S62.023A Displaced fracture of middle third of navicular [scaphoid] bone of unspecified wrist, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of middle third of navicular [scaphoid] bone of unspecified wrist, initial encounter for closed fracture

Summary

This condition involves a displaced fracture in the middle third of the navicular (scaphoid) bone, a small bone in the wrist near the base of the thumb. The fracture is displaced, meaning the bone fragments have shifted from their normal position. The encounter is classified as initial for a closed fracture, indicating no break in the skin.

Causes

Typically results from a fall onto an outstretched hand (FOOSH). Can occur due to direct trauma to the wrist, such as a blow or impact. May also result from twisting injuries or high-impact 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 have compromised bone integrity.

Symptoms

• Pain and tenderness at the base of the thumb.
• Swelling and bruising around the wrist area.
• Limited wrist movement 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 its characteristics (e.g., displacement, location). The initial encounter for a closed fracture is confirmed by the absence of an open wound.

Treatment Options

• Immobilization with a cast or splint to stabilize the bone.
• Pain management with medications.
• Surgical intervention in some cases to realign and stabilize the bone using screws or pins.

Prognosis and Follow-Up

Healing time depends on the severity of the fracture and treatment. Regular follow-up appointments are necessary to monitor healing and adjust treatment as needed. Physical therapy may be recommended to restore wrist function.

Complications

• Delayed union or nonunion of the fracture.
• Avascular necrosis (loss of blood supply to the bone).
• Arthritis in the wrist joint.
• Nerve or tendon damage.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through proper nutrition and exercise.
• Avoid falls by improving balance and using assistive devices if needed.

When to Seek Professional Help

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

Tips for Medical Coders

Document the fracture location (middle third of the navicular bone), displacement status, wrist side (unspecified), encounter type (initial), and fracture type (closed). Ensure clinical notes support the diagnosis and treatment provided.
