Code Description

ICD-10 Q75.021 is a billable code used to indicate a diagnosis of coronal craniosynostosis unilateral.

Key Diagnostic Point:

Coronal craniosynostosis unilateral is a congenital condition characterized by the premature fusion of one side of the coronal suture, which runs from the top of the head to the ears. This fusion restricts the growth of the skull on the affected side, leading to an asymmetrical head shape, often referred to as plagiocephaly. The condition can result in facial asymmetry, with the forehead appearing flattened on the affected side and the brow protruding on the opposite side. Associated symptoms may include developmental delays, increased intracranial pressure, and potential visual or hearing impairments. Diagnosis is typically made through physical examination and imaging studies such as CT scans. Treatment often involves surgical intervention to correct the skull shape and allow for normal brain growth. Early diagnosis and management are crucial to minimize complications and support optimal developmental outcomes.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and severity of the condition
  • Need for precise documentation of cranial measurements
  • Potential for associated syndromic conditions
  • Variations in surgical interventions and follow-up care

Audit Risk Factors

  • Inadequate documentation of the specific type of craniosynostosis
  • Failure to document associated conditions or syndromes
  • Incorrect coding of surgical procedures related to treatment
  • Lack of follow-up documentation post-surgery

Specialty Focus

Medical Specialties

Pediatrics

Documentation Requirements

Documentation should include detailed growth measurements, developmental assessments, and any associated comorbidities.

Common Clinical Scenarios

Common scenarios include newborn assessments, referrals for surgical evaluation, and follow-up visits post-surgery.

Billing Considerations

Pediatric coders must be aware of the developmental milestones and potential impacts of craniosynostosis on growth and development.

Genetics

Documentation Requirements

Genetic counseling notes should document family history, potential syndromic associations, and genetic testing results.

Common Clinical Scenarios

Scenarios may include evaluations for syndromic craniosynostosis and discussions regarding recurrence risks in future pregnancies.

Billing Considerations

Genetic coders should consider the implications of genetic syndromes that may present with craniosynostosis, such as Apert or Crouzon syndromes.
