

The standard of care for suspected stroke includes:

• Rapid triage — Stroke is a time-critical emergency
• NIH Stroke Scale — A standardized neurological assessment
• Non-contrast CT scan — To rule out hemorrhage
• CT angiography — To identify the clot location
• tPA administration — Within 4.5 hours of symptom onset (where indicated)
• Mechanical thrombectomy — For large vessel occlusions, within 24 hours

4. Failure to Diagnose Sepsis

Sepsis is a leading cause of death in hospitals. Failure to recognize the signs of sepsis (fever, tachycardia, hypotension, altered mental status, elevated lactate), failure to obtain blood cultures, or delay in starting antibiotics within 1 hour may be negligence.

5. Failure to Diagnose Pulmonary Embolism

Pulmonary embolism (PE) is a life-threatening condition that is frequently misdiagnosed as pneumonia, asthma, anxiety, or musculoskeletal chest pain. The standard of care requires risk stratification (Wells Score), D-dimer testing, and CT pulmonary angiography (CTPA) when indicated.

6. Failure to Diagnose Aortic Dissection

Aortic dissection — a tear in the wall of the aorta — is a surgical emergency that is frequently misdiagnosed as a heart attack or musculoskeletal chest pain. The standard of care for suspected dissection includes a CT angiogram of the chest. Failure to consider dissection in a patient with severe, tearing chest pain may be fatal.

Radiology and Pathology Errors at NYP

Radiology Errors

NYP's radiology departments handle an enormous volume of imaging studies. Common errors include:

• Misread mammograms — Missing breast cancer on screening mammography
• Misread CT scans — Missing tumors, hemorrhage, or other abnormalities
• Misread MRIs — Missing brain or spinal cord abnormalities
• Failure to compare — Not comparing current imaging with prior studies
• Communication failures — Critical findings (e.g., "incidentaloma") not communicated to the treating physician or patient

Pathology Errors

NYP's pathology departments interpret biopsies, cytology, and surgical specimens. Errors include:

• False negative — Missing cancer on a biopsy (the most dangerous error)
• False positive — Diagnosing cancer when it is not present
• Misclassification — Grading or staging cancer incorrectly
• Communication failures — Critical pathology results not communicated promptly

[Link to: /medical-malpractice/pathology-errors]

Emergency Room Diagnostic Failures

NYP's emergency departments (including the Weill Cornell and Columbia ERs) are among the busiest in New York City. Common ER diagnostic failures include:

• Premature discharge — Sending a patient home before the diagnosis is established
• Failure to order tests — Not ordering ECG, troponin, CT, or other indicated tests
• Failure to consult specialists — Not consulting surgery, cardiology, neurology, or other specialists
• Anchoring bias — Latching onto the first diagnosis and failing to consider alternatives
• Triage errors — Assigning a low triage priority to a patient with a serious condition

Mid-Level Provider Errors

As a large healthcare system, NYP employs physician assistants (PAs) and nurse practitioners (NPs) in emergency rooms, clinics, and hospital wards. Diagnostic errors by mid-level providers — and failure to consult supervising physicians — are a growing source of malpractice claims.

Teaching Hospital Liability and Supervision

As a teaching hospital affiliated with two medical schools, NYP has residents and fellows involved in patient care at every level. Under 10 NYCRR § 405.4, attending physicians must provide appropriate supervision of residents. Key requirements:

• Attending availability — The attending must be immediately available
• Participation in critical portions — The attending must participate in key diagnostic and treatment decisions
• Supervision of residents — The attending is responsible for the resident's actions

Ghost surgery — where a resident performs a procedure without adequate attending supervision — is a recognized problem at teaching hospitals.

Who Can Be Held Liable?

In a diagnostic error case at NYP, potential defendants include:

• The attending physician — For diagnostic errors, failure to order tests, or failure to consult specialists
• The resident or fellow — If they failed to recognize the condition (though the attending is responsible for supervision)
• The radiologist — For misinterpreting imaging studies
• The pathologist — For misinterpreting biopsy results
• The PA or NP — For diagnostic errors and failure to escalate
• NewYork-Presbyterian Hospital — For staffing, credentialing, protocol, and supervision failures

Multi-Campus Complexity

NYP operates multiple campuses. Liability may involve questions of which campus provided care, which providers were employed vs. had privileges, and how the multi-campus system communicated and coordinated care.

Statute of Limitations and Legal Deadlines

NewYork-Presbyterian is a private, nonprofit hospital:

• No notice of claim required — Unlike NYC Health + Hospitals facilities
• CPLR 214-a — 2.5 years from the date of the malpractice
• Continuous treatment doctrine — May extend the deadline if you continued receiving treatment from the same provider for the same condition

Preserving Evidence at NYP

Critical evidence includes:

1. Emergency room or clinic records — Documenting the evaluation and diagnostic workup
2. Imaging studies and radiology reports — What was ordered, what was reported
3. Pathology reports — For biopsy and cytology results
4. Lab results — Blood tests and cultures
5. EMR audit trail — Electronic log of who accessed or modified records (NYP uses Epic)
6. Referral and consult notes — Whether specialists were consulted

Your attorney should send a formal preservation letter to NYP immediately to prevent the destruction or alteration of records.

Frequently Asked Questions

Can I sue NewYork-Presbyterian for misdiagnosis?

Yes. If a physician, radiologist, pathologist, or mid-level provider at NYP failed to diagnose your condition — and this caused you harm — you may have a malpractice claim against both the individual provider and the hospital.

How long do I have to sue NYP?

Under CPLR 214-a, the deadline is generally 2.5 years from the date of the malpractice. The continuous treatment doctrine may extend this if you continued receiving treatment from the same provider for the same condition.

Is NewYork-Presbyterian a public or private hospital?

NewYork-Presbyterian is a private, nonprofit hospital. No notice of claim is required, and the standard 2.5-year statute of limitations applies.

What if a radiologist at NYP misread my imaging?

You may have a claim against the radiologist and against the hospital. Radiology errors — including misread mammograms, CT scans, and MRIs — are a common source of malpractice claims.

What if my cancer was missed at NYP?

If cancer was missed due to misread imaging, misread pathology, failure to follow up on abnormal results, or delay in referral, you may have a malpractice claim. The key question is whether earlier diagnosis would have changed the outcome.

What evidence do I need for a diagnostic error case at NYP?

Medical records, imaging studies and radiology reports, pathology reports, lab results, and the EMR audit trail are the most critical pieces of evidence. Your attorney should send a preservation letter immediately.
