S62.323K Displaced fracture of shaft of third metacarpal bone, left hand, subsequent encounter for fracture with nonunion

Name of the Condition

• Displaced fracture of shaft of third metacarpal bone, left hand, subsequent encounter for fracture with nonunion

Summary

A displaced fracture of the shaft of the third metacarpal bone in the left hand, with nonunion, refers to a break in the middle portion of the bone where fragments remain misaligned and have failed to heal properly. This code is used for follow-up care when the fracture has not united after an expected healing period, indicating a complication in the recovery process.

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 treatment.

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.
• 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 bone healing and nonunion.

Treatment Options

• Surgical intervention to realign the bone and promote healing, such as bone grafting or internal fixation.
• Immobilization with a cast or splint to stabilize the fracture.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and strength.
• Monitoring for signs of healing or further complications.

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 as needed. Long-term outcomes may include persistent pain or reduced hand function if healing is not achieved.

Complications

• Chronic pain or discomfort.
• Reduced range of motion in the hand or fingers.
• Increased risk of future fractures.
• Infection, if surgery is required.
• Nerve or blood vessel damage.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or manual labor.
• Maintain bone health through proper nutrition and exercise.
• Follow post-treatment instructions carefully to support healing.

When to Seek Professional Help

Seek medical attention if symptoms worsen, new pain or swelling develops, or there is no improvement in healing over time. Prompt evaluation is important to address nonunion and prevent further complications.

Tips for Medical Coders

This code is specific to a subsequent encounter for a displaced fracture of the shaft of the third metacarpal bone in the left hand with nonunion. Documentation should clearly indicate the fracture's status (nonunion) and the encounter type (subsequent). Ensure the left-hand laterality and metacarpal bone involvement are accurately recorded.
