S62.032K Displaced fracture of proximal third of navicular [scaphoid] bone of left wrist, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

A displaced fracture of the proximal third of the navicular (scaphoid) bone in the left 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 ongoing evaluation to address healing delays and restore wrist function.

Causes

Direct trauma to the left wrist, such as a fall onto an outstretched hand, is the primary cause. High-impact injuries, including sports-related accidents or motor vehicle collisions, can lead to this type of fracture. Nonunion may develop due to inadequate immobilization, poor blood supply to the scaphoid bone, or infection.

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
• Smoking, which impairs bone healing
• Delayed or inadequate initial treatment

Symptoms

• Persistent pain and swelling in the left wrist, particularly on the thumb side
• Visible deformity or misalignment of the wrist
• Difficulty moving the wrist or gripping objects
• Bruising or 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 check for nerve or ligament damage. Follow-up imaging is often required to monitor healing progress.

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 nonsteroidal anti-inflammatory drugs (NSAIDs) or other medications
• Physical therapy to restore wrist strength and mobility
• Monitoring for signs of infection or further complications

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient health, and treatment adherence. Nonunion may require extended recovery time or additional procedures. Regular follow-up appointments are necessary to assess healing and adjust treatment plans. Long-term monitoring may be needed to prevent arthritis or other complications.

Complications

• Chronic pain or stiffness in the wrist
• Arthritis in the wrist joint
• Nerve damage or reduced sensation
• Infection, particularly if surgery is required
• Reduced wrist function or mobility

Lifestyle & Prevention

• Avoid high-risk activities that may cause wrist injury
• Use protective gear during sports or physical activities
• Maintain bone health through proper nutrition and exercise
• Seek prompt medical attention for wrist injuries to ensure proper treatment
• Follow rehabilitation guidelines to support healing

When to Seek Professional Help

• Persistent or worsening pain, swelling, or deformity
• Inability to move the wrist or grip objects
• Signs of infection, such as redness, warmth, or fever
• Numbness or tingling in the hand or fingers
• Any concerns about healing progress or complications

Tips for Medical Coders

Document the fracture location (proximal third of the navicular/scaphoid bone), laterality (left wrist), and the presence of nonunion. Include details about the encounter type (subsequent) and any contributing factors, such as trauma or delayed healing. Ensure documentation supports the diagnosis and aligns with clinical findings.
