Short answer: An HIE lawsuit in New York is a medical malpractice claim that a baby’s brain was injured by a lack of oxygen or blood flow around birth because the delivery or newborn team did not follow accepted practice, for example by missing warning signs on the fetal monitor, delaying a needed C-section, or not starting cooling therapy in time. The child’s own claim can last up to 10 years in New York, but parents’ claims and public hospital notices have much shorter deadlines.
This is general information, not legal or medical advice. Follow your child’s medical team first, and speak with a lawyer licensed in your state about your family’s situation.
This guide explains what HIE is, when it may point to substandard care, which records matter, and the deadlines in New York, New Jersey, Pennsylvania and Connecticut.
What is hypoxic-ischemic encephalopathy (HIE)?
HIE is brain injury that happens when a baby’s brain does not get enough oxygen (hypoxia) or blood flow (ischemia) before, during or shortly after birth. Early signs can include low Apgar scores, the need for resuscitation, weak muscle tone and seizures. Doctors confirm it with blood gas tests, a neurological exam and brain MRI.
Effects range from mild to severe. Some children recover well; others develop cerebral palsy, epilepsy, developmental delays or vision and hearing problems that need lifelong care.
Why does cooling therapy matter in HIE cases?
For babies born at 36 weeks or later with moderate to severe HIE, the standard treatment is therapeutic hypothermia, which lowers the baby’s body temperature for 72 hours. The National Institute of Child Health and Human Development reported that cooling started within the first 6 hours of life reduced death and disability in its landmark trial. Because of that window, delivering hospitals are expected to recognize HIE quickly and begin cooling or transfer the baby.
When can HIE be medical malpractice?
Some HIE comes from causes no one could have prevented, such as an infection or a placental problem that started before labor. A malpractice claim generally needs a qualified expert to show that the care fell below accepted practice and that this made the injury worse. Lawyers and medical experts often look at:
- Fetal heart rate monitoring: whether worrying patterns on the monitor were noticed, reported and acted on.
- Timing of delivery: whether a C-section or assisted delivery was delayed after signs of distress.
- Obstetric emergencies: how the team handled a placental abruption, uterine rupture, cord prolapse or shoulder dystocia.
- Newborn care: resuscitation at birth, and whether cooling was started or the baby was transferred in time.
Defense experts often argue the injury happened earlier in pregnancy, so timing evidence is critical.
What records do parents need for an HIE claim?
- The mother’s prenatal, labor and delivery records, including nursing notes and medication times.
- Fetal monitoring strips, the full tracing, not just a summary.
- Cord blood gas results and Apgar scores.
- NICU records, including cooling start and stop times, EEGs and transfer notes.
- Brain MRI reports and images, plus the placenta pathology report if one was done.

What is New York’s Medical Indemnity Fund?
New York created the Medical Indemnity Fund in 2011 to pay future health care costs for children with a birth-related neurological injury caused by malpractice during the delivery admission. A child qualifies through a court-approved settlement or a judgment that finds such an injury. Families should understand how it works before agreeing to any settlement.
What are the deadlines in New York, New Jersey, Pennsylvania and Connecticut?
These summaries are starting points. Parents’ own claims, such as for the child’s medical bills, often have shorter deadlines than the child’s claim, and wrongful death rules apply if a baby dies.
New York
- Filing deadline: generally 2 years and 6 months from the malpractice under CPLR 214-a.
- Child’s claim: extended for infancy under CPLR 208, but capped at 10 years from the malpractice. Parents’ claims are not extended.
- Discovery rule: limited to missed cancer and foreign objects, so it rarely helps in HIE cases.
- Certificate of merit: CPLR 3012-a generally requires the lawyer to certify a physician review.
- Public hospitals: a notice of claim is generally due within 90 days. See our NYC notice of claim guide.
- Wrongful death: generally 2 years from death under EPTL 5-4.1. The Grieving Families Act was vetoed in December 2025 and the 2026 version did not pass.
New Jersey
- Filing deadline: generally 2 years, but under N.J.S.A. 2A:14-2 a child’s claim for injuries sustained at birth must be filed before the child’s 13th birthday.
- Discovery rule: yes, from when the injury and its likely cause were or should have been known.
- Affidavit of merit: under N.J.S.A. 2A:53A-27, generally due within 60 days after the defendant’s answer.
- Wrongful death: generally 2 years from death under N.J.S.A. 2A:31-3.
Pennsylvania
- Filing deadline: generally 2 years under 42 Pa.C.S. § 5524.
- Child’s claim: under the MCARE Act, a minor’s claim generally may be filed until age 20 or 7 years from the act, whichever is later.
- Certificate of merit: under Pa.R.C.P. 1042.3, filed with the complaint or within 60 days.
- Wrongful death: generally 2 years from death.
Connecticut
- Filing deadline: under C.G.S. § 52-584, 2 years from when the injury was or should have been discovered, but no more than 3 years from the act.
- Child’s claim: Connecticut courts have held that a child’s age does not extend the 3-year limit, so birth injury claims need fast action.
- Certificate of good faith: under C.G.S. § 52-190a, with a written opinion from a similar health care provider.
- Wrongful death: under C.G.S. § 52-555, generally 2 years from death and no more than 5 years from the act.
How do you find a lawyer for an HIE case?
HIE claims depend on obstetric, neonatal and neuroradiology experts, so look for a firm that handles birth injury cases regularly. Reading about how Kramer, Dillof, Livingston & Moore handles infant brain injury cases can show what these claims involve. You can compare firms in the Top Lawyers category and on the New York location page, including the Kramer, Dillof, Livingston & Moore profile. No lawyer can promise a result.
Outcome: protect your child’s care and your options
Put your child’s care first. Then request the full maternal and newborn records, write down your timeline, note the shortest deadline that could apply, and have a qualified lawyer and medical experts review whether the HIE was unavoidable or linked to care that fell short.
FAQs
Is HIE always caused by medical malpractice?
No. Some HIE results from events no one could prevent. It may be malpractice when warning signs were missed, delivery was delayed, or newborn care such as cooling therapy fell below accepted practice and made the injury worse.
How long do you have to file an HIE lawsuit in New York?
The child’s claim can generally be filed up to 10 years from the malpractice, but parents’ own claims usually have 2 years and 6 months, and public hospital cases generally need a notice of claim within 90 days.
What evidence matters most in an HIE case?
Fetal monitoring strips, cord blood gases, NICU and cooling records, and brain MRI results are usually central.
Can a settlement pay for my child’s future care?
Often, yes. In New York, a court-approved settlement or judgment for a birth-related neurological injury can enroll the child in the Medical Indemnity Fund for qualifying future health care costs.
