S62.033K Displaced fracture of proximal third of navicular [scaphoid] bone of unspecified wrist, subsequent encounter for fracture with nonunion

Name of the Condition

Displaced fracture of proximal third of navicular [scaphoid] bone of unspecified wrist, subsequent encounter for fracture with nonunion

Summary

A displaced fracture of the proximal third of the navicular (scaphoid) bone in the unspecified wrist involves a break where bone fragments have shifted out of alignment, with nonunion indicating the fracture has not healed properly during a subsequent encounter. This condition typically results from trauma and requires evaluation to address healing delays and prevent further complications.

Causes

Direct trauma to the wrist, such as a fall onto an outstretched hand. High-impact injuries, including sports-related accidents or motor vehicle collisions, can lead to this fracture. Inadequate initial treatment or poor blood supply to the scaphoid bone may contribute to nonunion.

Risk Factors

• Participation in contact sports or activities with a high risk of wrist injury
• Osteoporosis or weakened bone density
• Previous wrist fractures or ligament damage
• Delayed or inadequate initial fracture management

Symptoms

• Persistent pain and swelling in the wrist, particularly on the thumb side
• Limited wrist mobility or stiffness
• Tenderness over the scaphoid bone area
• Possible clicking or grinding sensations during wrist movement

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRI, to confirm the fracture and evaluate nonunion. Additional tests may be used to assess blood flow or bone healing.

Treatment Options

• Immobilization with a cast or splint to stabilize the bone
• Surgical intervention, such as bone grafting or internal fixation, to promote healing
• Pain management with medications or physical therapy
• Monitoring for signs of infection or further complications

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Regular follow-up with imaging is necessary to assess healing progress. Long-term outcomes may include persistent pain or reduced wrist function if healing is incomplete.

Complications

• Chronic pain or arthritis in the wrist joint
• Reduced wrist mobility or stiffness
• Increased risk of future fractures
• Potential need for additional surgery

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Use protective gear during sports or activities with wrist injury risk
• Maintain bone health through proper nutrition and exercise
• Follow post-treatment guidelines to support healing

When to Seek Professional Help

Seek immediate medical attention if pain worsens, swelling increases, or new symptoms develop. Consult a healthcare provider if wrist function does not improve with treatment or if signs of infection (e.g., redness, fever) occur.

Tips for Medical Coders

Document the fracture's location (proximal third of navicular bone), displacement status, and nonunion during the subsequent encounter. Ensure clinical notes specify the fracture's history and healing status to support accurate coding.
