What This Code Means

A birth defect where brain tissue bulges through an opening in the front part of the skull.

Coding Tips

•Specify the exact location (frontal region) to distinguish from other encephalocele sites
•Document the size and contents of the sac (brain tissue, meninges, cerebrospinal fluid)

Clinical Significance

Frontal encephalocele involves brain tissue protruding through a defect in the front part of the skull, potentially affecting cognitive development and requiring surgical intervention. This diagnosis indicates significant neurological risk with variable prognosis depending on the amount and type of brain tissue involved.

Documentation Requirements

✓Clear documentation of frontal skull defect with brain protrusion
✓Size and location of encephalocele precisely described
✓Neuroimaging findings showing brain tissue involvement
✓Associated facial or cranial anomalies documented
✓Neurological examination findings
✓Surgical evaluation and treatment plans
✓Presence or absence of hydrocephalus
✓Developmental assessments and prognosis
