Code Description

ICD-10 Q01.2 is a billable code used to indicate a diagnosis of occipital encephalocele.

Key Diagnostic Point:

Occipital encephalocele is a type of neural tube defect characterized by a sac-like protrusion of the brain and its surrounding membranes through an opening in the occipital bone at the back of the skull. This congenital malformation occurs during early fetal development when the neural tube, which forms the brain and spinal cord, fails to close completely. The severity of the condition can vary significantly, depending on the size of the encephalocele and the amount of brain tissue involved. Infants with occipital encephalocele may present with neurological deficits, developmental delays, and other associated anomalies such as hydrocephalus, which is an accumulation of cerebrospinal fluid in the brain. Diagnosis is typically made through prenatal imaging techniques such as ultrasound or MRI, and postnatally through physical examination and imaging studies. Management often involves surgical intervention to repair the defect and may require multidisciplinary care, including neurology, neurosurgery, and rehabilitation services. The prognosis varies widely, with some children achieving normal development while others may face significant challenges.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and severity of the condition
  • Need for multidisciplinary documentation and coding
  • Potential for associated anomalies requiring additional codes
  • Complexity in distinguishing from other neural tube defects

Audit Risk Factors

  • Inaccurate coding of associated anomalies
  • Failure to document the severity of the encephalocele
  • Misidentification of the condition as a different neural tube defect
  • Inadequate documentation of surgical interventions

Frequently Asked Questions

What is the prognosis for a child with occipital encephalocele?

The prognosis varies widely depending on the size of the encephalocele and the amount of brain tissue involved. Some children may develop normally, while others may face significant developmental challenges.
