S62.356K Nondisplaced fracture of shaft of fifth metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

A nondisplaced fracture of the shaft of the fifth metacarpal bone in the right hand, with 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 have failed to heal properly. This code is used for follow-up care when the fracture site shows delayed or incomplete healing, indicating a nonunion status.

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).
• Lack of improvement in symptoms over time.

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. Additional imaging, like CT scans, may be used to assess healing status and detect 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.
• Surgical intervention, such as bone grafting or internal fixation, to address nonunion.
• Use of bone-stimulating devices to encourage healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. Follow-up care is essential to monitor healing progress and adjust treatment plans as needed. Regular imaging may be required to assess bone union.

Complications

• Chronic pain or discomfort.
• Reduced hand function or mobility.
• Increased risk of further injury.
• Potential need for additional surgeries.
• Long-term disability in severe cases.

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 post-injury care instructions carefully to support healing.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility does not improve. Consult a healthcare provider if symptoms persist beyond expected healing time or if new deformities develop.

Tips for Medical Coders

Document the fracture site, laterality (right hand), and the presence of nonunion. Include details of follow-up encounters, imaging results, and treatment plans to support the use of this code. Ensure documentation reflects the ongoing nature of the fracture and the nonunion status.
