V28HCC 201 — Seizure Disorders and Convulsions

0.262

What This Code Means

Seizures or convulsive episodes occurring in newborns, which may be caused by various conditions such as infection, metabolic issues, or birth trauma.

Coding Tips

•Always investigate and document the underlying cause of neonatal seizures, as this may require additional coding
•Distinguish between true seizures and benign sleep myoclonus or jitteriness, which are not coded as convulsions

Clinical Significance

Neonatal convulsions represent serious neurological complications requiring immediate evaluation and treatment. This diagnosis indicates significant risk for developmental delays, cerebral palsy, and long-term neurological sequelae affecting the infant's prognosis.

Documentation Requirements

✓Clear documentation of seizure activity or convulsions in newborn
✓Description of seizure type and characteristics observed
✓EEG findings if performed to confirm seizure activity
✓Underlying etiology identified (hypoxia, infection, metabolic, etc.)
✓Response to anticonvulsant therapy if administered
✓Neurological examination findings
✓Associated complications such as respiratory compromise
✓Follow-up neurological assessments and outcomes

Excludes 1 — Do NOT code together

benign myoclonic epilepsy in infancy (G40.3-)
benign neonatal convulsions (familial) (G40.3-)

Commonly Confused Codes

G40.9 — Epilepsy unspecified, for established seizure disorders beyond neonatal period P91.4 — Neonatal cerebral depression, decreased responsiveness without seizures R56.9 — Unspecified convulsions, not neonatal-specific P91.3 — Neonatal cerebral irritability, hyperexcitability without frank seizures
