S62.033P Displaced fracture of proximal third of navicular [scaphoid] bone of unspecified wrist, subsequent encounter for fracture with malunion

Name of the Condition

Displaced fracture of proximal third of navicular [scaphoid] bone of unspecified wrist, subsequent encounter for fracture with malunion

Summary

A displaced fracture of the proximal third of the navicular (scaphoid) bone in the unspecified wrist involves a break where bone fragments have shifted out of their normal alignment, with malunion indicating incomplete or abnormal healing. This condition typically results from trauma and requires ongoing evaluation to address functional impairment and prevent further complications. The proximal third of the scaphoid is critical for wrist stability, and malunion may affect joint mechanics if not properly managed.

Causes

Direct trauma to the wrist, such as a fall onto an outstretched hand, is the most common cause. High-impact injuries, including sports-related accidents or motor vehicle collisions, can also lead to this fracture. Twisting injuries during activities that stress the wrist may result in displacement, and inadequate initial treatment may contribute to malunion.

Risk Factors

• Participation in contact sports or activities with a high risk of wrist injury
• Osteoporosis or weakened bone density, particularly in older adults
• Previous wrist fractures or ligament damage
• Delayed or improper initial fracture management

Symptoms

• Persistent pain and swelling in the wrist, especially on the thumb side
• Visible deformity or misalignment of the wrist
• Difficulty moving the wrist or gripping objects
• Bruising or tenderness over the scaphoid bone area
• Reduced range of motion or functional impairment

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRI, to confirm the fracture, evaluate displacement, and assess healing status. Additional tests may be used to check for nerve or ligament damage associated with malunion.

Treatment Options

• Immobilization with a cast or splint to stabilize the bone, if needed
• Pain management with medications or physical therapy
• Surgical intervention, such as osteotomy or bone grafting, to correct malunion
• Rehabilitation exercises to restore wrist function and strength

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and response to treatment. Regular follow-up appointments are necessary to monitor healing and functional recovery. Physical therapy may be required to improve mobility and strength. Long-term outcomes may include persistent pain or reduced wrist function if malunion is not adequately addressed.

Complications

• Chronic pain or arthritis in the wrist joint
• Reduced range of motion or functional impairment
• Nerve or ligament damage due to malunion
• Increased risk of future fractures in the affected area

Lifestyle & Prevention

• Avoid high-impact activities that stress the wrist until fully healed
• Use protective gear during sports or activities with wrist injury risk
• Maintain bone health through proper nutrition and exercise
• Follow post-treatment guidelines to support proper healing

When to Seek Professional Help

Seek medical attention if you experience persistent pain, swelling, or deformity in the wrist, or if you notice reduced mobility or function. Early evaluation is important to address malunion and prevent complications.

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture with malunion. Include details about the fracture location (proximal third of the navicular/scaphoid bone), wrist side (unspecified), and evidence of malunion. Ensure clinical documentation supports the diagnosis and treatment provided during the encounter.
