S62.324A Displaced fracture of shaft of fourth metacarpal bone, right hand, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of shaft of fourth metacarpal bone, right hand, initial encounter for closed fracture

Summary

A displaced fracture of the shaft of the fourth metacarpal bone in the right hand involves a break in the middle portion of the bone, with the fragments misaligned. This injury typically results from trauma or impact to the hand, leading to a fracture that disrupts the normal alignment of the bone. The term "initial encounter for closed fracture" indicates this is the first episode of care for a fracture where the skin remains intact.

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.

Symptoms

• Pain and swelling in the hand.
• Tenderness or bruising around the affected area.
• Difficulty moving the fingers or hand.
• Possible deformity or misalignment.

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.

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 for severe or displaced fractures to realign the bone.

Prognosis and Follow-Up

Most fractures of the metacarpal shaft heal well with appropriate treatment. Follow-up care typically involves monitoring for proper healing and assessing functional recovery. Physical therapy may be recommended to restore full range of motion and strength.

Complications

• Nonunion or delayed healing of the fracture.
• Malunion, where the bone heals in a misaligned position.
• Stiffness or reduced mobility in the hand or fingers.
• Nerve or tendon damage in severe cases.

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive hand stress or overuse.
• Practice safe techniques in manual labor to reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, deformity, or inability to move the hand after an injury. Persistent pain, numbness, or signs of infection (e.g., redness, fever) also warrant prompt evaluation.

Tips for Medical Coders

Document the specific metacarpal bone involved (fourth), the hand (right), and the fracture type (displaced, closed) to ensure accurate coding. Note the "initial encounter" status to reflect the first episode of care for this closed fracture. Include details of the injury mechanism and clinical findings to support code assignment.
