Code Description

ICD-10 Q75.02 is a billable code used to indicate a diagnosis of coronal craniosynostosis.

Key Diagnostic Point:

Coronal craniosynostosis is a congenital condition characterized by the premature fusion of the coronal suture, which runs from ear to ear across the top of the skull. This early closure restricts the growth of the skull perpendicular to the suture, leading to a characteristic head shape that may appear flattened on one side (plagiocephaly) and bulging on the forehead. The condition can result in increased intracranial pressure, developmental delays, and facial asymmetry. 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 prevent complications and support optimal neurodevelopment in affected infants.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between types of craniosynostosis (e.g., coronal vs. sagittal)
  • Understanding associated syndromes (e.g., Apert syndrome, Crouzon syndrome)
  • Documentation of surgical interventions and follow-up care
  • Variability in presentation and severity among patients

Audit Risk Factors

  • Inadequate documentation of the 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

Frequently Asked Questions

What is the importance of documenting associated syndromes in craniosynostosis?

Documenting associated syndromes is crucial as it impacts treatment decisions, prognosis, and the need for multidisciplinary care. Accurate coding ensures appropriate reimbursement and reflects the complexity of the patient's condition.
