S92.256A Nondisplaced fracture of navicular [scaphoid] of unspecified foot, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of navicular [scaphoid] of unspecified foot, initial encounter for closed fracture

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. Since the fracture is closed and nondisplaced, the skin remains intact, and the bone fragments are not shifted out of position. This condition is usually managed with immobilization and monitoring to ensure proper healing.

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.
• Pain management with medications.
• Rest and elevation to reduce swelling.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Follow-up appointments are typically scheduled to monitor healing progress, often with repeat imaging to confirm bone alignment. Full recovery may take several weeks to months, depending on the individual's overall health and adherence to treatment.

Complications

• Delayed healing or nonunion if the fracture does not mend properly.
• Arthritis in the midfoot due to joint stress.
• Chronic pain or stiffness in the foot.
• Nerve or blood vessel damage in severe cases.

Lifestyle & Prevention

• Wear supportive footwear during activities.
• Use protective gear in high-impact sports.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid overuse or repetitive stress on the feet.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, fever). Persistent pain or swelling after initial treatment may also require evaluation.

Tips for Medical Coders

Document the fracture as nondisplaced and specify it is an initial encounter for a closed fracture. Ensure the foot (unspecified) is clearly noted, and confirm no displacement or open wound is present. Use this code for the first visit related to the injury; subsequent encounters may require different codes.
