What This Code Means

Reduced blood flow to the newborn's brain, which can occur during or after birth and may result in brain damage if severe.

Coding Tips

•Document the severity and timing of the ischemic event (perinatal vs. postnatal) in the clinical record
•Consider coding associated conditions such as hypoxic-ischemic encephalopathy (HIE) if documented separately

Clinical Significance

Neonatal cerebral ischemia represents decreased blood flow to the developing brain, potentially causing permanent neurological damage. This diagnosis indicates high risk for cerebral palsy, developmental delays, and lifelong neurological complications requiring ongoing specialized care.

Documentation Requirements

✓Documentation of reduced cerebral blood flow in newborn
✓Neuroimaging evidence of ischemic changes (MRI, CT, ultrasound)
✓Clinical signs of hypoxic-ischemic encephalopathy
✓Associated risk factors (birth asphyxia, cardiac issues, hypotension)
✓Neurological examination findings
✓Response to therapeutic interventions
✓EEG findings if seizures present
✓Developmental assessments and follow-up outcomes

Excludes 1 — Do NOT code together

Neonatal cerebral infarction (P91.82-)

Commonly Confused Codes

P91.60 — HIE unspecified, more specific ischemic encephalopathy P20.9 — Intrauterine hypoxia unspecified, occurs before birth G93.1 — Anoxic brain damage, not neonatal-specific P91.2 — Neonatal cerebral leukomalacia, specific white matter damage
