S92.256 Nondisplaced fracture of navicular [scaphoid] of unspecified foot

Name of the Condition

• Nondisplaced fracture of navicular [scaphoid] of unspecified foot

Summary

A nondisplaced fracture of the navicular (scaphoid) bone in the foot involves a break where the bone fragments remain aligned. The navicular is a tarsal bone in the midfoot, and this type of fracture typically results from trauma or overuse. Nondisplaced fractures may cause pain and swelling but generally do not disrupt the bone’s structural integrity.

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.
• Pain management with medications or other therapies.
• Physical therapy to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Follow-up appointments may be needed to monitor healing and adjust treatment. Full recovery time varies but often ranges from several weeks to months, depending on the individual’s health and activity level.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized.
• Arthritis or chronic pain in the midfoot over time.
• Nerve or tissue damage in severe cases.

Lifestyle & Prevention

• Wear supportive footwear during high-impact activities.
• Gradually increase activity intensity to avoid overuse injuries.
• Maintain bone health through a balanced diet and regular exercise.
• Use protective gear, such as ankle braces, during sports.

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 rule out fractures or other serious conditions.

Tips for Medical Coders

Document the location (unspecified foot) and fracture type (nondisplaced) clearly in the medical record. Ensure the code S92.256 is used when the navicular fracture is confirmed as nondisplaced and the foot is not specified as left or right. Include details about the mechanism of injury and any imaging findings to support the diagnosis.
