S62.322K Displaced fracture of shaft of third metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Name of the Condition

• Displaced fracture of shaft of third metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Summary

A displaced fracture of the shaft of the third metacarpal bone in the right hand involves a break in the middle portion of the bone with misaligned fragments. This code specifies a subsequent encounter for a fracture that has failed to heal (nonunion) after an initial injury. Nonunion occurs when the bone does not properly fuse during the expected healing period, requiring additional medical attention.

Causes

Direct trauma, such as a fall or blow to the hand. Sports-related injuries or accidents. Inadequate initial treatment or immobilization. Poor blood supply to the fracture site.

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Smoking or poor nutrition, which impairs healing.
• Displaced or severe initial fracture patterns.

Symptoms

• Persistent pain at the fracture site, often lasting beyond the typical healing time.
• Swelling or tenderness that does not improve with time.
• Limited mobility or stiffness in the hand or fingers.
• Possible deformity or instability in the affected area.

Diagnosis

Physical examination to assess pain, swelling, or deformity. Imaging tests, such as X-rays or CT scans, to evaluate bone healing and confirm nonunion. Assessment of prior treatment history and healing timeline.

Treatment Options

• Surgical intervention to realign the bone and promote healing, such as bone grafting or internal fixation.
• Extended immobilization with a cast or splint to support new bone growth.
• Pain management with medications.
• Physical therapy to restore function and strength once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. Follow-up imaging and clinical evaluations are necessary to monitor healing. Recovery may be prolonged, and some patients may experience residual stiffness or weakness.

Complications

• Chronic pain or discomfort.
• Persistent nonunion requiring additional surgery.
• Reduced hand function or mobility.
• Risk of arthritis in the affected joint over time.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow prescribed rehabilitation plans to support healing.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Use protective gear during sports or manual labor to prevent reinjury.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility declines after initial treatment. Prompt evaluation is important if signs of infection (e.g., redness, fever) or new deformity appear.

Tips for Medical Coders

Document the fracture site (third metacarpal, right hand), displacement, and the presence of nonunion. Specify "subsequent encounter" to indicate follow-up care for a fracture that has not healed. Include details on prior treatments and imaging results to support the nonunion diagnosis.
