S62.0 Fracture of navicular [scaphoid] bone of wrist

Name of the Condition

• Fracture of navicular [scaphoid] bone of wrist

Summary

A fracture of the navicular (scaphoid) bone involves a break in one of the small bones of the wrist, located near the base of the thumb. This bone is critical for wrist stability and movement. Fractures can range from minor cracks to complete breaks and may or may not involve displacement of the bone fragments.

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.

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.

Symptoms

• Pain and tenderness in the wrist, especially at the base of the thumb.
• Swelling and bruising around the wrist area.
• Decreased range of motion 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 determine displacement.

Treatment Options

• Immobilization: Wearing a cast or splint for several weeks to allow healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Surgery: May be required for displaced fractures or if the bone fails to heal (nonunion).

Prognosis and Follow-Up

Most fractures heal with proper immobilization, but healing time can vary (typically 6–12 weeks). Regular follow-up with imaging to ensure proper bone alignment and healing. Physical therapy may be needed to restore strength and range of motion after immobilization.

Complications

• Nonunion (failure of the bone to heal) or malunion (improper healing).
• Avascular necrosis (loss of blood supply to the bone) due to disrupted blood flow.
• Arthritis or chronic pain in the wrist if the fracture is not treated promptly.

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by improving balance and using proper techniques in activities.

When to Seek Professional Help

• Persistent pain, swelling, or bruising after an injury.
• Inability to move the wrist or grip objects.
• Numbness, tingling, or changes in skin color (signs of nerve or blood vessel involvement).

Tips for Medical Coders

• Code S62.0 is used for fractures of the navicular (scaphoid) bone of the wrist. Documentation should specify the fracture type (e.g., displaced, nondisplaced) and encounter details (e.g., initial, subsequent) to ensure accurate coding. Note that additional characters may be required to denote laterality, displacement, or encounter type.
