Code Description

ICD-10 Q66.70 is a billable code used to indicate a diagnosis of congenital pes cavus, unspecified foot.

Key Diagnostic Point:

Congenital pes cavus is a foot deformity characterized by an excessive arch, leading to an abnormal foot structure that can affect gait and weight distribution. This condition may arise from various factors, including genetic predispositions or environmental influences during fetal development. Patients with congenital pes cavus may experience discomfort, difficulty in walking, and an increased risk of foot injuries. The condition can be associated with other congenital malformations, particularly those affecting the musculoskeletal system. Diagnosis typically involves a physical examination and may include imaging studies to assess the foot's structure. Treatment options vary based on severity and may include orthotic devices, physical therapy, or surgical intervention. Accurate coding is essential for proper management and reimbursement, particularly in pediatric populations where early intervention can significantly improve outcomes.
