Code Description

ICD-10 Q66.02 is a billable code used to indicate a diagnosis of congenital talipes equinovarus, left foot.

Key Diagnostic Point:

Congenital talipes equinovarus, commonly known as clubfoot, is a congenital deformity characterized by an abnormal positioning of the foot. In this condition, the affected foot is turned inward and downward, resembling the shape of a club. The left foot is specifically affected in this code. The etiology of congenital talipes equinovarus is multifactorial, involving genetic predispositions and environmental factors. It is often associated with other congenital malformations, including those of the urinary system such as renal agenesis or bladder exstrophy. Diagnosis is typically made at birth through physical examination, and treatment often involves manipulation and casting, followed by surgical intervention if necessary. Early intervention is crucial for optimal outcomes, as untreated clubfoot can lead to significant functional impairment and disability. The condition may also be part of broader syndromic presentations, necessitating comprehensive evaluation for associated anomalies.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between unilateral and bilateral involvement
  • Potential association with other congenital anomalies
  • Need for precise documentation of foot positioning
  • Variability in treatment approaches and follow-up care

Audit Risk Factors

  • Inadequate documentation of associated congenital anomalies
  • Failure to specify laterality (left vs. right)
  • Misclassification of the severity of the condition
  • Lack of follow-up documentation for treatment outcomes
