Code Description

ICD-10 Q37.1 is a billable code used to indicate a diagnosis of cleft hard palate with unilateral cleft lip.

Key Diagnostic Point:

Cleft hard palate with unilateral cleft lip is a congenital malformation characterized by a split or opening in the hard palate (the bony front part of the roof of the mouth) accompanied by a cleft lip on one side. This condition arises during early fetal development when the tissues that form the lip and palate do not fully come together. The severity of the cleft can vary, affecting feeding, speech, and dental development. Children with this condition may also be at risk for associated congenital anomalies, particularly those affecting the respiratory system, such as choanal atresia, which is a blockage of the nasal passage, and tracheoesophageal fistula, an abnormal connection between the trachea and esophagus. Lung hypoplasia, or underdeveloped lungs, can also occur due to associated conditions. Early diagnosis and intervention are crucial for managing feeding difficulties and preventing complications, and multidisciplinary care involving pediatricians, surgeons, speech therapists, and geneticists is often required.

  • Variability in associated congenital anomalies
  • Need for multidisciplinary documentation
  • Potential for multiple surgical interventions
  • Differentiation from other cleft conditions

Audit Risk Factors

  • Inadequate documentation of associated conditions
  • Failure to capture all surgical interventions
  • Misclassification of cleft types
  • Lack of detailed feeding and developmental assessments
