S62.325P Displaced fracture of shaft of fourth metacarpal bone, left hand, subsequent encounter for fracture with malunion

Name of the Condition

• Displaced fracture of shaft of fourth metacarpal bone, left hand, subsequent encounter for fracture with malunion

Summary

A displaced fracture of the shaft of the fourth metacarpal bone in the left hand involves a break in the middle portion of the bone, with the fragments misaligned. This injury is classified as a subsequent encounter for fracture with malunion, indicating the patient is receiving follow-up care after the initial fracture, and the bone has healed in a non-anatomical position. The fracture disrupts the normal alignment of the bone and may require ongoing management to address functional or cosmetic concerns.

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.
• Limited range of motion or functional impairment.

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 malunion to determine the degree of misalignment and impact on function.

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.
• Surgery may be required for severe malunion to realign the bone and improve function.

Prognosis and Follow-Up

Most fractures with malunion heal without major complications, but functional limitations or cosmetic concerns may persist. Follow-up care focuses on monitoring healing progress, assessing functional outcomes, and determining if additional interventions are needed. Long-term management may involve ongoing therapy or adaptive strategies to optimize hand use.

Complications

• Chronic pain or discomfort.
• Reduced grip strength or dexterity.
• Joint stiffness or arthritis.
• Nerve or tendon damage from malalignment.
• Need for surgical correction if malunion significantly impacts function.

Lifestyle & Prevention

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

When to Seek Professional Help

• Persistent pain or swelling that does not improve.
• Difficulty moving the hand or fingers.
• Visible deformity or worsening misalignment.
• Signs of infection, such as redness, warmth, or drainage.

Tips for Medical Coders

Document the presence of malunion and the subsequent encounter status clearly in the medical record. Ensure the fracture is described as displaced and specify the left hand and fourth metacarpal bone. Include details about the healing status and any functional limitations to support accurate coding.
