S62.125K Nondisplaced fracture of lunate [semilunar], left wrist, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of lunate [semilunar], left wrist, subsequent encounter for fracture with nonunion

Summary

A nondisplaced fracture of the lunate in the left wrist is a break where the bone remains in its normal anatomical position but has failed to heal properly, resulting in nonunion. This condition is assessed during subsequent encounters when healing has not progressed as expected, requiring ongoing evaluation and management.

Causes

A nondisplaced lunate fracture with nonunion typically results from trauma to the wrist, such as falls onto an outstretched hand or direct impact. Factors contributing to nonunion may include inadequate immobilization, poor blood supply to the bone, or underlying health conditions that impair healing.

Risk Factors

• Participating in high-impact sports or activities with wrist trauma risk
• Osteoporosis or weakened bone structure
• Previous wrist injuries or fractures
• Smoking or other habits that impair bone healing
• Certain medical conditions affecting bone metabolism

Symptoms

• Persistent pain or tenderness in the left wrist
• Swelling or bruising around the wrist area
• Limited range of motion in the wrist
• Difficulty gripping objects
• Possible clicking or grinding sensation during wrist movement

Diagnosis

Physical examination by a healthcare provider to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays or CT scans, to confirm the fracture and evaluate healing progress. Additional assessments may include MRI to assess bone viability or bone scans to detect nonunion.

Treatment Options

• Surgical intervention, such as bone grafting or internal fixation, to promote healing
• Prolonged immobilization with a splint or cast to stabilize the fracture
• Pain management with medications like NSAIDs or analgesics
• Physical therapy to restore strength and mobility after healing
• Monitoring for signs of improved bone union or complications

Prognosis and Follow-Up

Prognosis depends on the success of treatment and underlying factors affecting healing. Follow-up appointments are essential to monitor progress, with imaging to assess bone union. Full recovery may take longer than typical fractures, and some patients may experience residual stiffness or pain.

Complications

• Chronic pain or discomfort in the wrist
• Persistent limited range of motion
• Risk of arthritis in the wrist joint
• Need for additional surgical procedures
• Potential for long-term functional impairment

Lifestyle & Prevention

• Avoid high-impact activities that risk wrist injury until fully healed
• Use protective gear during sports or work involving wrist stress
• Maintain bone health through proper nutrition and exercise
• Follow post-treatment guidelines for immobilization and activity restrictions
• Quit smoking or reduce alcohol intake to support bone healing

When to Seek Professional Help

Seek medical attention if you experience worsening pain, increased swelling, new numbness or tingling, or difficulty moving the wrist. Prompt evaluation is important if nonunion is suspected or if symptoms do not improve with treatment.

Tips for Medical Coders

This code (S62.125K) is used for a nondisplaced lunate fracture in the left wrist during a subsequent encounter when nonunion is present. Documentation should specify the fracture type, location, and the presence of nonunion. Ensure the encounter is classified as subsequent and that the nonunion is clearly noted to support accurate coding.
