You were told something happened during delivery, and now your child faces a diagnosis no parent is prepared for. Somewhere between the relief of a birth and the fear of a diagnosis, one question sits underneath everything else: did the medical team cause this, or could nothing have prevented it?
The difference between a birth injury and a birth defect in New York is not just medical language. It often determines whether your family has a malpractice claim at all.
Can I file a medical malpractice claim for a birth injury in New York?
A birth injury is physical trauma caused by how labor and delivery were managed, such as oxygen deprivation from a delayed emergency C-section. A birth defect is a structural or genetic condition that forms earlier in pregnancy, often for reasons unrelated to anyone's care. The distinction matters because only a birth injury caused by a departure from accepted medical care can support a medical malpractice claim in New York.
The Bottom Line:
- A birth injury happens during labor, delivery, or the immediate newborn period, and is often connected to how the delivery was managed. A birth defect forms earlier in pregnancy and frequently has genetic or unknown causes unrelated to the delivery itself.
- According to the CDC, 85 to 90 percent of cerebral palsy cases are congenital, and most of those originate before labor begins, not during a difficult delivery, which means the same diagnosis can point in either direction depending on the facts.
- A malpractice claim requires proof that a provider departed from the accepted standard of care and that the departure, not an unrelated genetic or prenatal cause, caused the injury.
What Is the Difference Between a Birth Injury and a Birth Defect?
A birth injury is physical harm to a baby caused by mechanical or medical complications during labor and delivery: oxygen deprivation from a compressed umbilical cord, trauma from an improperly performed forceps or vacuum extraction, or a fracture from a difficult delivery of a large baby.
A birth defect is a structural or functional abnormality that forms earlier, often during the first trimester, from genetic, chromosomal, or unexplained developmental causes.
Both can result in the same lifelong diagnosis. The difference is timing and cause, which is exactly what a malpractice claim turns on.
- Birth injury: happens during labor, delivery, or shortly after birth; frequently tied to a specific decision or delay by the medical team
- Birth defect: forms during fetal development, often weeks or months before delivery; frequently genetic, chromosomal, or of unknown origin
- Shared ground: some conditions, including certain brain injuries, can result from either a birth injury or a birth defect, which is why the medical record and delivery timeline matter so much
Why Cerebral Palsy Is the Condition Parents Ask About Most
Cerebral palsy sits at the center of this question more than any other diagnosis, because it can result from either a prenatal condition or a labor and delivery complication. According to the CDC, 85 to 90 percent of cerebral palsy is congenital, meaning it relates to events before or during birth, and most of those events happen during pregnancy rather than in the delivery room itself.
Oxygen deprivation at birth, once assumed to be the leading cause, is now understood to account for a smaller share of cases than previously believed.
That does not mean a delivery-related cause is rare or hard to prove. It means the specific timeline of your child's labor and delivery, not the cerebral palsy diagnosis alone, is what a medical review focuses on.
What Causes a Birth Injury During Labor and Delivery?
Birth injuries generally trace back to how a specific complication was managed once it appeared, not to genetics or bad luck. The medical team's response, and how quickly they responded, is usually the central question.
- Failure to recognize or act on signs of fetal distress on the monitor
- Delay in ordering or performing an emergency C-section when one was medically indicated
- Improper use of forceps or a vacuum extractor, causing head trauma or nerve damage
- Failure to diagnose or manage shoulder dystocia, leading to Erb's palsy or a fracture
- Failure to monitor or treat maternal conditions such as preeclampsia that affect the baby's oxygen supply
- Medication errors, including incorrect dosing of labor-inducing drugs
What Causes a Birth Defect, and Can It Still Be Malpractice?
Most birth defects form early in pregnancy and have genetic, chromosomal, or unknown causes that no delivery room decision could have changed. The CDC attributes most birth defects to a complex mix of genetic, behavioral, and environmental factors that researchers do not fully understand, and notes that a birth defect sometimes appears even when the mother has none of the known risk factors.
A birth defect itself is usually not malpractice. But the medical care surrounding it sometimes is, and these are the situations worth having reviewed:
- Failure to order or properly interpret prenatal screening or diagnostic testing that would have detected a treatable condition
- Failure to refer a high-risk pregnancy to a maternal-fetal medicine specialist
- Prescribing a medication known to cause birth defects during pregnancy without adequate warning
- Failure to monitor a known condition closely enough to allow for early intervention after birth
In these situations, the malpractice claim is not that the defect itself was caused by negligence. It is that a provider's failure to detect, disclose, or respond to it caused additional, avoidable harm.
Do I Have a Medical Malpractice Claim for My Child's Birth Injury?
You may, if a qualified physician reviewing the case concludes that a member of the medical team departed from the accepted standard of care and that departure caused or worsened your child's injury. New York requires this kind of physician review, called a certificate of merit, before a malpractice lawsuit can even be filed.
A medical malpractice claim generally requires proof of four things:
- A doctor-patient relationship existed between the mother, the child, or both and the provider.
- The provider departed from the accepted standard of care for the situation.
- That departure, and not an unrelated genetic or prenatal cause, caused the injury.
- The injury resulted in real, documented damages.
Causation is almost always the hardest element in a birth injury case, because the defense will argue the injury was inevitable regardless of the delivery. This is why the fetal heart monitor strips, the timeline between decision and delivery, and the physician review matter more than the diagnosis itself.

How Long Do I Have to File a Birth Injury Claim in New York?
Longer than most malpractice deadlines, because New York pauses the clock while the injured person is a minor. For most children, this means the malpractice statute of limitations does not begin running until the child turns 18, though the claim must still be brought within ten years of the negligent act, whichever comes first for older children. Parents can, and generally should, bring the claim well before that outer limit while records and witnesses are still available.
- If the birth happened at a private hospital: the standard medical malpractice deadlines apply once the child turns 18, subject to the ten-year outer limit
- If the birth happened at a public hospital, including any NYC Health and Hospitals facility: a notice of claim is still required within 90 days, regardless of the child's age, so families should not wait
- Evidence quality does not wait for a legal deadline: fetal monitor strips, nursing notes, and the memories of everyone involved are strongest in the months after delivery, not years later
Frequently Asked Questions About Birth Injuries and Birth Defects in New York
Can cerebral palsy be caused by a birth injury even though it is often genetic?
Yes. Cerebral palsy is a description of the outcome, permanent difficulty with movement and posture, not a description of the cause. The same diagnosis can result from a prenatal condition that had nothing to do with the delivery, or from an intrapartum event such as prolonged oxygen deprivation during labor. A physician review of the specific delivery timeline, not the diagnosis alone, determines which applies.
What if my doctor told me the injury was unavoidable?
That statement is common, and it is not the final word. Physicians and hospitals often describe an outcome as unavoidable before any independent review of the medical records has taken place. An independent physician reviewing the fetal monitor strips, delivery notes, and timeline may reach a different conclusion, particularly around how quickly the team responded to warning signs.
Does a difficult or prolonged labor by itself prove malpractice?
No. A long or difficult labor happens for many reasons unrelated to negligence, including the baby's position and the mother's anatomy. What matters is how the medical team responded once complications appeared: whether they monitored appropriately, recognized distress, and acted within the time a reasonably careful provider would have.
Can I bring a claim if my child was diagnosed months or years after birth?
Often, yes. Many birth injuries, particularly milder cases of cerebral palsy or developmental delays connected to oxygen deprivation, are not fully diagnosed until months or years after delivery. Because New York pauses the malpractice deadline during a child's minority, a late diagnosis does not necessarily mean the claim is time-barred, though the birth and hospital records should be secured and reviewed as early as possible.
