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

Name of the Condition

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

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 a fracture that has failed to heal (nonunion), indicating the fracture site has not united after an expected period. The injury typically results from trauma or direct impact to the hand, leading to persistent pain, swelling, and 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.
• Poor blood supply to the fracture site.
• Inadequate initial treatment or immobilization.

Symptoms

• Persistent 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 in the hand or wrist.

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, deformity, or functional limitations. Imaging tests, such as X-rays or CT scans, to confirm the fracture and evaluate nonunion (lack of bone healing). Assessment of the fracture site for signs of delayed union or persistent gap.

Treatment Options

• Surgical intervention, such as bone grafting or internal fixation, to promote healing.
• 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 infection or further complications.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Follow-up care typically includes regular imaging to assess healing progress and functional evaluations. Long-term management may involve ongoing therapy or additional interventions if healing is delayed.

Complications

• Chronic pain or stiffness in the hand.
• Persistent nonunion requiring further surgery.
• Infection at the fracture site.
• Reduced grip strength or functional impairment.
• Arthritis or joint damage in the affected area.

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 guidelines to support healing.

When to Seek Professional Help

Seek immediate medical attention if pain worsens, swelling increases, or there are signs of infection (e.g., redness, fever). Consult a healthcare provider if functional limitations persist or if the fracture site shows no improvement over time.

Tips for Medical Coders

Document the encounter as a subsequent visit for a fracture with nonunion. Include details about the fracture’s location (base of the fourth metacarpal, right hand), displacement, and confirmation of nonunion. Ensure clinical documentation supports the nonunion diagnosis and subsequent encounter status.
