Code Description

ICD-10 Q66.12 is a billable code used to indicate a diagnosis of congenital talipes calcaneovarus, left foot.

Key Diagnostic Point:

Congenital talipes calcaneovarus, 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 a 'club' shape. The left foot is specifically affected in this code. The etiology of congenital talipes calcaneovarus is multifactorial, involving genetic predispositions and environmental factors. It is often associated with other congenital anomalies, particularly in the musculoskeletal system. Diagnosis is typically made at birth through physical examination, and imaging studies may be utilized to assess the severity of the deformity. Treatment usually involves non-surgical methods such as the Ponseti method, which includes manipulation and casting, followed by bracing. In some cases, surgical intervention may be necessary to correct the deformity. Early intervention is crucial for optimal outcomes, as untreated clubfoot can lead to functional limitations and pain in later life.
