S62.034B Nondisplaced fracture of proximal third of navicular [scaphoid] bone of right wrist, initial encounter for open fracture

Name of the Condition

• Nondisplaced fracture of proximal third of navicular [scaphoid] bone of right wrist, initial encounter for open fracture

Summary

A nondisplaced fracture of the proximal third of the scaphoid bone in the right wrist is a break where the bone is cracked but remains in its normal position. This type of fracture occurs during an initial encounter for an open fracture, meaning the skin over the fracture site is broken. Open fractures require prompt medical attention to reduce infection risk and ensure proper healing.

Causes

Direct trauma to the wrist, such as a fall onto an outstretched hand. High-impact injuries, including sports accidents or motor vehicle collisions.

Risk Factors

• Participation in contact sports or activities with a high fall risk
• Osteoporosis or weakened bone structure
• Previous wrist injuries or fractures

Symptoms

• Pain and swelling in the wrist, particularly on the thumb side
• Visible wound or open skin over the fracture site
• Tenderness when pressing on the scaphoid bone area
• Reduced range of motion or difficulty gripping objects

Diagnosis

Physical examination of the wrist for tenderness, swelling, and open wounds. Imaging tests such as X-rays, MRI, or CT scans to confirm the fracture and its nondisplaced nature. Assessment of the open wound for contamination or infection risk.

Treatment Options

• Immediate wound care to clean and dress the open fracture site
• Immobilization with a cast or splint to stabilize the bone
• Antibiotics to prevent infection
• Pain management with nonsteroidal anti-inflammatory drugs (NSAIDs)
• Surgical intervention may be required for severe open fractures or to address soft tissue damage

Prognosis and Follow-Up

With proper treatment, most nondisplaced scaphoid fractures heal within 6–12 weeks. Follow-up appointments monitor healing progress through imaging and physical exams. Open fractures may require longer recovery due to infection risk. Adherence to immobilization and wound care instructions is critical for optimal outcomes.

Complications

• Infection at the open fracture site
• Delayed healing or nonunion
• Arthritis in the wrist joint
• Nerve or blood vessel damage
• Reduced wrist mobility or strength

Lifestyle & Prevention

• Use protective gear during high-risk activities, such as wrist guards in sports
• Maintain bone health through a balanced diet and regular exercise
• Avoid falls by using handrails and wearing appropriate footwear
• Seek prompt medical care for wrist injuries to prevent complications

When to Seek Professional Help

• Severe pain, swelling, or bleeding that does not improve
• Signs of infection, such as redness, pus, or fever
• Numbness, tingling, or loss of circulation in the hand
• Inability to move the wrist or fingers

Tips for Medical Coders

Document the fracture location (proximal third of scaphoid), laterality (right wrist), and encounter type (initial for open fracture). Include details about the open wound, such as size, contamination, or treatment, to support code specificity. Ensure documentation aligns with the ICD-10-CM guidelines for open fractures and nondisplaced bone injuries.
