S62.026S Nondisplaced fracture of middle third of navicular [scaphoid] bone of unspecified wrist, sequela

Name of the Condition

• Nondisplaced fracture of middle third of navicular [scaphoid] bone of unspecified wrist, sequela

Summary

This condition represents a healed or healing nondisplaced fracture of the middle third of the navicular (scaphoid) bone in the wrist, classified as a sequela. The fracture is no longer acute, and the bone fragments remain in their normal anatomical position. The scaphoid, a small bone critical for wrist stability, may show residual effects from the prior injury, such as altered biomechanics or chronic symptoms. Sequela indicates the condition is a late effect of the original fracture.

Causes

The fracture originated from an initial injury, typically a fall onto an outstretched hand (FOOSH), direct wrist trauma, or twisting forces. The sequela phase reflects the body’s response to the healed fracture, where residual changes may persist due to the bone’s role in wrist function.

Risk Factors

• Prior wrist injuries or fractures that may have compromised bone integrity.
• Osteoporosis or weakened bone structure, particularly in older adults.
• High-impact activities or occupations involving repetitive wrist stress.

Symptoms

• Chronic pain or tenderness at the base of the thumb.
• Mild swelling or stiffness in the wrist.
• Reduced wrist mobility or grip strength.
• Possible numbness or tingling if nerves were affected during the original injury.

Diagnosis

Physical examination to assess residual pain, swelling, and wrist mobility. Imaging tests, such as X-rays or MRI, to evaluate bone healing and identify any persistent structural changes. Clinical history confirming the prior fracture and its timeline is essential for diagnosis.

Treatment Options

• Conservative management, including activity modification and pain relief.
• Physical therapy to restore wrist function and strength.
• Monitoring for delayed healing or complications, such as avascular necrosis.

Prognosis and Follow-Up

Most nondisplaced scaphoid fractures heal well, but the sequela phase may involve long-term monitoring. Follow-up care focuses on assessing functional recovery and addressing any chronic symptoms. Regular evaluations help prevent complications like arthritis or reduced mobility.

Complications

• Avascular necrosis of the scaphoid due to disrupted blood supply during the original injury.
• Chronic wrist pain or stiffness.
• Post-traumatic arthritis from altered joint mechanics.

Lifestyle & Prevention

• Avoid high-impact activities that stress the wrist.
• Use protective gear during sports or manual labor.
• Maintain bone health through proper nutrition and exercise to reduce fracture risk.

When to Seek Professional Help

Seek care if chronic pain worsens, swelling increases, or wrist function declines. Prompt evaluation is necessary if new numbness, tingling, or deformity occurs, as these may indicate complications.

Tips for Medical Coders

Document the sequela status clearly, noting the prior fracture and its timeline. Ensure the code S62.026S is used only when the condition is a late effect of the original injury, with no active acute fracture present. Include details on residual symptoms or functional limitations to support the sequela classification.
