Code Description

ICD-10 Q75.5 is a billable code used to indicate a diagnosis of oculomandibular dysostosis.

Key Diagnostic Point:

Oculomandibular dysostosis, also known as Treacher Collins syndrome, is a congenital condition characterized by craniofacial abnormalities resulting from the improper development of the first and second pharyngeal arches during embryogenesis. This condition typically presents with features such as underdeveloped facial bones, particularly the mandible and zygomatic bones, leading to a characteristic appearance. Patients may also exhibit hearing loss due to malformations of the middle ear structures. Other associated anomalies can include cleft palate, coloboma of the eyelids, and dental abnormalities. The severity of the condition can vary widely among affected individuals, with some experiencing significant functional impairments while others may have only mild cosmetic concerns. Genetic mutations, particularly in the TCOF1 gene, are implicated in the majority of cases, highlighting the importance of genetic counseling and testing in affected families. Early intervention, including surgical correction of facial deformities and audiological support, is crucial for improving quality of life and functional outcomes.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and severity among patients
  • Need for comprehensive genetic evaluation and documentation
  • Potential for co-occurring congenital anomalies
  • Complexity in distinguishing from other craniofacial syndromes

Audit Risk Factors

  • Inadequate documentation of associated anomalies
  • Failure to include genetic testing results
  • Misclassification of severity or type of dysostosis
  • Lack of multidisciplinary care documentation
