S62.357K Nondisplaced fracture of shaft of fifth metacarpal bone, left hand, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of shaft of fifth metacarpal bone, left hand, subsequent encounter for fracture with nonunion

Summary

A nondisplaced fracture of the shaft of the fifth metacarpal bone in the left hand, with a subsequent encounter for fracture with nonunion, refers to a break in the midsection of the bone connecting the little finger to the wrist where the bone fragments remain aligned, but healing has not occurred as expected. This condition indicates the fracture has failed to unite after an initial injury, requiring ongoing medical attention.

Causes

Direct trauma, such as a fall or blow to the hand. Sports-related injuries or accidents. Repetitive stress or overuse.

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Occupational hazards involving manual labor.
• Poor blood supply to the fracture site.
• Inadequate immobilization during initial healing.

Symptoms

• Persistent pain and swelling in the hand.
• Tenderness or bruising around the affected area.
• Difficulty moving the fingers or hand.
• Possible deformity or misalignment (less common with nondisplaced fractures).
• Delayed or absent healing signs, such as reduced pain or improved mobility.

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, or deformity. Imaging tests, such as X-rays, to confirm the fracture and evaluate its extent. Assessment of healing progress over time to determine nonunion.

Treatment Options

• Immobilization with a cast or splint to promote healing.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and strength.
• Surgery may be required to stabilize the fracture or promote union.
• Bone grafting or other interventions to encourage healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and treatment effectiveness. Regular follow-up appointments are necessary to monitor healing progress. Long-term outcomes may include persistent pain or reduced hand function if union is not achieved.

Complications

• Chronic pain or discomfort.
• Reduced hand mobility or strength.
• Increased risk of further injury.
• Potential need for additional surgical interventions.

Lifestyle & Prevention

• Avoid high-impact activities until fully healed.
• Use protective gear during sports or manual labor.
• Maintain bone health through proper nutrition and exercise.
• Follow medical advice for immobilization and rehabilitation.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility declines. Contact a healthcare provider if signs of infection, such as redness or fever, develop.

Tips for Medical Coders

Document the fracture's status (nondisplaced), location (shaft of fifth metacarpal, left hand), and the presence of nonunion. Include details of subsequent encounters, such as follow-up visits or treatment adjustments, to support accurate coding. Ensure documentation reflects the fracture's failure to unite and any interventions performed.
