What is Lavern’s Law? (Civil Practice Law and Rules 214-A)

Lavern's Law is named after Lavern Wilkinson, a Brooklyn woman who tragically died from a curable form of lung cancer after doctors failed to inform her of a suspicious mass on her chest X-ray. Due to the delay in diagnosis, Lavern was unable to seek legal action against the negligent medical providers. Her story highlighted the need for change in New York's medical malpractice laws.

Medical malpractice can have devastating consequences for patients and their families. In New York, a significant step towards protecting patients' rights was taken with the introduction of Lavern's Law. This groundbreaking legislation has reshaped the landscape of medical malpractice cases in the state, providing a beacon of hope for those affected by medical negligence.

What Lavern's Law Does

Lavern's Law is the 2018 amendment to CPLR 214-a that creates a discovery-based statute of limitations for failures to diagnose cancer or malignant tumors, giving patients more time to sue once they learn of the malpractice. It does not change the underlying elements of medical malpractice, and it does not extend deadlines for non-cancer malpractice claims governed by the standard 2½-year rule.

Key Provisions:

  • Provides 2 years and 6 months from when you discovered (or reasonably should have discovered) the negligent failure to diagnose cancer and the resulting injury
  • Alternatively, 2 years and 6 months from the date of last continuous treatment for that condition
  • Subject to a hard cap of 7 years from the date of the malpractice
  • Applies specifically to cancer or malignant tumor misdiagnosis cases

Does It Apply to My Case? Quick Checklist

Ask yourself these three questions:

  1. Was there an alleged negligent failure to diagnose cancer or a malignant tumor? (Not just any medical condition - it must be cancer or a malignant tumor specifically)
  2. When did you first learn, or when should you reasonably have learned, that there was a missed or delayed cancer diagnosis and that it caused harm? (This is your "discovery date")
  3. Has it been less than 2 years and 6 months since that discovery date AND less than 7 years since the alleged malpractice or last continuous treatment?

If you answered "yes" to all three questions, Lavern's Law may apply to your case.

Timeline: What Changed and How Discovery Works

Before 2018

Before Lavern's Law, CPLR 214-a required most medical malpractice actions, including cancer misdiagnosis cases, to be filed within 2 years and 6 months from the date of the negligent act or omission. This meant that even if a patient didn't discover the malpractice until years later, their time to file a lawsuit may have already expired.

After Lavern's Law (Effective January 31, 2018)

Lavern's Law added specific language for failure-to-diagnose cancer or malignant tumors, creating a discovery-based accrual rule with a 7-year outer limit.

Key Timeline Points:

Malpractice Date: The date of the alleged failure to diagnose or treat cancer/malignant tumor

Discovery Date: When you knew or reasonably should have known of the negligent failure to diagnose and the resulting injury (courts focus on discovery of the negligent act, not just the cancer itself)

Filing Deadline: 2½ years from the discovery date or last continuous treatment, but no more than 7 years from the malpractice

Revival Window: The 2018 law included limited revival provisions for certain cancer misdiagnosis claims that became time-barred shortly before the law took effect, allowing them to be filed within six months of the effective date if specific criteria were met

Who Qualifies and How to Self-Screen Quickly

The amended portion of CPLR 214-a applies specifically to "an action based upon the alleged negligent failure to diagnose cancer or a malignant tumor." It does not create a discovery rule for other types of medical malpractice, which remain subject to the standard 2½-year limitations period.

Condition Requirements

Your claim must involve alleged negligent failure to diagnose cancer or a malignant tumor. Other diagnoses, including non-cancerous conditions, fall under general CPLR 214-a rules and do not qualify for Lavern's Law's extended discovery period.

Timing Requirements

You must be within 2½ years of when you knew or reasonably should have known of the negligent failure to diagnose and the resulting injury, AND within 7 years of the malpractice or last treatment. Both conditions must be met.

Age and Special Circumstances

Lavern's Law did not abolish existing tolls (such as infancy) or wrongful-death principles. Those remain governed by separate CPLR provisions and Estates Powers and Trusts Law rules.

Important Note About Benign Tumors and Non-Cancer Malpractice

The statutory text and bill materials refer to cancer and malignant tumors specifically. The operative discovery-rule language in CPLR 214-a is triggered by cancer or malignant tumor, and subsequent case law discusses application in cancer misdiagnosis contexts. Non-cancer malpractice, including misdiagnosis of benign conditions or other diseases, is still governed by the ordinary 2½-year limitations period (with traditional exceptions) rather than Lavern's Law's discovery framework.

What You Must Prove in a Medical Malpractice Claim

Lavern's Law changes when a claim can be filed - it does not change what a plaintiff must prove. New York medical malpractice claims generally require proof of the standard negligence elements as adapted to health care.

What Are the Four Things That Must Be Proven to Win a Medical Malpractice Suit?

Whether your case falls under Lavern's Law or standard medical malpractice rules, you must prove these four essential elements:

1. Duty: A physician-patient or similar professional relationship existed, creating a duty to provide care in accordance with accepted medical standards.

2. Departure (Breach): The provider departed from accepted medical practice. For example, failing to order appropriate tests or follow up on suspicious findings that a reasonably competent provider would have addressed.

3. Causation: The departure was a proximate cause of injury, such as progression of cancer that would likely have been detected and treated earlier absent the negligence. This is often the most challenging element to prove.

4. Damages: You suffered legally cognizable harm, including physical injury, additional treatment, disability, or death.

New York decisions applying Lavern's Law stress that the claim must still meet these malpractice elements. The statute only governs timeliness, not liability standards.

Extension of Statute of Limitations

Before Lavern's Law, patients had only 2.5 years from the date of the alleged malpractice to file a lawsuit. Under the new law, patients with cancer or malignant tumor misdiagnosis cases now have:

  • 2.5 years from the date of discovery of the malpractice or the end of continuous treatment; or
  • 7 years from the date of the alleged malpractice, whichever is earlier.

This extension provides patients with more time to seek justice and compensation for the harm they have suffered.

The Discovery Rule for Cancer Cases

Lavern's Law introduces a discovery rule specifically for cancer cases. In situations where cancer is misdiagnosed or not diagnosed in a timely manner, patients now have the right to file a medical malpractice claim after discovering the misdiagnosis or failure to diagnose. This provision acknowledges the unique challenges faced by cancer patients and ensures they have adequate time to pursue legal action.

Frequently Asked Questions

What is Lavern's Law in New York medical malpractice cases?

Lavern's Law is the informal name for the 2018 amendments to CPLR 214-a that created a discovery-based statute of limitations for medical, dental, or podiatric malpractice actions arising from a negligent failure to diagnose cancer or a malignant tumor. In such cases, a patient has 2 years and 6 months from the date they knew or reasonably should have known of the negligence and resulting injury, or from the last continuous treatment for that condition, but not more than 7 years from the malpractice.

How long do I have to sue for cancer misdiagnosis under Lavern's Law?

In qualifying cancer or malignant-tumor misdiagnosis cases, Lavern's Law allows suit to be commenced within 2½ years from the later of (1) the date of discovery (or when discovery should reasonably have occurred) of the negligent failure to diagnose and injury, or (2) the date of last continuous treatment for the same condition. However, there is a hard cap: no action may be brought more than 7 years after the alleged negligent act or omission.

Does Lavern's Law apply to benign tumors or non-cancer malpractice?

No. The operative statutory language and legislative bill S6800/A8516 address "failure to diagnose cancer or a malignant tumor," and courts analyzing the amendment have applied it in cancer misdiagnosis contexts. Other malpractice claims - including misdiagnosis of benign tumors or non-cancer conditions - remain subject to the standard 2½-year limitations period under CPLR 214-a (measured from the negligent act/omission, with existing exceptions such as continuous treatment and foreign object cases).
