S62.024G Nondisplaced fracture of middle third of navicular [scaphoid] bone of right wrist, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of middle third of navicular [scaphoid] bone of right 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 right side. The fracture is nondisplaced, meaning the bone fragments remain in their normal position. This is a subsequent encounter for treatment, indicating the patient has already received initial care, and healing is progressing more slowly than expected.

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 used to determine if healing is delayed.

Treatment Options

• Continued immobilization with a cast or splint to support the wrist.
• Pain management through medications or other therapies.
• Possible surgical intervention if healing does not progress with conservative measures.
• Physical therapy to restore strength and mobility once healing allows.

Prognosis and Follow-Up

Healing may take longer than typical fractures due to delayed union. Regular follow-up appointments are necessary to monitor progress. Most patients recover function with appropriate treatment, though recovery time can vary.

Complications

• Nonunion, where the bone fails to heal properly.
• Avascular necrosis, a loss of blood supply to the bone.
• Chronic pain or stiffness in the wrist.
• Long-term reduced mobility or grip strength.

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-injury care instructions to support healing.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new symptoms (e.g., numbness, discoloration) develop. Contact a provider if the wrist does not improve with treatment or if mobility does not return as expected.

Tips for Medical Coders

Document the subsequent encounter and evidence of delayed healing, such as imaging reports or clinical notes, to support the code. Ensure the fracture is confirmed as nondisplaced and specify the right wrist and middle third of the navicular bone.
