S62.035A Nondisplaced fracture of proximal third of navicular [scaphoid] bone of left wrist, initial encounter for closed fracture

Name of the Condition

Nondisplaced fracture of proximal third of navicular [scaphoid] bone of left wrist, initial encounter for closed fracture

Summary

A nondisplaced fracture of the proximal third of the navicular (scaphoid) bone in the left wrist is a break in the upper portion of one of the wrist's small bones, near the base of the thumb, where the bone fragments remain in their normal alignment. This type of fracture typically results from trauma and requires evaluation to ensure proper healing and prevent complications.

Causes

Typically results from a fall onto an outstretched hand (FOOSH), which applies significant force to the scaphoid bone. Can also occur due to direct trauma, such as a blow or impact to the wrist, or twisting injuries during 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 confirm nondisplacement. Additional tests may be used to check for associated soft tissue damage.

Treatment Options

• Immobilization with a cast or splint to stabilize the bone.
• Pain management with nonsteroidal anti-inflammatory drugs (NSAIDs) or other analgesics.
• Follow-up imaging to monitor healing progress.
• Physical therapy to restore strength and range of motion once healing allows.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and follow-up care. Healing time varies but typically ranges from 6 to 12 weeks. Regular follow-up appointments are necessary to assess progress and adjust treatment as needed.

Complications

• Delayed union or nonunion of the fracture.
• Avascular necrosis (loss of blood supply to the bone).
• Post-traumatic arthritis in the wrist.
• Persistent pain or stiffness.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if balance is impaired.
• Perform wrist-strengthening exercises to improve stability.

When to Seek Professional Help

Seek immediate medical attention if experiencing severe pain, swelling, deformity, or inability to move the wrist. Also, consult a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the specific location (proximal third of the navicular bone), laterality (left wrist), and encounter type (initial for closed fracture) to support accurate coding. Include details on fracture displacement status and any associated injuries to ensure comprehensive coding.
