S62.026G Nondisplaced fracture of middle third of navicular [scaphoid] bone of unspecified wrist, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of middle third of navicular [scaphoid] bone of unspecified 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. The fracture is nondisplaced, meaning the bone fragments remain in their normal anatomical position. It is classified as a subsequent encounter for fracture with delayed healing, indicating the injury is not yet fully healed and requires ongoing management.

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 confirm delayed healing. Additional assessments may include evaluating blood flow or bone healing markers if necessary.

Treatment Options

• Continued immobilization with a cast or splint to support healing.
• Pain management with medications or physical therapy.
• Surgical intervention if healing does not progress, such as bone grafting or fixation.
• Regular follow-up imaging to monitor fracture healing.

Prognosis and Follow-Up

Prognosis depends on the extent of delayed healing and adherence to treatment. Follow-up care is essential to assess healing progress and adjust management as needed. Most fractures eventually heal with appropriate care, but recovery may take longer than usual.

Complications

• Nonunion or malunion of the fracture.
• Chronic pain or stiffness in the wrist.
• Nerve damage leading to numbness or weakness.
• Arthritis in the wrist joint over time.

Lifestyle & Prevention

• Avoid high-impact activities until fully healed.
• Use protective gear during sports or activities with fall risks.
• Maintain bone health through proper nutrition and exercise.
• Follow medical advice for gradual return to normal activities.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or movement does not improve. Contact a healthcare provider if numbness, tingling, or signs of infection (e.g., redness, fever) occur.

Tips for Medical Coders

Document the fracture location (middle third of navicular bone), nondisplaced status, and subsequent encounter for delayed healing. Include details on imaging or clinical findings supporting delayed healing. Ensure documentation aligns with the code's specificity for fracture management and healing status.
