Why Neonatologists Get Sued: The Birth Asphyxia, the Missed Jaundice, and the NICU

By John Mahoney · June 2026 · 8 min read

Neonatology is not a high-frequency specialty, but it is the highest-stakes one. A neonatologist who manages a depressed newborn, a jaundiced term infant, or a 26-week premature baby in the NICU is operating in a setting where a missed window or a delayed recognition can produce a lifetime of total disability — and the damages that follow are the largest in medicine. The result is a specialty where claims are comparatively rare but, when they come, sit at the very top of the severity curve. An attorney who values a neonatology intake the way they value a routine clinic case will badly misprice it in both directions: most files do not survive the causation gauntlet, but the ones that do are catastrophic. This guide explains where neonatology liability actually lives, the cannot-miss failures behind it, and what separates a strong case from a weak one — for plaintiff and defense med-mal attorneys.

The patterns below draw on closed-claims and obstetric-neonatal litigation experience that spans different eras and definitions; treat them as directional, verify against the controlling jurisdiction, and value any individual case on its own record.

The Frequency-and-Severity Reality

By frequency, neonatology claims are not common relative to high-volume specialties, and most newborns who are sick recover or have outcomes that no defensible care could have changed. But neonatology lives in the same litigation neighborhood as obstetrics, and the two are frequently named together: a birth-injury case routinely pulls in the obstetrician, the hospital, the nursing staff, and the neonatologist who managed the resuscitation and the early hours of life. The claim count understates the exposure because the cases that do mature are devastating.

Severity is where neonatology stands apart. Birth-related neurologic injury — hypoxic-ischemic encephalopathy progressing to cerebral palsy — is commonly reported as producing the highest average and highest catastrophic payouts of any condition in medical malpractice, because the damages model is lifetime care for a profoundly disabled child: decades of attendant care, therapy, equipment, lost earning capacity, and pain and suffering, frequently reduced to present value at multi-million-dollar and occasionally eight-figure levels. A single neonatology claim can dwarf an entire year of a clinic specialty's losses. The screening lesson is that the dollar exposure is so large that the entire case turns on causation and timing, not on whether a bad outcome occurred — bad outcomes are common, and most are not negligence.

The Dominant Allegation Types

Neonatology claims cluster around perinatal brain injury, missed time-critical diagnoses, and NICU management, plus a consent-and-communication thread that runs through the most severe files:

• Failure to properly resuscitate / delayed or inadequate resuscitation — the depressed newborn who was not ventilated, intubated, or supported per NRP standards quickly enough, allowing or worsening hypoxic-ischemic injury.
• Failure to recognize and treat hypoxic-ischemic encephalopathy — including missing the therapeutic-hypothermia (cooling) window — the highest-payout allegation, where a coolable HIE infant was not identified and cooled within the narrow time window in which cooling improves outcomes.
• Failure to diagnose and manage neonatal hyperbilirubinemia — jaundice that was not measured, trended, or treated and progressed to acute bilirubin encephalopathy and kernicterus, a classically preventable and indefensible injury.
• Failure to recognize and treat NICU emergencies — necrotizing enterocolitis, sepsis, hypoglycemia, and intraventricular hemorrhage that were caught late.
• Improper ventilator, oxygen, or line management — oxygen-titration injury, complications of mechanical ventilation contributing to bronchopulmonary dysplasia, and central-line complications.
• Screening and follow-up failures — most prominently retinopathy-of-prematurity screening that was not done, not timed, or not followed up, leading to preventable blindness.
• Lack of informed consent / failure to communicate — counseling failures around prognosis, resuscitation decisions, and transfer.

The structural point: by dollars, the perinatal brain-injury claims — asphyxia/HIE and kernicterus — dominate the specialty, and they are causation-and-timing cases. Any intake should be triaged first on whether the alleged failure plausibly altered the outcome within a recognized time window, because that is what the entire valuation rests on.

The Cannot-Miss Conditions and Failures

The conditions and failures that drive neonatology litigation are:

• Hypoxic-ischemic encephalopathy / birth asphyxia — delayed or inadequate resuscitation and the missed cooling window. This is the highest-severity exposure. The recurring failure is a depressed newborn whose resuscitation lagged behind NRP standards, or a candidate for therapeutic hypothermia who met cooling criteria but was not cooled within the window where it changes outcomes.
• Neonatal hyperbilirubinemia progressing to kernicterus. A term or near-term infant whose jaundice was not measured against an hour-specific nomogram, not trended, or not treated with phototherapy or exchange transfusion in time — producing permanent, preventable brain injury.
• Necrotizing enterocolitis — recognition and treatment delay. A premature infant whose feeding intolerance, distension, or bloody stools were not escalated, imaged, or surgically addressed promptly.
• Intraventricular hemorrhage — failures in monitoring and management of the at-risk premature brain.
• Retinopathy of prematurity — screening that was not ordered, not timed to the protocol, or not followed up, allowing preventable, permanent vision loss.
• Neonatal hypoglycemia and sepsis — failure to screen, recognize, and treat low glucose or infection before neurologic injury or deterioration set in.
• Ventilator/oxygen management and bronchopulmonary dysplasia, and central-line complications — procedural and management injuries in the prolonged NICU course.

For the brain-injury side, the single most actionable screening question is the timing question: did a recognized therapeutic window exist (resuscitation tempo, the cooling window for HIE, exchange-transfusion thresholds for bilirubin), and does the record show whether that window was met or missed? A neonatology brain-injury claim very often turns on a clock — minutes for resuscitation, hours for cooling, hours-to-days for bilirubin — rather than on whether the injury is real. For the NICU-management side, the decisive question is whether the recognition-to-escalation sequence (NEC, sepsis, ROP follow-up) matched the standard timeline documented in the chart.

The Contributing Factors That Drive Payouts

Across neonatology closed claims, the recurring contributing factors are:

• Clinical judgment and timing — the costliest factor by far: failure to recognize HIE and act within the cooling window, failure to trend and treat bilirubin before kernicterus, and failure to escalate NEC or sepsis. The high-severity claims live and die here.
• Technical performance and protocol adherence — resuscitation that did not track NRP, ventilator and oxygen mismanagement, exchange-transfusion and line-placement complications, and missed ROP-screening protocols.
• Communication and care coordination — the handoff seam between obstetric delivery, nursery, and NICU; delays in calling the neonatologist; and consult-and-transfer decisions, all of which produce the gap in which a window is missed.
• Systems and staffing — coverage, equipment readiness, and whether the facility had the level of NICU and the cooling or surgical capability the infant needed, raising transfer-timing and on-call questions.
• Documentation — incomplete records of resuscitation times, Apgar and cord-gas values, bilirubin trends against the nomogram, screening orders, and parent counseling that weaken the defense.

Two of these are neonatology-specific levers. The first is the timestamped clock: in an HIE or kernicterus case, the line between a defensible file and a catastrophic paid claim is often whether the record shows the resuscitation tempo, the cooling decision time, or the bilirubin trend — the case is frequently won or lost on the minute-by-minute documentation, not the eventual diagnosis. The second is the multi-defendant seam: because birth-injury cases routinely name obstetrics, nursing, the hospital, and the neonatologist, the apportionment of who controlled the missed window reframes both exposure and defense, and the record's handoff trail decides where the liability lands.

Strong Case vs. Weak Case in Neonatology Malpractice

The same factors grade the file, and the framing is useful to both sides.

What makes a neonatology case strong (plaintiff) / dangerous (defense)

• An infant who met therapeutic-hypothermia criteria for HIE but was not cooled, or was cooled outside the window, with the record showing the timestamps that establish the missed opportunity — a clean timing failure tied to a recognized protocol.
• A term newborn whose jaundice was not measured against an hour-specific nomogram or not treated as bilirubin climbed, progressing to kernicterus — a classically preventable, indefensible injury with a clear causation chain.
• A premature infant whose NEC, sepsis, or ROP screening was caught or followed up late, with documentation showing the symptoms or due-date for screening were present and not acted on.
• Resuscitation that demonstrably lagged NRP standards in a depressed newborn, supported by cord-gas and Apgar evidence linking the delay to the brain injury.

What makes a neonatology case weak (plaintiff) / defensible (defense)

• A documented, protocol-compliant resuscitation and a timely, recorded cooling or treatment decision — the clock met, with timestamps and team notes intact.
• Cord gases, placental pathology, or imaging that point to a pre-labor or genetic/metabolic etiology, breaking the causal link between any alleged neonatal delay and the outcome — the injury was not caused by negligent timing.
• A bilirubin course managed against the nomogram with documented phototherapy or exchange-transfusion decisions, or a parent who declined screening or follow-up.
• An ROP, NEC, or sepsis course where the screening and escalation matched the standard timeline in the chart, framing the bad outcome as the disease, not the care.

Neonatology rewards a causation-first triage. On the brain-injury side, the case lives or dies on the timing clock and on whether the injury was caused by a missed window or by an etiology no care could have changed — the cord gases, the placental pathology, and the imaging matter as much as the standard-of-care narrative. On the NICU-management side, it turns on the recognition-to-escalation timeline and on which defendant controlled the decision. Whichever side you are on, grading the file means building the causation chain to the documented clock and pressure-testing the neonatology, neurology, and OB experts who will carry it.

Bottom Line

Neonatologists do not get sued often, but when they do, the claims sit at the absolute top of the severity curve, because the damages model is a lifetime of total disability. The dollars are dominated by perinatal brain-injury claims — birth asphyxia and HIE with a missed cooling window, and jaundice that progressed to kernicterus — with NEC, sepsis, IVH, ROP-screening, and ventilator and line complications filling out the NICU exposure. The cannot-miss facts are the timestamped resuscitation, the cooling-window decision, the bilirubin trend against the nomogram, and the recognition-to-escalation timeline. Whether you are screening these cases for the plaintiff or defending them, triage first on causation and timing, and grade the file on the documented clock, the handoff seam between obstetrics and the NICU, and the etiology evidence — not on the devastating outcome alone.
