S62.126S Nondisplaced fracture of lunate [semilunar], unspecified wrist, sequela

Name of the Condition

• Nondisplaced fracture of lunate [semilunar], unspecified wrist, sequela

Summary

A nondisplaced fracture of the lunate (semilunar) bone in the unspecified wrist, sequela, refers to a residual condition following a previous fracture where the bone fragments remain in their normal anatomical position. The lunate is a small, crescent-shaped carpal bone essential for wrist stability and movement. This sequela indicates the fracture has healed, but residual effects may persist, requiring ongoing evaluation to manage symptoms or functional limitations.

Causes

This condition results from a prior traumatic event, such as a fall onto an outstretched hand, a direct blow to the wrist, or a twisting injury, that caused the initial nondisplaced fracture. The sequela phase occurs after the acute injury has resolved, with the fracture site having healed but potentially leaving lasting effects on wrist function or structure.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, especially in older adults.
• Previous wrist injuries or fractures.
• High-impact occupational activities or accidents.

Symptoms

• Persistent pain or tenderness in the wrist.
• Swelling or bruising around the wrist area.
• Limited range of motion in the wrist.
• Difficulty gripping objects.
• Stiffness or reduced wrist mobility.

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRI, to evaluate the healed fracture site and identify any residual structural changes or functional limitations.

Treatment Options

• Rehabilitation: Physical therapy to improve wrist strength, flexibility, and range of motion.
• Pain management: Medications or modalities to alleviate persistent discomfort.
• Supportive devices: Braces or splints to stabilize the wrist during activity.
• Surgical evaluation: Considered if residual symptoms or functional impairment persist.

Prognosis and Follow-Up

Most patients experience gradual improvement in symptoms and function with appropriate rehabilitation. Follow-up care focuses on monitoring for persistent pain, stiffness, or functional limitations. Long-term outcomes depend on the severity of the initial injury and adherence to rehabilitation protocols.

Complications

• Chronic wrist pain or stiffness.
• Reduced wrist mobility or grip strength.
• Increased risk of future wrist injuries.
• Potential for post-traumatic arthritis in the affected joint.

Lifestyle & Prevention

• Engage in regular wrist-strengthening exercises to maintain flexibility and strength.
• Use protective gear during high-risk activities to minimize trauma.
• Avoid repetitive wrist motions that may exacerbate symptoms.
• Maintain bone health through adequate nutrition and exercise.

When to Seek Professional Help

Seek medical attention if persistent pain, swelling, or limited wrist mobility interferes with daily activities. Prompt evaluation is recommended if symptoms worsen or new complications arise.

Tips for Medical Coders

This code is used for a sequela (late effect) of a nondisplaced lunate fracture in the unspecified wrist. Documentation should specify the residual effects of the healed fracture, such as persistent pain, stiffness, or functional limitations, to support the sequela diagnosis. Ensure the code aligns with the patient's current clinical status and prior fracture history.
