S62.031K Displaced fracture of proximal third of navicular [scaphoid] bone of right wrist, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

A displaced fracture of the proximal third of the navicular (scaphoid) bone in the right wrist, with nonunion, refers to a break where bone fragments have shifted out of alignment and failed to heal properly after an initial injury. This condition requires ongoing medical management to address the nonunion and restore wrist function.

Causes

The fracture typically results from trauma, such as a fall onto an outstretched hand. Nonunion may develop due to inadequate immobilization, poor blood supply to the scaphoid bone, or delayed treatment of the initial injury.

Risk Factors

• Participation in activities with a high risk of wrist trauma
• Osteoporosis or compromised bone health
• Previous wrist injuries or fractures
• Smoking, which impairs bone healing

Symptoms

• Persistent wrist pain, especially with movement or weight-bearing
• Swelling or tenderness around the scaphoid area
• Limited range of motion in the wrist
• Possible clicking or grinding sensations during wrist use

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRI, to confirm nonunion and evaluate fracture alignment. Additional tests may be used to assess blood flow or bone density.

Treatment Options

• Surgical intervention, such as bone grafting or internal fixation, to promote healing
• Prolonged immobilization with a cast or splint
• Physical therapy to restore strength and mobility
• Pain management with medications or other modalities

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Regular follow-up with imaging is necessary to monitor healing. Some cases may require long-term management to address functional limitations.

Complications

• Chronic pain or arthritis in the wrist
• Reduced grip strength or mobility
• Increased risk of future fractures
• Nerve or tendon damage in severe cases

Lifestyle & Prevention

• Avoid high-impact activities that strain the wrist until cleared by a healthcare provider
• Use protective gear during sports or work involving wrist stress
• 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 like numbness or tingling develop. Prompt evaluation is important for managing nonunion and preventing further complications.

Tips for Medical Coders

Document the fracture's location (proximal third of the navicular bone), displacement, and the presence of nonunion. Include details about the encounter type (subsequent) and any surgical or therapeutic interventions. Ensure clinical notes support the diagnosis and align with the code's specificity.
