S62.016A Nondisplaced fracture of distal pole of navicular [scaphoid] bone of unspecified wrist, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of distal pole of navicular [scaphoid] bone of unspecified wrist, initial encounter for closed fracture

Summary

A nondisplaced fracture of the distal pole of the navicular (scaphoid) bone in the unspecified wrist involves a break in the lower portion of this small wrist bone without displacement of the bone fragments. This type of fracture typically results from trauma and requires evaluation to determine appropriate management, as the scaphoid plays a key role in wrist stability and movement.

Causes

Typically results from a fall onto an outstretched hand (FOOSH). Can also occur due to direct trauma to the wrist, such as a blow or impact. May involve twisting injuries or high-force activities that stress the wrist.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, particularly in older adults.
• Previous wrist injuries or fractures that may compromise bone integrity.

Symptoms

• Pain and tenderness localized to the wrist, especially near the base of the thumb.
• Swelling and bruising around the wrist area.
• Decreased range of motion or difficulty gripping objects.
• Possible numbness or tingling if nerves are affected.

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRI, to visualize the fracture and determine displacement or specific location.

Treatment Options

• Immobilization: Wearing a cast or splint for several weeks to allow healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Follow-up imaging: Monitoring with repeat X-rays to ensure proper healing.
• Surgical intervention: Rarely required for nondisplaced fractures but may be considered if healing is delayed or complications arise.

Prognosis and Follow-Up

Most nondisplaced fractures of the distal pole of the scaphoid heal well with immobilization and conservative management. Follow-up care is essential to monitor healing progress and ensure the wrist regains full function. Physical therapy may be recommended to restore strength and mobility after the immobilization period.

Complications

• Delayed union or nonunion of the fracture.
• Avascular necrosis (loss of blood supply to the bone).
• Post-traumatic arthritis in the wrist joint.
• Persistent pain or stiffness.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by improving balance and using assistive devices if needed.
• Strengthen wrist muscles through targeted exercises.

When to Seek Professional Help

Seek medical attention if you experience severe wrist pain, swelling, or inability to move the wrist after an injury. Prompt evaluation is important to rule out fractures and prevent complications.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the initial encounter for a closed fracture. Include details about the wrist (unspecified) and the distal pole of the navicular (scaphoid) bone. Ensure documentation supports the absence of displacement and the closed nature of the fracture to accurately assign this code.
