Q70.31 Webbed toes, right foot

Name of the Condition

• Webbed toes, right foot

Summary

Webbed toes, right foot is a congenital condition where two or more toes on the right foot are connected by skin or soft tissue. The fusion may involve partial or complete webbing, and the severity can range from a thin membrane to extensive tissue joining. This condition is present at birth and may affect one or multiple digits on the right foot.

Causes

Webbed toes primarily result from genetic factors that disrupt normal limb development during fetal growth. The condition occurs when the toes fail to separate properly, a process that typically completes by the eighth week of gestation. It can occur as an isolated anomaly or as part of a genetic syndrome, such as Apert syndrome or Poland syndrome.

Risk Factors

• Family history of syndactyly or related genetic conditions.
• Association with certain genetic syndromes that include limb malformations as a feature.

Symptoms

• Fusion of skin between adjacent toes on the right foot.
• Reduced range of motion and dexterity in the affected digits.
• Potential functional impairment, particularly in tasks requiring fine motor skills.

Diagnosis

Diagnosis is typically made through physical examination, which assesses the extent of webbing. Imaging studies, such as X-rays, may be used to evaluate bone involvement and guide treatment planning.

Treatment Options

• Surgical separation: Typically recommended to improve function and appearance.
  • The surgery is usually performed before school age to optimize outcomes.

Prognosis and Follow-Up

Prognosis is generally good with appropriate treatment. Follow-up care may include monitoring for functional improvement and addressing any post-surgical needs. Long-term outcomes depend on the severity of the condition and the success of intervention.

Complications

• Potential for functional impairment if left untreated.
• Possible cosmetic concerns affecting self-esteem.

Lifestyle & Prevention

No specific preventive measures exist, as the condition is congenital. Supportive care, such as adaptive footwear, may help manage symptoms.

When to Seek Professional Help

Consult a healthcare provider if webbed toes cause pain, difficulty walking, or significant functional impairment. Early evaluation is recommended for children to assess treatment options.

Tips for Medical Coders

Document the specific foot (right) and the extent of webbing (e.g., soft tissue only or bone involvement) to ensure accurate coding. Include details about associated genetic syndromes or family history if present, as these may impact code assignment.
