Code Description

ICD-10 Q66.4 is a billable code used to indicate a diagnosis of congenital talipes calcaneovalgus.

Key Diagnostic Point:

Congenital talipes calcaneovalgus, commonly referred to as 'flat foot' or 'calcaneovalgus foot', is a deformity characterized by the foot being positioned in a dorsiflexed and everted position. This condition is typically identified at birth and is often associated with a history of intrauterine positioning. The foot appears to be excessively flexible, and while it may resolve spontaneously in many cases, some infants may require physical therapy or corrective footwear. The condition can be isolated or associated with other congenital anomalies, particularly in the musculoskeletal system. It is crucial for healthcare providers to assess the infant's overall health and any potential associated conditions, such as developmental dysplasia of the hip or other limb deformities. Early intervention can improve outcomes and prevent complications related to mobility and gait. Accurate coding is essential for tracking the prevalence of this condition and ensuring appropriate management strategies are implemented.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiation from other foot deformities such as clubfoot.
  • Potential association with other congenital anomalies.
  • Variability in clinical presentation and severity.
  • Need for multidisciplinary management and follow-up.

Audit Risk Factors

  • Inadequate documentation of associated congenital conditions.
  • Failure to specify the severity of the deformity.
  • Misclassification with other foot deformities.
  • Lack of follow-up documentation on treatment outcomes.

Frequently Asked Questions

What is the typical management for congenital talipes calcaneovalgus?

Management often involves observation, as many cases resolve spontaneously. If the condition is severe or associated with other anomalies, physical therapy or orthotic devices may be recommended.
