S92.151A Displaced avulsion fracture (chip fracture) of right talus, initial encounter for closed fracture

Name of the Condition

• Displaced avulsion fracture (chip fracture) of right talus, initial encounter for closed fracture

Summary

A displaced avulsion fracture (chip fracture) of the right talus is a type of ankle injury where a small piece of bone is pulled away from the talus due to ligament or tendon tension. This fracture is classified as closed (no skin break) and occurs during the initial encounter for treatment. The talus, a key bone in the ankle joint, supports weight-bearing and movement, and displacement may affect joint alignment or stability.

Causes

Direct trauma to the ankle, such as falls, sports injuries, or twisting motions, is the primary cause. High-impact forces or sudden stops can strain ligaments or tendons, leading to bone avulsion. Motor vehicle accidents or repetitive stress in activities like running may also contribute.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer) or activities with ankle twisting risks.
• Osteoporosis or reduced bone density.
• Previous ankle or talus injuries.
• Improper footwear or inadequate protective gear during physical activities.

Symptoms

• Sudden, severe pain in the ankle or foot.
• Swelling and bruising around the injury site.
• Difficulty bearing weight or walking.
• Limited range of motion in the ankle joint.
• Possible deformity or abnormal positioning of the foot.

Diagnosis

A healthcare provider performs a physical examination to assess pain, swelling, and mobility. Imaging tests, such as X-rays, CT scans, or MRIs, confirm the fracture and evaluate displacement. Documentation notes the fracture as closed and the initial encounter for treatment.

Treatment Options

• Immobilization with casts or splints to stabilize the fracture.
• Pain management through medication or other interventions.
• Physical therapy to restore mobility and strength post-healing.
• Surgical intervention may be necessary for severe displacement or instability.

Prognosis and Follow-Up

Recovery depends on fracture severity and treatment. Most cases heal with immobilization and therapy, but displaced fractures may require longer healing times. Follow-up imaging and clinical assessments monitor progress and adjust treatment as needed.

Complications

• Chronic pain or arthritis in the ankle joint.
• Nonunion or malunion of the fracture.
• Nerve or blood vessel damage.
• Reduced mobility or long-term instability.

Lifestyle & Prevention

• Wear supportive footwear during physical activities.
• Use protective gear (e.g., ankle braces) in high-risk sports.
• Maintain bone health through diet and exercise.
• Avoid sudden, high-impact movements that strain the ankle.

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, fever). Persistent swelling or limited mobility after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the fracture as displaced, avulsion (chip), right talus, closed, and initial encounter. Ensure clinical notes specify the fracture type, location, and encounter status to support accurate coding.
