S62.350K Nondisplaced fracture of shaft of second metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

A nondisplaced fracture of the shaft of the second metacarpal bone in the right hand, with nonunion and subsequent encounter, refers to a break in the midsection of the bone connecting the index finger to the wrist where the bone fragments remain aligned but have failed to heal properly. This condition occurs during a follow-up visit after initial treatment, indicating the fracture has not united within the expected timeframe.

Causes

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

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Occupational hazards involving manual labor.
• Smoking or poor nutrition affecting bone healing.
• Certain medical conditions (e.g., diabetes) that impair healing.

Symptoms

• Persistent pain at the fracture site.
• Swelling or tenderness that does not resolve.
• Limited range of motion in the hand or fingers.
• Possible clicking or grinding sensation with movement.
• No visible deformity (due to nondisplacement).

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 nonunion and evaluate bone alignment. Review of prior treatment and healing progress.

Treatment Options

• Extended immobilization with a cast or splint to encourage healing.
• Bone stimulation therapies (e.g., electrical or ultrasound) to promote union.
• Surgical intervention, such as bone grafting or internal fixation, for persistent nonunion.
• Pain management using medications or physical therapy to restore function.

Prognosis and Follow-Up

Prognosis depends on the severity of nonunion and response to treatment. Most cases resolve with appropriate intervention, but healing may take longer than initial fractures. Regular follow-up imaging and clinical assessments are necessary to monitor progress.

Complications

• Chronic pain or discomfort.
• Reduced hand function or grip strength.
• Increased risk of future fractures.
• Potential need for additional surgery.

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-treatment instructions carefully to optimize healing.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility declines. Contact a healthcare provider if signs of infection (e.g., redness, fever) appear or if the fracture site does not improve with treatment.

Tips for Medical Coders

Document the subsequent encounter for fracture with nonunion, specifying the right-hand second metacarpal shaft and nondisplacement. Include details on prior treatment, imaging results, and clinical findings to support the nonunion diagnosis. Ensure documentation aligns with the ICD-10-CM code S62.350K.
