White Plains Medical Malpractice Lawyers | Billy Cooper Law

Representing Patients And Families Across Westchester County, The Bronx, Rockland County & NYC

When you go to a doctor, hospital, or clinic, you’re placing your health—and often your life—in someone else’s hands. You’re entitled to expect competent, careful, professional care. When that trust is broken and medical providers make preventable mistakes, the consequences can be devastating.

At Billy Cooper Law, our White Plains medical malpractice lawyers represent patients and families who have been harmed by negligent medical care. We handle complex, expert-driven cases involving serious injury, permanent disability, and wrongful death. Our goal is simple: hold providers accountable and secure the financial resources our clients need to rebuild their lives.

If you believe substandard medical care caused harm to you or a loved one, we’re here to listen, investigate, and fight for you.

Medical malpractice cases demand attorneys who understand both the legal complexities and the medical science behind these claims. At Billy Cooper Law, our approach is built on decades of combined experience and a track record of meaningful results.

A Legacy of Legal Excellence in Medical Malpractice

Founding partner Marvin A. Cooper has spent over 50 years representing injured New Yorkers. His involvement in drafting Article 51 of the New York Insurance Law in 1973—the No Fault system that transformed injury claims and insurance coverage statewide—reflects a deep understanding of how personal injury law operates at every level.

Lead trial counsel William H. Cooper, recognized by Super Lawyers in 2024 and 2025 and honored as a CLE presenter at the New York State Bar Association, has secured over $41 million in verdicts and settlements for injured clients. His experience includes a $41 million cerebral palsy verdict—representing the kind of life-changing recovery that medical malpractice victims and their families deserve.

When your case requires both institutional knowledge and aggressive courtroom advocacy, you need a firm that brings both to the table.

What Is Medical Malpractice?

Medical malpractice occurs when a healthcare provider fails to meet the accepted standard of care, and that failure causes injury or death. The standard of care is what a reasonably skilled and competent provider in the same field would have done under similar circumstances.

Medical malpractice can involve errors by:

• Doctors and surgeons
• Nurses and nurse practitioners
• Anesthesiologists
• Radiologists and lab technicians
• Pharmacists
• Hospitals, clinics, and urgent care centers

Not every bad outcome is malpractice. But when healthcare professionals ignore warning signs, rush decisions, misread tests, or cut corners, patients pay the price.

Types Of Medical Malpractice Cases We Handle

At Billy Cooper Law, we represent clients in a wide range of malpractice cases, including:

• Medical negligence and healthcare provider failures
• Childbirth and obstetric injuries (birth injuries)
• Misdiagnosis and delayed diagnosis
• Surgical errors
• Medication errors
• Injuries involving defective medical equipment and devices

Each case is different, but they all center on the same core issue: did the medical team follow the standard of care, and if not, did that failure cause harm?

Medical Negligence & Healthcare Provider Failures

Medical negligence is the foundation of most malpractice claims. It occurs when a healthcare provider does something they should not have done—or fails to do something they should have done—given the patient’s condition.

Common examples of medical negligence include:

• Failing to order appropriate tests
• Ignoring abnormal test results
• Misreading imaging or labs
• Discharging a patient too early
• Failing to monitor a patient after surgery
• Not responding to changes in vital signs
• Failing to obtain informed consent

To prove medical negligence, we must show:

• Duty: The provider owed you a duty of care (doctor–patient relationship).
• Breach: The provider failed to act as a reasonably competent professional would have.
• Causation: That failure caused or significantly contributed to your injury.
• Damages: You suffered measurable harm (medical bills, lost income, pain, disability).

These cases are intensive and expert-heavy, which is exactly why you want a firm that does them regularly.

Our Approach To Medical Negligence Cases

• Thorough investigation of records, communications, and timelines
• Consultation with independent medical experts in the relevant specialty
• Clear explanation of what went wrong and why it matters legally
• Aggressive representation in negotiations and at trial when necessary
• Compassionate guidance for you and your family at every stage

Childbirth Injuries & Obstetric Malpractice

Mistakes during pregnancy, labor, and delivery can cause lifelong harm to both mother and child. We handle obstetric malpractice cases involving:

• Failure to monitor fetal distress
• Delayed C-sections despite alarming fetal heart tracings
• Mismanagement of preeclampsia, gestational diabetes, or infections
• Improper use of forceps or vacuum extraction
• Shoulder dystocia errors and excessive traction
• Failure to recognize maternal complications (hemorrhage, uterine rupture, infection)

Injuries to the baby may include:

• Hypoxic-ischemic encephalopathy (HIE)
• Cerebral palsy
• Brachial plexus injuries (Erb’s palsy)
• Skull fractures and brain bleeds
• Spinal cord injuries

Our birth injury attorneys have secured substantial recoveries for families facing the long-term costs of caring for a child with permanent disabilities, including a $41 million cerebral palsy verdict.

Injuries to the mother may include:

• Severe hemorrhage
• Organ damage
• Surgical injuries from C-sections
• Infections and sepsis

These cases require a deep understanding of obstetric medicine and timing—what the providers knew, when they knew it, and what they should have done.

Misdiagnosis & Delayed Diagnosis

A misdiagnosis doesn’t just mean “getting it wrong.” It can mean losing the critical time window where treatment could have prevented permanent harm.

Common misdiagnosis scenarios include:

• Cancer diagnosed far too late
• Heart attack or stroke mistaken for indigestion, anxiety, or migraine
• Infections misdiagnosed or ignored until they become life-threatening
• Pulmonary embolism dismissed as “just shortness of breath”
• Appendicitis or bowel issues misread as minor stomach problems

Our Approach To Misdiagnosis Cases

• Detailed reconstruction of the diagnostic process
• Comparison with what competent providers would have done
• Medical expert analysis on how the delay changed the outcome
• Proof of damages: additional treatment, lost chances, or permanent injury

If earlier, accurate diagnosis would have changed your prognosis, you may have a malpractice claim.

Surgical Errors

Surgery always carries risk—but some outcomes are not “just a risk,” they’re the result of preventable mistakes.

Examples of surgical malpractice:

• Wrong-site or wrong-patient surgery
• Leaving sponges or instruments inside the body
• Severing nerves, vessels, or organs unnecessarily
• Anesthesia errors leading to brain injury or death
• Failure to monitor patients during and after surgery
• Infections caused by poor sterile technique
• Failure to respond to postoperative complications

These errors can lead to:

• Additional corrective surgeries
• Permanent disability
• Organ damage
• Disfigurement
• Wrongful death

Our Approach To Surgical Error Cases

• Review of operative reports, anesthesia records, and postop notes
• Consultation with surgical experts to pinpoint deviations from the standard of care
• Analysis of hospital protocols, time-outs, and checklists
• Aggressive pursuit of full compensation for your injuries and long-term needs

Medication Errors

Medication mistakes can be just as dangerous as surgical errors—and sometimes more subtle.

Types of medication errors:

• Prescribing the wrong medication
• Prescribing the wrong dose
• Dangerous drug interactions ignored
• Giving medication to the wrong patient
• Administering drugs through the wrong route (IV vs oral)
• Failing to account for allergies, kidney function, or other conditions

Harms from medication errors can include:

• Organ failure (liver, kidney, heart)
• Severe allergic reactions and anaphylaxis
• Internal bleeding
• Stroke or heart attack
• Worsening of the original condition

Our Approach To Medication Error Cases

• Review of prescriptions, pharmacy records, and nursing documentation
• Collaboration with pharmacology and medical experts
• Identification of which provider or institution made the error
• Claims for all resulting medical costs, lost income, and pain

Defective Medical Equipment & Devices

Sometimes the problem isn’t the doctor or nurse, but the equipment they relied on. When defective medical devices cause harm, you may have both a malpractice claim and a product liability claim.

Examples of defective medical equipment issues:

• Faulty diagnostic devices leading to wrong readings
• Malfunctioning surgical instruments causing internal damage
• Defective implants (joints, mesh, pacemakers) that fail prematurely
• Infusion pumps or monitors delivering wrong doses or false readings

These cases often involve product liability as well as potential malpractice, meaning we may pursue claims against:

• Device manufacturers
• Distributors
• Hospitals that failed to maintain or remove recalled equipment

Our Approach To Defective Medical Equipment Cases

• Technical investigation with engineers and device experts
• Review of maintenance logs, recall notices, and manufacturer warnings
• Linking the defect directly to your injury
• Pursuit of compensation from all responsible companies and institutions

What Compensation Is Available In A Medical Malpractice Case?

Medical malpractice injuries are often severe and long-lasting. Compensation may cover:

Past and future medical expenses:

• Hospitalization, surgery, ICU care
• Rehabilitation and long-term treatment
• Home health aides and nursing care

Lost income and loss of earning capacity:

• Time missed from work
• Inability to return to your prior occupation
• Reduced future earning potential

Pain and suffering:

• Physical pain and limitations
• Emotional distress, anxiety, and depression
• Loss of enjoyment of life
• Inability to engage in activities you once loved
• Loss of independence and mobility

Wrongful death damages (for families who have lost a loved one):

• Funeral and burial costs
• Loss of financial support and companionship

Every case is different. We work with economists, life-care planners, and medical experts to calculate the full, lifetime impact of malpractice.

How Billy Cooper Law Handles Medical Malpractice Cases

These cases are complex, hard-fought, and heavily defended. That’s why our approach is meticulous and strategic.

1. Free Case Evaluation: We review your medical history, listen to your story, and give you an honest assessment of whether a malpractice claim is worth pursuing.
2. Detailed Record Review: We obtain and analyze your medical records, imaging, lab results, and hospital notes.
3. Expert Consultation: We work with independent specialists to evaluate whether the providers’ care met the standard in their field.
4. Filing The Claim: We bring claims against all responsible parties: doctors, nurses, hospitals, clinics, and sometimes device manufacturers.
5. Negotiation & Litigation: We negotiate aggressively with insurers and defense counsel. If they refuse to be fair, we are ready to go to trial.
6. Support From Start To Finish: We keep you informed, answer your questions, and help you navigate both the legal process and the practical realities of recovery.

Many law firms settle medical malpractice cases quickly because they lack the resources or experience to take cases to trial. At Billy Cooper Law, we prepare every case as if it’s going to trial—because that’s what produces results.

Insurance companies and hospital defense teams know which firms will actually follow through with litigation. Our track record of courtroom success, including a $41 million cerebral palsy verdict secured by lead trial counsel William H. Cooper, sends a clear message: we don’t back down.

This trial-ready approach benefits our clients whether the case settles or proceeds to verdict. Defense attorneys negotiate differently when they know they’re facing a firm that has the resources, expertise, and willingness to see a case through to the end.

Frequently Asked Questions

How long do I have to file a medical malpractice lawsuit in New York?

In New York, you generally have 2 years and 6 months from the date of the malpractice (or from the end of continuous treatment by the same provider) to file a lawsuit. However, there are exceptions, and certain circumstances can extend or shorten this deadline. If your case involves a child or a foreign object left in your body, different rules may apply. Consulting with an attorney promptly ensures you don’t miss critical deadlines.

What if I’m not sure whether malpractice occurred?

That’s exactly why we offer free case evaluations. Many patients suspect something went wrong but aren’t sure whether it rises to the level of malpractice. Our team reviews your medical records and consults with independent medical experts to determine whether you have a viable claim. You don’t need to have all the answers before reaching out.

Can I sue a hospital, or only the doctor who treated me?

Hospitals can be held liable for malpractice in several ways—including the negligence of their employees, failure to maintain proper staffing levels, and failure to enforce safety protocols. We investigate every potential defendant to ensure all responsible parties are held accountable. This may include doctors, nurses, anesthesiologists, technicians, hospitals, clinics, and even medical device manufacturers.

How much does it cost to hire a medical malpractice lawyer?

We handle medical malpractice cases on a contingency fee basis, which means you pay nothing upfront. Our fees come from the settlement or verdict we win on your behalf. If we don’t recover compensation for you, you owe us nothing. This ensures that everyone has access to quality legal representation, regardless of financial circumstances.

What makes medical malpractice cases different from other personal injury cases?

Medical malpractice cases require expert testimony to establish the standard of care and prove that the provider deviated from it. This makes them more complex and expensive to pursue than typical injury cases. Additionally, hospitals and healthcare providers are typically defended by well-funded legal teams. You need attorneys with the resources and experience to match them—and to take your case to trial if necessary.
