Code Description

ICD-10 Q66.6 is a billable code used to indicate a diagnosis of other congenital valgus deformities of feet.

Key Diagnostic Point:

Congenital valgus deformities of the feet, classified under Q66.6, encompass a range of conditions where the foot is abnormally positioned, leading to an outward angulation at the ankle. This specific code captures cases that do not fall under more common classifications of foot deformities. These deformities can be associated with other congenital malformations, including those affecting the urinary system, such as renal agenesis or bladder exstrophy. The clinical presentation may vary, with some patients exhibiting mild symptoms while others may require surgical intervention. The underlying causes can include genetic factors, environmental influences, or a combination of both. Accurate coding is essential for appropriate management and treatment planning, as well as for understanding the potential for associated conditions. In pediatric patients, early diagnosis and intervention can significantly improve functional outcomes and quality of life.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and severity of the deformity
  • Potential association with other congenital malformations
  • Need for multidisciplinary management involving orthopedics and genetics
  • Documentation of associated conditions and their impact on treatment

Audit Risk Factors

  • Inadequate documentation of associated congenital conditions
  • Failure to specify the severity of the deformity
  • Misclassification of the deformity type
  • Lack of clarity on the treatment plan and outcomes
