S62.354K Nondisplaced fracture of shaft of fourth metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of shaft of fourth metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Summary

A nondisplaced fracture of the shaft of the fourth metacarpal bone in the right hand, with a subsequent encounter for fracture with nonunion, refers to a break in the midsection of the bone connecting the ring finger to the wrist where the bone fragments remain aligned but have failed to heal properly. This condition occurs after an initial fracture and indicates the bone has not united during the expected healing period.

Causes

Direct trauma, such as a fall or blow to the hand. Sports-related injuries or accidents. Repetitive stress or overuse. Inadequate immobilization or premature weight-bearing after the initial fracture.

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Smoking or poor nutrition, which can impair healing.
• Certain medical conditions, such as diabetes or vascular disease.

Symptoms

• Persistent pain and swelling in the hand.
• Tenderness or bruising around the affected area.
• Difficulty moving the fingers or hand.
• Possible clicking or grinding sensation with movement.
• No visible deformity, as the fracture remains nondisplaced.

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, or functional limitations. Imaging tests, such as X-rays or CT scans, to confirm the fracture and evaluate for nonunion. Assessment of healing progress compared to expected timelines.

Treatment Options

• Prolonged immobilization with a cast or splint to encourage healing.
• Bone stimulation therapies, such as ultrasound or electrical stimulation.
• Surgical intervention, including bone grafting or internal fixation, if nonunion persists.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and strength once healing is achieved.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Most cases resolve with appropriate intervention, but healing may take longer than a typical fracture. Regular follow-up appointments and imaging are necessary to monitor progress. Full recovery of function is often possible with proper care.

Complications

• Chronic pain or discomfort.
• Persistent limited mobility or stiffness.
• Increased risk of future fractures in the affected bone.
• Infection, particularly if surgical intervention is required.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Use protective gear during sports or manual labor.
• Follow post-fracture care instructions carefully to promote healing.

When to Seek Professional Help

Seek immediate medical attention if pain worsens, swelling increases, or new symptoms develop, such as fever or signs of infection. Consult a healthcare provider if the fracture does not improve with conservative treatment or if mobility does not return as expected.

Tips for Medical Coders

Document the encounter as a subsequent visit for a fracture with nonunion, specifying the right fourth metacarpal bone. Include details on prior treatment, imaging results, and clinical findings supporting the nonunion diagnosis. Ensure documentation aligns with the ICD-10-CM code S62.354K and reflects the ongoing nature of the condition.
