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

Name of the Condition

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

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 healing is delayed, indicating the fracture has not progressed as expected during the normal healing timeline. Evaluation and management focus on addressing the delayed healing process to prevent long-term 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. Delayed healing may result from inadequate immobilization, poor blood supply to the scaphoid bone, or underlying health conditions affecting bone repair.

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 or other factors that impair bone healing
• Delayed initial treatment or non-compliance with immobilization

Symptoms

• Persistent pain and tenderness in the wrist, particularly on the thumb side
• Swelling and bruising around the wrist area that does not improve over time
• Decreased range of motion or difficulty gripping objects
• Possible numbness or tingling if nerves are affected
• Lack of visible healing on follow-up imaging

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 healing progress. Additional tests may be used to check for nerve or ligament damage. Comparison with prior imaging helps determine if healing is delayed.

Treatment Options

• Prolonged immobilization with a cast or splint to stabilize the bone
• Pain management with medications or other therapies
• Surgical intervention, such as bone grafting or fixation, if healing does not progress
• Physical therapy to restore function once healing is underway
• Monitoring with regular imaging to assess healing

Prognosis and Follow-Up

Prognosis depends on the cause of delayed healing and response to treatment. Most fractures eventually heal with appropriate management, but delayed healing may extend recovery time. Follow-up appointments and imaging are essential to monitor progress. Complications like nonunion or avascular necrosis may require additional interventions.

Complications

• Nonunion (failure of the bone to heal)
• Avascular necrosis (loss of blood supply to the bone)
• Chronic pain or arthritis in the wrist
• Nerve damage leading to numbness or weakness
• Reduced wrist function or mobility

Lifestyle & Prevention

• Avoid high-risk activities until fully healed
• Use protective gear during sports or work
• Maintain bone health with proper nutrition and exercise
• Follow immobilization instructions carefully
• Quit smoking to improve bone healing

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility decreases. Contact a healthcare provider if numbness, tingling, or signs of infection (e.g., redness, fever) develop. Prompt evaluation is important if healing does not progress as expected.

Tips for Medical Coders

Use this code for a subsequent encounter when a nondisplaced fracture of the proximal third of the left navicular bone is healing slowly. Document the delayed healing status and any contributing factors. Ensure the encounter is classified as "subsequent" and specify the fracture's location and laterality.
