Name of the Condition

• Congenital Talipes Calcaneovalgus, Left Foot
• Also known as Calcaneovalgus Foot or Congenital Foot Deformity

Summary

Congenital talipes calcaneovalgus refers to a foot deformity present at birth, where the foot is positioned with the heel downward and the front of the foot bent upward and outward. This condition affects the left foot in cases coded as Q66.42.

Causes

The condition is believed to result from intrauterine positioning, where the baby's foot is pressed against the uterine wall. It is not usually associated with an underlying genetic issue.

Risk Factors

• Most commonly seen in first-born children due to limited space in the uterus.
• Family history of foot deformities may slightly increase the risk.
• Certain maternal factors, like uterine structure anomalies, could play a role.

Symptoms

• Visible deformity at birth with the foot bending upwards and outwards.
• Limited range of motion in the affected foot.
• In severe cases, difficulty in fitting shoes properly as the child grows.

Diagnosis

• Physical examination immediately after birth.
• X-rays or ultrasound in rare cases to rule out any other associated skeletal issues.

Treatment Options

• Most cases resolve on their own with simple stretching exercises as the child grows.
• Physical therapy to improve flexibility and strength.
• In rare, persistent cases, surgical intervention may be necessary to correct deformities.

Prognosis and Follow-Up

• The condition typically has an excellent prognosis with most children developing normal foot function and shape.
• Regular follow-up with a pediatrician or orthopedic specialist to monitor progress and adapt treatment plans as needed.

Complications

• If left untreated in rare severe cases, it may lead to long-term functional issues or abnormal gait.

Lifestyle & Prevention

• Regular stretching exercises can help manage symptoms.
• Preventive measures are challenging as the condition is congenital and not influenced by lifestyle factors.

When to Seek Professional Help

• If the condition does not improve with conservative management.
• Presence of pain or severe mobility restrictions.

Tips for Medical Coders

• Ensure the correct laterality is noted (left foot for Q66.42).
• Verify and document any associated deformities accurately.
• Avoid confusion with similar ICD codes by carefully documenting symptoms and physical exam findings.
