Code Description

ICD-10 Q77.6 is a billable code used to indicate a diagnosis of chondroectodermal dysplasia.

Key Diagnostic Point:

Chondroectodermal dysplasia, also known as Ellis-van Creveld syndrome, is a rare genetic disorder characterized by a combination of skeletal dysplasia and ectodermal anomalies. Clinically, it presents with short stature, polydactyly, and dental abnormalities, alongside congenital heart defects in some cases. The condition arises from mutations in the EVC or EVC2 genes, which are crucial for normal skeletal development. Patients often exhibit limb reduction defects, particularly affecting the forearms and legs, and may also present with scoliosis or hip dysplasia. The musculoskeletal system is significantly impacted, leading to functional limitations and requiring multidisciplinary management. Early diagnosis and intervention are essential to address the associated complications and improve the quality of life for affected individuals.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation among patients
  • Need for genetic testing documentation
  • Potential for associated congenital anomalies
  • Differentiation from other skeletal dysplasias

Audit Risk Factors

  • Inadequate documentation of genetic testing results
  • Failure to document associated congenital anomalies
  • Misclassification of the condition as a non-syndromic malformation
  • Lack of clarity in the clinical presentation
