S62.013B Displaced fracture of distal pole of navicular [scaphoid] bone of unspecified wrist, initial encounter for open fracture

Name of the Condition

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

Summary

A displaced fracture of the distal pole of the navicular (scaphoid) bone in the unspecified wrist involves a break in the small bone near the base of the thumb, with bone fragments shifted out of normal alignment. This is an open fracture, meaning the bone has pierced the skin, and it is the initial encounter for treatment. The scaphoid plays a key role in wrist stability, and this type of fracture may require specific management to address both the displacement and the open nature of the injury.

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 events that cause the bone to break and displace, with the fracture line extending through the skin.

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.
• Visible wound or open skin at the fracture site.
• Possible numbness or tingling if nerves are affected.

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility, with attention to the open wound. Imaging tests, such as X-rays, CT scans, or MRI, to visualize the fracture, confirm displacement, and evaluate the extent of the open injury. Wound assessment to determine contamination or infection risk.

Treatment Options

• Wound care: Cleaning and dressing the open fracture to prevent infection.
• Immobilization: Wearing a cast or splint to stabilize the wrist and promote healing.
• Surgical intervention: May be required to realign the bone fragments and repair soft tissues, especially if the fracture is severely displaced or the wound is extensive.
• Antibiotics: Administered to reduce the risk of infection due to the open nature of the fracture.
• Pain management: Medications to alleviate discomfort during recovery.

Prognosis and Follow-Up

Healing depends on the severity of the fracture, displacement, and wound condition. Open fractures carry a higher risk of infection and may require longer immobilization or additional procedures. Follow-up appointments are necessary to monitor healing, assess for complications, and adjust treatment as needed. Physical therapy may be recommended to restore wrist function.

Complications

• Infection at the open wound site.
• Delayed union or nonunion of the fracture.
• Nerve or blood vessel damage.
• Arthritis or long-term wrist stiffness.
• Persistent pain or reduced mobility.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., wrist guards in sports).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if balance is impaired.
• Seek prompt treatment for wrist injuries to prevent complications.

When to Seek Professional Help

• If the wrist is severely painful, swollen, or deformed.
• If there is an open wound or bleeding at the injury site.
• If numbness, tingling, or loss of circulation occurs.
• If symptoms worsen or do not improve with initial care.

Tips for Medical Coders

Document the fracture type (displaced), bone involved (distal pole of navicular [scaphoid]), wrist side (unspecified), encounter type (initial), and fracture nature (open). Include details on wound assessment, imaging findings, and treatment provided to support code assignment. Ensure documentation reflects the open fracture and initial encounter to align with the code's specificity.
