S62.025G Nondisplaced fracture of middle third of navicular [scaphoid] bone of left wrist, subsequent encounter for fracture with delayed healing

Name of the Condition

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

Summary

This condition involves a break in the middle third of the navicular (scaphoid) bone, a small bone in the wrist near the base of the thumb, on the left side. The fracture is nondisplaced, meaning the bone fragments remain in their normal position. It is documented as a subsequent encounter for treatment, indicating ongoing care for a fracture that has not healed as expected within the typical timeframe.

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

• Persistent 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 evaluate healing progress. Additional assessments may be performed to determine the cause of delayed healing.

Treatment Options

• Continued immobilization with a cast or splint to support the wrist.
• Pain management through medications or other therapies.
• Surgical intervention, if necessary, to stabilize the fracture or promote healing.
• Physical therapy to restore wrist function and strength once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the extent of delayed healing and response to treatment. Regular follow-up appointments are essential to monitor healing and adjust care plans. Full recovery may take longer than typical fractures, and some patients may experience residual stiffness or weakness.

Complications

• Nonunion, where the bone fails to heal properly.
• Avascular necrosis, a loss of blood supply to the bone.
• Chronic pain or reduced wrist mobility.
• Increased risk of future fractures in the affected area.

Lifestyle & Prevention

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

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new symptoms (e.g., numbness, discoloration) develop. Prompt evaluation is important if healing does not progress as expected or if mobility declines significantly.

Tips for Medical Coders

Document the fracture's location (middle third of the navicular bone, left wrist), displacement status (nondisplaced), and encounter type (subsequent for delayed healing). Include details on imaging results, treatment plans, and any factors contributing to delayed healing to support accurate coding.
