S92.22 Fracture of lateral cuneiform

Name of the Condition

• Fracture of lateral cuneiform

Summary

A fracture of the lateral cuneiform involves a break in the lateral cuneiform bone, one of the three cuneiform bones located in the midfoot. This condition typically results from trauma or overuse and can vary in severity, depending on the extent of the injury and whether the fracture is displaced or non-displaced.

Causes

Typically caused by direct trauma, such as falls, sports injuries, or motor vehicle accidents. Stress fractures may develop from repetitive activities or overuse, particularly in athletes or individuals with high-impact occupations.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Older age due to decreased bone density.
• Previous foot injuries or fractures.
• Improper footwear or inadequate protective gear.

Symptoms

• Swelling and tenderness in the midfoot.
• Pain at the site of the fracture, often worsening with weight-bearing.
• Bruising and possible deformity of the foot.
• Difficulty walking or inability to bear weight.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, CT scans, or MRIs, to visualize the fracture and determine its location and severity.

Treatment Options

• Immobilization using casts or splints to limit movement and promote healing.
• Rest and activity modification to reduce stress on the foot.
• Pain management with medications or other therapies.
• Surgical intervention may be required for displaced or complex fractures.

Prognosis and Follow-Up

Most fractures of the lateral cuneiform heal with appropriate treatment, though recovery time varies based on severity. Follow-up care may include monitoring for healing progress and rehabilitation to restore strength and mobility.

Complications

• Delayed healing or nonunion of the fracture.
• Arthritis or chronic pain in the midfoot.
• Nerve or blood vessel damage in severe cases.
• Long-term mobility issues if not properly managed.

Lifestyle & Prevention

• Wear supportive footwear during physical activities.
• Gradually increase activity intensity to avoid overuse injuries.
• Maintain bone health through proper nutrition and exercise.
• Use protective gear during high-risk activities.

When to Seek Professional Help

Seek medical attention if you experience severe pain, swelling, or inability to bear weight after an injury. Prompt evaluation is important to prevent complications and ensure proper treatment.

Tips for Medical Coders

Document the fracture as "Fracture of lateral cuneiform" (S92.22) when the specific bone is identified. Include details about the fracture type (e.g., displaced, open) and any associated injuries to support accurate coding. Ensure clinical documentation aligns with the ICD-10-CM guidelines for tarsal bone fractures.
