S62.035K Nondisplaced fracture of proximal third of navicular [scaphoid] bone of left wrist, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

A nondisplaced fracture of the proximal third of the navicular (scaphoid) bone in the left wrist is a break in the upper portion of the scaphoid bone where the bone fragments remain in their normal alignment. This code is used for a subsequent encounter when the fracture has failed to heal (nonunion) after an appropriate period. Nonunion indicates the fracture site has not progressed to bony union, requiring further evaluation and management to promote healing or address 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.

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
• Poor blood supply to the scaphoid bone, which can impede healing

Symptoms

• Persistent or worsening pain and tenderness in the wrist, particularly on the thumb side
• Swelling and bruising that may not resolve over time
• Limited 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 confirm the fracture and evaluate nonunion. Additional tests may be used to check for nerve or ligament damage.

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 the effectiveness of treatment. Follow-up imaging and clinical evaluations are necessary to assess healing progress. Long-term management may be required to restore function and prevent future complications.

Complications

• Chronic pain or arthritis in the wrist
• Permanent loss of wrist mobility or strength
• Nerve damage leading to numbness or weakness
• Increased risk of future fractures

Lifestyle & Prevention

• Avoid high-impact activities that strain the wrist until fully healed
• Use protective gear during sports or activities with a risk of falls
• Maintain bone health through proper nutrition and exercise
• Follow medical advice for rehabilitation and activity restrictions

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity in the wrist, or if symptoms worsen despite treatment. Contact a healthcare provider if you notice persistent numbness, tingling, or difficulty moving the wrist.

Tips for Medical Coders

Use this code for a subsequent encounter when the fracture has failed to heal (nonunion) after an appropriate period. Document the fracture's location (proximal third of the navicular bone), laterality (left wrist), and the presence of nonunion to support code assignment. Ensure clinical documentation aligns with the definition of nonunion and subsequent encounter timing.
