S62.314P Displaced fracture of base of fourth metacarpal bone, right hand, subsequent encounter for fracture with malunion

Name of the Condition

• Displaced fracture of base of fourth metacarpal bone, right hand, subsequent encounter for fracture with malunion

Summary

A displaced fracture of the base of the fourth metacarpal bone in the right hand is a break in the proximal (base) portion of the fourth metacarpal, where the bone fragments are misaligned. This condition is documented as a subsequent encounter for fracture with malunion, indicating the fracture has healed in an abnormal position. The injury typically results from trauma or direct impact to the hand, leading to pain, swelling, and potential functional impairment.

Causes

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

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Occupational hazards involving manual labor or repetitive hand movements.

Symptoms

• Pain and swelling in the right hand.
• Tenderness or bruising around the affected area.
• Difficulty moving the fingers or gripping objects.
• Possible visible deformity or misalignment.
• Limited range of motion due to malunion.

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, deformity, or malunion. Imaging tests, such as X-rays, to confirm the fracture and evaluate its extent, displacement, and healing status.

Treatment Options

• Immobilization with a cast or splint to support healing.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and strength.
• Surgical intervention may be considered for severe malunion or functional impairment.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and functional impact. Follow-up care may include regular monitoring, imaging, and rehabilitation to optimize recovery. Long-term outcomes vary based on treatment and individual factors.

Complications

• Chronic pain or discomfort.
• Reduced hand function or grip strength.
• Arthritis or joint stiffness.
• Nerve or tendon damage.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through proper nutrition and exercise.
• Avoid repetitive stress on the hand when possible.
• Seek prompt treatment for hand injuries to reduce malunion risk.

When to Seek Professional Help

• Persistent pain, swelling, or deformity.
• Difficulty moving fingers or gripping objects.
• Signs of infection, such as redness, warmth, or drainage.
• Sudden worsening of symptoms.

Tips for Medical Coders

Document the presence of malunion and specify the encounter as subsequent. Include details on fracture alignment, functional impact, and any treatment provided. Ensure documentation supports the diagnosis and aligns with clinical findings.
