Q72.23 Congenital absence of both lower leg and foot, bilateral

Name of the Condition

• Congenital absence of both lower leg and foot, bilateral

Summary

Congenital absence of both lower leg and foot, bilateral, is a rare limb reduction defect where the lower leg (tibia and fibula) and foot are missing on both sides. This condition affects mobility and may require medical evaluation and adaptive interventions from birth.

Causes

The exact cause is often unknown but may involve genetic factors, disruptions in fetal limb development, or environmental influences during pregnancy. Vascular issues or amniotic band syndrome can also contribute to limb reduction.

Risk Factors

• Family history of limb abnormalities.
• Maternal exposure to certain medications, chemicals, or infections during pregnancy.
• Genetic syndromes or chromosomal abnormalities.

Symptoms

• Visible absence of both lower leg and foot structures at birth.
• Potential functional limitations affecting movement or balance.
• Possible associated anomalies in other body systems.

Diagnosis

Physical examination immediately after birth to assess limb structure. Prenatal ultrasound may detect limb differences before delivery. Imaging studies (e.g., X-rays) or genetic testing to evaluate severity and rule out syndromes.

Treatment Options

• Prosthetic fitting to improve mobility and function.
• Orthotic devices to support limb alignment.
• Physical therapy to enhance strength and coordination.
• Surgical interventions if needed for associated anomalies.

Prognosis and Follow-Up

Prognosis depends on the severity of the defect and associated conditions. Regular follow-up with orthopedic specialists, physical therapists, and prosthetists is essential to optimize mobility and quality of life. Early intervention improves outcomes.

Complications

• Limited mobility or difficulty with balance.
• Skin breakdown or discomfort from prosthetic use.
• Potential psychological or social challenges related to limb difference.

Lifestyle & Prevention

• Use adaptive equipment (e.g., wheelchairs, walkers) to support daily activities.
• Engage in physical therapy to maintain strength and flexibility.
• Seek support from patient advocacy groups or counseling services.

When to Seek Professional Help

Consult a healthcare provider if there are concerns about limb development during pregnancy or if the infant shows signs of functional limitations after birth. Early evaluation is critical for appropriate management.

Tips for Medical Coders

Document the bilateral nature of the condition clearly in the medical record. Ensure the code Q72.23 is used when the absence of both lower leg and foot is confirmed on both sides. Include details about associated anomalies or syndromes if present, as these may impact coding and reimbursement.
