What This Code Means

A newborn's stroke affecting the right side of the brain, caused by blocked blood flow to brain tissue.

Coding Tips

•Confirm documentation specifies the right hemisphere involvement; do not assume laterality without explicit documentation
•Coordinate with imaging reports (MRI/CT) to verify the documented side of infarction

Clinical Significance

Neonatal cerebral infarction affecting the right brain represents acute stroke in newborns, causing tissue death and potential lifelong neurological deficits. This diagnosis indicates high risk for cerebral palsy affecting the left side of the body, developmental delays, and cognitive impairment.

Documentation Requirements

✓Clear documentation of cerebral infarction in newborn
✓Neuroimaging confirming infarct location on right side of brain
✓Clinical signs consistent with stroke (focal weakness, seizures)
✓Timing of infarct occurrence documented
✓Underlying risk factors identified (cardiac, infectious, genetic)
✓Extent and location of brain tissue involvement
✓Response to acute stroke management if applicable
✓Neurological examination findings and laterality
